Far beyond the eight familiar planets in oursolar system , countless bizarre and uttermost worlds await find — and some have already been found .
Thanks to quickly come on telescope engineering , astronomers have notice more than 5,600 planets outside our solar organization . Theseexoplanets , as scientists call them , are worlds of lava , and earth of water . They ’re creation being ravaged by the estrus of their stars , and earth locked in unceasing night . There are worlds that depend like they were steal straight from " Star Wars , " and humans that may hold exotic forms of life never dreamed up in science fiction .
Join us as we tour some of the strangest and most fascinating exoplanets in our ever - surprising universe .
The “hell planet” where it rains lava
55 Cancri eis a jolty world about eight prison term the size of Earth , making it a type of exoplanet known as a " super Earth . " Despite its rich size , nothing is " super " about the living conditions here . Often nicknamed the " pit major planet , " 55 Cancri e is completely covered in flow seas of lava , and it may evenrain lavathere as well . The exoplanet is located 41 light - years from Earth , making it a democratic target for studies ( but not for summer getaways ) .

The water world with (potentially) living oceans
K2 - 18 b is a magnanimous world located about 120 light - years from the sunlight . It live the " Linosyris vulgaris zona " around its star , think of that liquid weewee ( and potentially life ) could exist there . A late analysis with theJames Webb Space Telescope(JWST ) supports the idea that the exoplanet may have its own liquid water ocean — and that the oceanmay be home to living creature . In the bailiwick , JWST detected possible trace of dimethyl sulfide , a chemical known to be let out only by phytoplankton on Earth , in the exoplanet ’s atmosphere .
The real-world “Tatooine”
Luke Skywalker would feel right at home onKepler-16b . This exoplanet is the first fuck circumbinary planet — a satellite that orbit two stars at the same time , just like Tatooine from the Star Wars enfranchisement . However , because this vast planet has a gassy aerofoil interchangeable to Saturn ’s , even a Jedi would have a hard meter finding their footing on this exoplanet , which is located about 200 light - years from the sun .
The rule-breaking behemoth
Thegiant exoplanet LHS 3154bhas scientists inscribe their heads , because it seems far too heavy for its midget star . This satellite , which is about 13 time more massive than Earth but orbits a hotshot nine timesless massivethan the Sunday , does n’t seem like it could survive , researchers said upon its breakthrough in 2023 . Future studies of this " insufferable " world could upend the known rules of satellite formation .
The largest exoplanet in the known universe?
With twice the r of Jupiter , the exoplanet HAT - P-67 boron may be thelargest bang major planet in the existence , in terms of width . But despite its monumental cinch , there are moremassiveworlds out there . This honkin ' world , settle about 1,200 light - age from Earth , has a very abject denseness , giving it only about one - third the mass of Jupiter .
The “fluffy” planet where it rains sand
Located 200 light - years from Earth , the exoplanet WASP-107b also has a very low-down density , get it come along " fluffy " in telescope observations . A recentJWST subject area of the planetrevealed cloud potentially made of delicately - granulate silicate particles , imply it may literally rain down sand on this puffed - up world .
The “eyeball planet” with potentially living seas
Sitting just 50 clear - years from Earth , thebeady - eyed exoplanet LHS 1140 bmay be a prospect for alien life thanks to its one - of - a - variety surface . Scientists study the world with JWST found that the planet may be comprehend in ice — except for the one part of its surface that permanently points toward its server principal . Here , the star ’s rut may melt just enough ice for a round , limpid water ocean to spring , according to the researchers . Besides giving the satellite a distinguishable bull’s - eye appearance , this rarefied ocean may be a quality place for extraterrestrial life story to flourish , the team write .
The rotten-egg world
Theexoplanet HD 189733 B vitamin , located about 64 light - twelvemonth from Earth , has a chemic piece of music so distinct that astronomers can practically smack it from across the galaxy . A recent JWST sketch of the planet feel that its atmosphere contains significant quantity of hydrogen sulfide — a toxic and flammable gas given off by decaying organic subject and volcanoes on Earth — which smell like rotten eggs . The smelly egg satellite is far too red-hot for life to exist ( thank goodness ) , but the mere fact that scientists can discover such distinct molecules in its atmosphere is a skillful sign that JWST may soon be able to find signature of sprightliness elsewhere in the universe .
The “Vulcan planet” that may not exist
In a remarkable case of science fiction reflected in realness , scientists have reported the find of a major planet similar to Vulcan , the home existence of Dr. Spock in the Star Trek enfranchisement . The satellite was attain in 2018 around the real star 40 Eridani A — the very same lead that host Spock ’s home planet in the celebrated sci - fi serial . However , recent follow - up observationsof the star have call in the planet ’s existence into head ; subtle wobbles in the champion ’s faint signature may ensue not from a nearby planet ’s tugging on it but rather from regular eruptions on the star topology ’s surface . The existence of the Vulcan planet , name HD 26965 boron , now seems in doubt .
The Earth-like planet around a small, red star
Earth may have a long - lost twin in a nearby star system . NamedGliese 12 b , the planet orbits a hot , red genius in a system close to 40 light - years from Earth . Remarkably , the exoplanet appears to have a breadth 1.1 times that of Earth , consecrate it similar properties to our own planet . And while Gliese 12 b orbits its habitation star much more close than our planet does the sun ( one year there endure about 13 Earth days ) , that star is also much small , keeping the satellite in the habitable zone where liquid water can form on the planet ’s surface . That mean our distant twin may even have its own variant of lifetime .
The Earth-size planet with eternal night
Not all Earth - size planets are lucky enough to be habitable . TakeSPECULOOS-3 b , a stony , Earth - like worldwhose orbit around its ruby dwarf star is a petty too close for solace . Completing an orbit every 17 hours , the rocky earth is exposed to so much actinotherapy that its air was likely blasted away long ago , result the luckless planet totally barren . The blackguard temperature are n’t a world phenomenon , however ; this planet is tidally interlock , think of one side always look its star in perpetual day , while the other side model in perpetual night .
The red volcano world that’s “melting from within”
Astronomers have discovered a planet in a remote star system that looks like push through with so many vent , the earth literally glow red when encounter through telescopes . Thesmoldering exoplanet , named TOI-6713.01 , is place roughly 66 light - years from Earth and orbit its star closely , complete a eyelet every 2.2 Earth days . Observations evoke the major planet is covered in liquefied lava , released by century of dynamic volcano . The planet is also open to incredible internal friction from the sombreness of its star and its neighboring planet , which may be causing the world to literally melt down from within .
The gas giant with bullet-like wind
Scientists have represent the weather on an tremendous exoplanet 280 short - eld from Earth , and the prognosis looks down . The planet , named WASP-43b , is tidally locked , with one monumental face always pointing toward its lead and the other dissemble in ageless dark . substantial temperature differences between the two sides drive fierce winds , which scientist estimated to boast at up to 5,600 miles per hour ( 9,000 km / h ) — several multiplication degraded than a speeding bullet .
The hellish world with glorious rainbows
Theexoplanet WASP-76 b — turn up about 637 easy - year from Earth — is not the eccentric of position you ’d want to vacation . orb 20 time closer to its home genius than Mercury orbit the sun , the planet ’s dayside is count on to hit 4,350 degrees Fahrenheit ( 2,400 degrees Celsius ) , give it a true Scheol world . There is one attractor , however : A strange bright spotlight observed on the planet ’s surface , mightily where the daytime and night side receive , could be a " glory " — a rarefied visual phenomenon , sometimes seen on Earth , made up of concentric rainbow gang forming a giant dress circle .
The giant planets orbiting dead stars
One twenty-four hours , the sun will die — but some planets in our solar scheme may last on . Scientists made this inference after hear two tremendous planets orbiting " dead " white midget champion in distant star systems . NamedWD 1202 - 232 and WD 2105 - 82 , the planets are estimated to be between one and seven clip as massive as Jupiter , and both orbit minuscule , beat mavin at length of at least 11.5 times that between Earth and the sunlight . Their find , if confirmed , hints that our solar system ’s comparable planets , Jupiter and Saturn , may be able-bodied to survive the inevitable death of the sun one day . ( Earth , sadly , islikely to be swallowed upduring our asterisk ’s final expanding upon . )
The “rogue” planets of Orion
Most known planets domain stars , but there may be unnumbered others that do n’t . Scientists using the JWST have discoveredhundreds of loose - floating " rogue planets"zooming through the Orion Nebula , untethered to any star . queerly , about 80 of these rogue universe are trapped in binary orbits with each other , whirl around through place in duet . Scientists are not certain how these worlds got ejected from their home asterisk systems or why they are trapped in binary orbits . Given that these planets are just about as monolithic as Jupiter , scientists have knight them Jupiter - mint binary objects — or JuMBOs , for inadequate .
The distant planet we can actually see
scientist detect most exoplanets indirectly , by watching changes in the light emitted by distant stars . But in 2004 , researchers gotdirect visual verification of an alien worldfor the first metre ever . Called 2M1207b , the exoplanet is situate about 170 abstemious - long time away , in the configuration Centaurus , and is a gas behemoth about five times more monumental than Jupiter . The squad spot the removed globe by look at it in three different infrared wave band , which helped reveal the planet ’s heat while blocking the lightness of its home star . Since this groundbreaking find , roughly 200 exoplanets have been get a line through direct imaging , while more than 5,000 others have been disclose through other mean value .
The planet with clouds of quartz
Can you opine a sundown filtered through a crystal sky ? That may be a reality on theexoplanet WASP-17b , a Jupiter - same gas giant that ’s so hot that its cloud are made of quartz crystals , observations with JWST suggest . The major planet orbits extremely close to its nursing home champion , giving it an atmosphere with temperatures reach a blistering 2,700 F ( 1,500 C ) . This heat forms tiny , gumption - size silica particles in the satellite ’s atmosphere , which may coalesce into cloud of staring quartz , researchers intimate .
The baby Jupiter about to be born
Exoplanet - track down scientist zoom in on not just be worlds but alsoworlds that are about to be born . While studying the realm around the star V960 Mon , located about 5,000 light - year from Earth , scientists spot a clumpy field of flatulency where two tendril of textile are apparently being funnel into distinct , satellite - alike puffiness . concord to the researcher , who made the discovery using the European Southern Observatory ’s Very enceinte Telescope and the Atacama Large Millimeter / submillimeter Array , this is the first sentence scientist have imaged a young star system on the brink of birthing its first giant planets .
The sibling planets dancing in lockstep
Around the distant sensation PDS 70 , locate 370 light - years from Earth , residesan fantastically rarefied pair of sibling planet . One fully formed Earth roughly the size of Jupiter seem to eddy around its horde star ; behind it , in the same eye socket , is an enormous cloud of accelerator pedal and dust that researchers distrust may be the planet ’s partially formed sib . Although only one of the object seems to be a full - mature major planet , the pair is the first evidence of rare " Trojan planets " — two worlds that constitute at nearly the same time , in roughly the same post around their home wiz , moving in the precise same orbit .
The planet turning its star into a “spiral galaxy”
About 500 million light - class from Earth is a star system that await suspiciously familiar . Wrapped in two dusty spiral arms , it resemble our ownMilky Waygalaxy — although on a much , much smaller scale . The reason for this star ’s galactic appearance ? Astronomers suspect it ’s because of a hide out , Jupiter - size planet knight MWC 758 c , which used its massive gravitative drag to sculpt the star ’s cocktail dress of junk into spectacular spiral weaponry . The planet has yet to be fully confirmed , but simulations show it ’s a likely reason of its home star ’s unexpended facial expression .
The mirror world that shouldn’t exist
Most planets reflect at least a bite of their home base star ’s light . Butthe exoplanet LTT9779 breflects a banging 80 % of its star ’s incoming beam — the eminent reflectiveness of any planet ever discovered . The paint to the satellite ’s impressive albedo is a layer of metal clouds that surrounds it . scientist mistrust the Neptune - size earth ’s sky is mostly full of silicate , or glass , and titanate , a Strategic Arms Limitation Talks containing titanium — turning the planet ’s ambiance into a regular mirror . The planet ’s existence flummox a puzzler for scientist : The world orbit so close to its star that its atmosphere should have been blown by by now . The key to its endurance may be the metal in the major planet ’s sky , which may be too great for solar wind to savage it aside .
The “zombie” planet that survived its star’s death
The exoplanet8 Ursae Minoris b , also know as Halla , is a hot , Jupiter - corresponding universe located 520 light - years from Earth . Observations suggest the massive earthly concern should have been totally incinerated by its habitation star , which has already entered its reddish giant form and appears to have long since ballooned outwards into its system , scorching everything in its itinerary , before shrinking back to its current size . The fact that Halla orb comparatively close to the star suggest it was either born after the whizz shrink again or the star that ’s seeable today is one of two binary lead that merge , preventing either one from expanding on its track of destruction .
The water world with a steam atmosphere
Theexoplanet GJ 1214bis located just 40 light - year from Earth , but it ’s coated in so many thick clouds that scientist had a hard clip studying it until lately . Using JWST ’s infrared vision to peer through the cloud , scientists take apart the planet and see what appeared to be an aura made of steam , suggesting the world below may hold in significant amount of weewee .
The Earth-like planet with no atmosphere
Around the distant sensation TRAPPIST-1 , seven rocky , ground - sizing planets swirl through the star ’s habitable geographical zone . Whether any of these planet contain the right conditions for life is a question astronomer are eagerly look into . But one of them , TRAPPIST-1b , may be officially out of the running . JWST ’s observations of the rocky , Earth - like domain uncover that the major planet is about as hot as an oven — a whopping 450 F ( 232 C ) — and almost certainly does n’t have an atmosphere . Some of the scorching world ’s neighbors may be better place for living to come out , but more research is involve to fuck for certain .
The extraterrestrial sandstorm planet
scientist using JWST have spotted a giant sandstorm remonstrate on the exoplanetVHS 1256 b , locate roughly 40 light - years from Earth . An enormous world that ’s far from its whiz , the " super - Jupiter " postulate about 10,000 years to complete a single orbit . That large distance intend scientist can see the planet ’s atmosphere comparatively intelligibly , without too much starlight getting in the way . Recent observance record incredibly red-hot clouds made of silicate particles swirling through the satellite ’s ambience . According to the researchers , this may be evidence of a gargantuan junk violent storm .
The planet hotter than a star
KELT-9bis an extremely hot , Jupiter - like major planet locate 670 sluttish - years from Earth . With an estimated surface temperature of 7,800 F ( 4,300 C ) , it was deemed the hottest exoplanet ever discovered upon its detection and is even hotter than some asterisk . This vivid heat has a nasty wallop on the major planet ’s air : On KELT-9b ’s dayside , the heat of the nearby star beats down so intensely that atomic number 1 corpuscle in KELT-9b ’s ambiance are literally ripped to shreds and blown across the planet . With one - one-half of the planet ’s aura constantly fade , this world is one extraterrestrial destination you ’d definitely want to ward off .
The toxic football planet
locate about 900 sluttish - years from Earth , theexoplanet WASP-121bis so red-hot that profound metallic element are always boil through its atmosphere and discharge into space . Scientists spotted branding iron and atomic number 12 molecules so high above the planet ’s surface that they could break away the pull of sobriety and drift away . The extreme heat comes from the planet ’s ultraclose proximity to its host star . The planet is so close , in fact , that tidal forces return by the star ’s gravity have stretch the planet into a football shape that distinguishes it from the spherical humanity most often discover .
The ultrasmall world moving at breakneck speed
locate 35 light - years from Earth , L 98 - 59bis one of the minor exoplanets ever discovered , with a mickle just 0.4 time that of Earth . The diminutive creation also skyrocket around its home plate star at breakneck speed , complete an orbital cavity in just two Day , six hr . Because of this , the planet receives roughly 22 times as much zip from its domicile star as Earth does from the Sunday , almost sure rendering the tiny , fast - moving planet uninhabitable .
Earth’s “older cousin”
The exoplanetKepler-452 bappears so similar to our house major planet thatNASAhas dubbed the world " Earth ’s old cousin . " The rocky exoplanet orbits a sunlike star at virtually the same distance that our planet orbits the Sunday , with a year there live on about 384 days . That puts the major planet firmly in the inhabitable geographical zone , where liquid water could form on its surface . unhappily , our cousin-german will persist estranged for a good while longer : At nearly 1,800 light - years from Earth , the planet would take at least 30 million years to pass on by spacecraft .
The bizarrely close sibling planets
Theexoplanet Kepler-36bis a rocky reality that ’s about 1.5 times the size of it of Earth and orbits bizarrely close to its neighboring earth , the Neptune - like exoplanet Kepler-36c . The two alien mankind make super unaired approach to each other every 97 days , on average ; during those cosmic family reunions , the two planets are separated by less than five Earth - moonlight distances . These ultraclose encounters wield tremendous tidal forces on the sibling major planet , maybe promoting active volcanism on the rocky Kepler-36b .
The unlucky planet around a toddler star
The exoplanetAU Microscopii b , located about 32 light - year from Earth , is unlucky enough to have form a scant 6 million mile ( 9.6 million km ) from its host maven — an passing immature , hot , temperamental red gnome . Estimated to be just 23 million age old , the star is a bare yearling in cosmic terminus . ( The sun , by compare , is 4.6 billion years old . ) The young wizard routinely erupts with blasts of radiation therapy thousands of times stronger than the worst solar flares the sun can spue out — and pitiable AU Microscopii b is often in the firing line . stargazer have discover huge globs of planetary material orbiting near the distant world , suggesting that the temperamental star is blasting away pieces of the planet ’s aura chip by bit .
