  • Space is a weird place- how weird? Well, how's  planets made out of solid diamond and burning  

  • ice strike you as weird? Here's 10  of the weirdest planets out there.

  • 10. Every Day A Birthday

  • Here on earth you have to wait  until you're 21 to drink legally,  

  • if you lived on Wasp-18b though that wouldn't  be much of a problem, as you'd only be waiting  

  • 21 days until you were legally able to  drink. Located 410 light years from Earth,  

  • Wasp-18b is only about 1.9 million miles  (3.1 million km) from its parent star,  

  • and its orbital velocity is so great that it  zips around its star in less than 24 hours.

  • Wasp-18b moves so fast because of  its incredible proximity to its sun.  

  • The closer you are to a source of gravitythe stronger the pull of that gravity on you.  

  • Therefore for a planet to remain in orbit  and not get swallowed up by its sun,  

  • it has to generate sufficient speed to overcome  the gravitational force of the sun. So basically,  

  • the closer you get to a star, the faster you have  to move or you'll end up falling into that star.  

  • Likewise, the further away you are the slower  you need to go to maintain a stable orbit.

  • Of course living on Wasp-18b would be  a bit of a problem unless you were in  

  • a space habitat above the planet, because  Wasp-18b is 10 times Jupiter's size, and just  

  • barely falls under the category of a brown dwarfcommonly thought of as 'failed stars' because they  

  • didn't get big enough to start fusion at their  cores or get their own reality tv shows. Also,  

  • due to tidal forces acting on the planetit'll eventually fall into its own sun,  

  • giving anyone living in its orbit  the worst sunburn in the universe

  • Speaking of speed and sunburnthis next planet has both to spare.

  • 9. Whiplash And Sunburn All At Once

  • Weather can be unpredictable here on earthwith the best weatherman barely able to tell  

  • you what the next week is going to be  like. However, weather on HD 80606 b  

  • is pretty predictable- if not the most extreme  in the galaxy. While at one point in its orbit  

  • you'll be enjoying balmy, Earthlike summer  weather, just a few weeks later you'll be  

  • cranking up the AC to hypermaximum as the  temperatures soar to thousands of degrees.

  • That's because HD 80606 b has a very  eccentric orbit, resulting in an elliptical  

  • orbital path that dips it to just undermillion miles at its closest to its sun,  

  • to 82 million miles at its furthest. This  eccentric orbit lead to scientists measuring  

  • a temperature change of 1,000 degrees fahrenheit  (500 C) to 2200 degrees (1200 C) in just  

  • six hours. Such severe temperature swings lead  toshock wave stormsthat propel superheated  

  • winds at 15 times the speed of sound, absolutely  shredding anything that might get in their way.

  • Scientists believe that the influence of  another star 1,000 astronomical units away-  

  • or 1,000 times the distance from the sun to  the Earth- is to blame for the extreme orbit,  

  • which is also inclined 90 degrees in a similar  fashion to Halley's Comet in our own solar system

  • This next planet would make you and every  descendant you have until the end of time  

  • rich beyond your wildest dreamsif it doesn't kill you instantly

  • 8.Galactic El Dorado

  • The legend of El Dorado tells of a secret  city made of pure gold, worth trillions to  

  • whoever could find it and plunder its richesTurns out, our galaxy has something much like  

  • that- only on the size of an entire planetAlso, it's not made of gold- but pure diamond.

  • PSR J171901438b, which we'll just  call 1438b for now if you don't mind,  

  • is without a doubt one of the strangest  objects in the sky. Also it's worth more  

  • than all the wealth generated by mankind in all  of history. But before you can even think about  

  • landing on a planet made out of diamondyou have to contend with its parent star.

  • This planet's star is actually a neutron star, or  the remnants of a supermassive star that could've  

  • been as much as 25 times the size of our own sunAt some point, this giant star blew its top in a  

  • massive supernova explosion, leaving behind its  superdense core. How dense? A single teaspoon of a  

  • neutron star's material would weigh a billion tons  here on Earth. Stray too close into this star's  

  • gravity field and you'll never leave it againso landing on 1438b is probably not an option.

  • Even if you did manage to land  on 1438b though, its parent star  

  • isn't done trying to murder you. That's  because its star is also a pulsar, or a  

  • neutron star that emits beams of concentrated  radiation so powerful, scientists at first  

  • believed pulsars to be alien navigation beacons  guiding their ships through intergalactic space.  

  • Most pulsars have a rotational speed of justfew seconds, washing everything in reach with  

  • intense radiation dozens of times a minuteHowever, millisecond pulsars make regular  

  • pulsars look like they're not even trying. These  stars can rotate in a matter of milliseconds,  

  • with the fastest recorded pulsar rotating in 1.6  milliseconds. 1438B's star isn't quite that fast,  

  • but it still rotates about 10,000 times per  minute, basically machinegunning the surface  

  • of 1438b with extreme radiation that even the  best shielded space suit won't save you from.

  • So you can basically forget about striking it rich  

  • with the Milky Way's very own El DoradoBut how did this diamond planet form?

  • Scientists believe that 1438b was once as large as  Jupiter, but had its outer layers blasted away by  

  • its pulsar parent star. The core of the planetprimarily composed of carbon, was left behind,  

  • which under extreme pressure would have  solidified to diamond or a diamond-like  

  • material. Given that any part of the  planet survived 1438b's parent star's  

  • supernova phase, it's likely that this  diamond planet was an extrasolar capture,  

  • flung out of orbit around its home system and  'caught' by the mighty pulsar that now guards  

  • its unfathomable riches. The universe is old,  

  • but our next duo of planets just might  be the youngest ever spotted by mankind.

  • 7. Baby Planets

  • The galaxy is an old place, about 13.5 billion  years or just 300 million years older than the  

  • universe itself. However, the Milky Way is  basically still an infant, and planetary  

  • formation is still an ongoing process that we canfor the first time, witness right here from Earth.

  • First imaged in 2018, PDS 70b and C were  identified as protoplanets shortly after  

  • their discovery. Planets are born from the  slow accretion of material surrounding a star.  

  • Electrostatic forces begin to clump up materialsimilar to the way static electricity can make  

  • your hair stand on end when you rub it with  a balloon. At a certain point, gravity takes  

  • over the attraction process and the planet-to-be  grows larger and larger as it pulls in more and  

  • more material towards itself. Once it has fully  cleared its orbital path of debris, the planet  

  • is considered officially 'born'- which is why  Pluto is not a planet anymore. Sorry, not sorry.

  • However, images of PDS 79b and C made it difficult  to actually see the planets in formation. That's  

  • thanks to the thick clouds of dust and  gas still surrounding the growing planets.  

  • Then in 2020 astronomers figured out a way  to image the planets through their star's  

  • interference and the debris that surrounded  them, giving humanity a baby picture of two  

  • Jupiter-like gas giants in formation and making  them some of the youngest planets ever discovered

  • Our next planet has scientists  buzzing with excitement,  

  • because it just might hold extraterrestrial life.

  • 6. Waterworld, Not Starring Kevin Costner

  • Not too long ago we used to think that  water, which is so abundant on our planet,  

  • was rare in the galaxy. Then we discovered  that our own solar system was lousy with  

  • it- even discovering it inside craters on  Mercury, the closest planet to the sun.  

  • If that wasn't enough, the discovery of GJ  1214b should end anyone's doubts that water  

  • is pretty abundant across the universe, which  is great news for the possibility of alien life.

  • Known as a 'waterworld', GJ 1214b is  believed to be completely covered by water,  

  • thanks to measurements of its density being  very close to the density of water. A thick,  

  • humid atmosphere envelops the  planet, which is somewhere in  

  • size between the Earth and Uranusand a lot cleaner than the latter.

  • GJ 1214b is believed to have formed far out from  its parent star where water ice was abundant,  

  • and then gradually pulled in closer to its star  where it rests now. Due to the abundance of water  

  • and scarcity of rock on this planet, scientists  predict we could discover all kinds of exotic  

  • materials such as 'hot ice' or 'superfluid water'. On our next planet temperatures get so hot  

  • that the clouds are made out of rock.

  • 5. Rock Atmosphere

  • You heard that right, our next strange planet has  an atmosphere made of rock. Well, vaporized rock.

  • Corot-7b was discovered way back in 2010, and  at the time was one of the smallest planets  

  • discovered. 70 percent larger than  the earth and 4.8 times Earth's mass,  

  • that still makes Corot-7b a pretty  big boy- or super earth. However,  

  • you can forget about Corot-7b being  super-habitable, because it's super-not  

  • unless you enjoy temperatures that can melt  steel and breathing in vaporized rocks.

  • 60 times closer to its parent star than the EarthCorot-7b experiences temperatures so extreme that  

  • its rocky core actually vaporizes into a thin  atmosphere, which is then inevitably blasted away  

  • by its sun. over the course of its lifetime, the  planet- which is believed to be the remnants of a  

  • saturn-sized planet- has had as much as several  earth masses of material already vaporized and  

  • blown away into space. A long time ago, Corot-7b  was likely much further away from its sun,  

  • but as it lost mass it migrated closer to its  sun, sealing its ultimate fate. Over time,  

  • the entire planet may disintegrate away  until no evidence of its existence is left

  • Our next planet is actually  hotter than some stars.

  • 4. Planet With Dreams Of Being A Star

  • At a certain point it gets very difficult to  tell the difference between a planet and a star,  

  • and no planet yet discovered pushes the boundaries  of that distinction quite like Kelt-9b. At twice  

  • the size of Jupiter, this massive planet is  already big enough to enter star territory,  

  • but its the incredible temperature of the planet  that really makes you consider if Kelt-9b is in  

  • fact, a planet. Receiving 44,000 times more energy  from its sun than we do from ours, Kelt-9b has a  

  • daytime temperature of 7,800 degrees (4300 C),  which is hotter than the surface of some stars

  • Tidally locked to its star, the way the  moon is to us, Kelt-9b is in a polar orbit,  

  • whizzing over it's star's poles every 36  hours. Given its rotation and orbital speed,  

  • Kelt-9b actually experiences two summers and  two winters per 36 hour 'year', with each season  

  • lasting just nine hours. For those viewers of  ours getting ready for summer break from school,  

  • imagine if your vacation only lasted a measly  four hours and be glad you don't live on Kelt-9b.

  • Also because, you know, you'd instantly be  vaporized by the star-like temperatures

  • Our next planet is without a doubtthe most beautiful ever discovered.

  • 3. If You Liked It You Should've  Put Several Thousand Rings On It

  • Saturn is the absolute crown jewel of the solar  system, with its beautiful ring system the planet  

  • is awe inspiring and never fails to wow every  time scientists release new photos of it. However,  

  • while Saturn may be the cock-of-the-walk in our  solar system, there's a planet out there that is  

  • overcompensating so hard, it makes Saturn look  like an intergalactic Walmart jewelry counter.

  • J1407b is a brown dwarf, or failed starthat's bigger than Jupiter. However,  

  • what's truly incredible about this planet is  the massive ring system that surrounds it,  

  • spanning out to a distance of 74 million  miles (120 million km)- or nearly 2/3  

  • the distance of the earth to the sunIt's ring system is 200 times larger  

  • than Saturn's and contains as much as an  entire Earth's mass in dust particles.

  • Astronomers have already identified one gap  in the massive ring system, which is almost  

  • certainly the formation of a moon somewhere in  size between the Earth and Mars. Over the next  

  • few million years this impressive ring system  will slowly fade from view as more moons form  

  • out of all the collected dust- which means if  humanity wants to see one of the most stunning  

  • sights in the universe for itself, it better start  inventing faster than light travel like yesterday

  • Our next planet was a candidate  for advanced alien life so good,  

  • that scientists immediately radioed  it hoping to make contact with E.T.

  • 2. Somewhere Between Heaven and Hell

  • In 2007 the discovery of Gliese 581c excited  astronomers and scientists around the world  

  • on the hunt for alien life. Only a few masses  larger than our own Earth, Gliese 581c is smack  

  • dab inside its star's habitable zone- meaning  that liquid water is possible on the surface.  

  • With such similarities, surely there's a  good chance Gliese 581c may be habitable.

  • However, closer examinations of this planet  revealed that it was tidally locked to its  

  • parent star, and orbits so close that the  daytime side would be a scorching hellscape,  

  • while the night time side would be a frozen  wasteland. However, along a thin band of  

  • terrain between the two extremes, where  the land is bathed in a perpetual sunset,  

  • temperatures are believed to be moderate enough to  allow liquid water, and thus life. Unfortunately  

  • the huge temperature differences would mean that  weather would be very extreme on Gliese 581c,  

  • so if life does exist it better have some way of  withstanding hurricane-force winds every single  

  • day. This would not bode well for technologically  advanced life, though SETI scientists beamed  

  • a hello message to the planet anyways, which  won't reach any potential listeners until 2029. 

  • Our number one planet is so weird, it  basically turns everything you know  

  • about physics upside down. 1. A Place Where Ice Burns

  • Ice. We're doing our damn best to make  it extinct on our own planet's oceans,  

  • but still enjoy it in cool summer drinks. However,  

  • put some ice from Gliese 436b in your cup  and you'll instantly boil your drink away,  

  • pretty promptly followed by your cup and  hand. That's right, on Gliese 436b ice burns.

  • Wait, what? Gliese 436b orbits its parent star in  

  • just over 2 days, which means it either violates  all the laws of physics or is very, very close to  

  • its star. Given that planets are so far obedient  to physics, the safe deduction is that Gliese  

  • 436b is as close to its sun as one-thirteenth the  distance from Mercury to our own sun. This puts  

  • surface temperatures at an estimated 980 degrees  (526 C), well above the boiling point of water.

  • Despite this, Gliese 436b is believed to  have an icy covering around its rocky core,  

  • with the ice so hot that it would  incinerate any refrigerator you  

  • tried to put it in. If ice as hot as  the devil's balls is strange to you,  

  • it was strange to scientists too who theorized  that the ice remained solid due to the incredible  

  • gravity of the planet compressing water  vapor in its atmosphere into solid form.
