10 planets exist that you won’t believe
10.OGLE-2016-BLG-1195Lb
The Iceball Planet
OGLE-2016-BLG-1195Lb is an icy exoplanet that can be found a whopping 13,000 light-years from our solar system. Its temperatures range from -220 degrees Celsius (-364 °F) to -186 degrees Celsius (-302 °F), which is why it’s sometimes called the “iceball planet.”
09.KELT-9b
The Hot One
KELT-9b is the hottest exoplanet ever found, and it’s disappearing! At 650 light-years away from us, KELT-9b is tidally locked with its star, meaning that one side is constantly facing the star and one side is not.
The gas giant is approximately three times the size of our Jupiter and burns at a temperature of 4,315 degrees Celsius (7,800 °F). This is hotter than most stars and almost as hot as the surface of our Sun, which burns at 5,505 degrees Celsius (9,941 °F).
08.GJ 1214b
The Steamy Waterworld
GJ 1214b is a huge “waterworld” three times the size of Earth that can be found 42 light-years away from our solar system. Earth’s water is equal to 0.05 percent of its mass, while GJ 1214b’s water contributes 10 percent of its mass!
GJ 1214b is thought to have oceans that may reach depths of as much as 1,600 kilometers (1,000 mi). In contrast, the deepest part of our own oceans is the Mariana Trench, 11 kilometers (7 mi) deep.
07.PSR J1719-1438 b
The Diamond Planet
PSR J1719-1438 b is a planet made of pure diamond!
A large, carbon-based planet with a diameter roughly five times that of Earth, PSR J1719-1438 b can be found about 4,000 light-years away from our solar system. Due to immense pressure caused by the planet’s gravitational pull, the carbon has been condensed, forming a gigantic diamond.
06.Kepler-16b
The Real-Life Tatooine
Kepler-16b is essentially the real-life equivalent of the Star Wars planet Tatooine. This is because Kepler-16b is one of the only exoplanets ever found that orbits a binary star system.
Kepler-16b has the mass of about 105 Earths and is 8.5 times the radius of our world. This exoplanet has an atmosphere comprised of hydrogen, methane, and small amounts of helium. Approximately 200 light-years away from our solar system, Kepler-16b completes an orbit around its two stars in 627 of our Earth years.
05.Kepler-10b
The Scorched World
Kepler-10b is the smallest exoplanet discovered to date, and we believe that the surface is covered by oceans of lava. About 560 light-years away from Earth, Kepler-10b was the first rocky planet found outside our solar system, marking mankind’s first step toward a future of space exploration.
The surface reaches temperatures as high as 1,400 degrees Celsius (2,500 °F).As a result, rocks on the surface melt, pooling in large areas and causing huge lava oceans scattered across the exoplanet’s small surface. Due to its high density, it’s believed that Kepler-10b contains a high amount of iron, which would cause the lava to appear a brighter shade of red.
04.TrES-2b
The Dark Planet
TrES-2b is the darkest exoplanet ever found, reflecting less than 1 percent of the sunlight that hits it. This makes it darker than coal or black acrylic paint. It’s actually a miracle that we found the planet because the light was so scarce.
This raises an important question: How many exoplanets have we missed due to the lack of light?
TrES-2b is about 750 light-years away from our solar system. Its atmosphere contains vaporized sodium, potassium, and titanium oxide—all of which absorb light. However, it is still a mystery as to why the planet is so dark, a mystery that may never be solved.
Perhaps an alien race inhabits this strange planet and we just don’t know about it.
03.HD 189733b
The Planet That Rains Glass
Perhaps one of the most interesting exoplanets on this list, HD 189733b, which is 63 light-years away, rains glass.Sideways. Yes, you heard that right. This hellish planet’s winds can reach speeds of up to 8,700 kilometers per hour (5,400 mph), causing any strange precipitation to fall sideways.
A silica-concentrated atmosphere causes the planet’s clouds to rain molten glass, which hardens as it falls. HD 189733b’s wind pushes the glass at such speeds that the shards fly through the air horizontally, slicing up everything in their path. Imagine getting stuck in that storm!
02.55 Cancri e
The Planet With Weird Water
55 Cancri e is tidally locked with its sun and has water on its surface that is both a liquid and a gas. This exoplanet orbits 25 times closer to its star than Mercury does to our Sun and completes its orbit in only 18 hours. That’s extremely fast.
Since 55 Cancri e is tidally locked with its star, one side constantly faces the sun and the other does not. As a result, the water facing the star is in a supercritical state, causing it to be both a liquid and a gas at the same time.
55 Cancri e has mass of around 7.8 times that of Earth, and it is roughly twice our planet’s size.
01.CoRoT-7b
The Planet That Snows Rocks
CoRoT-7b is a bizarre exoplanet because it snows rocks!
Like many other exoplanets, it is tidally locked with its star. The side facing the sun reaches temperatures as high as 2,200 degrees Celsius (4,000 °F), while the other side drops to as low as -210 degrees Celsius (-350 °F).
Lava on the star side is heated so much that it evaporates much like water does on our planet. This creates large stone clouds that later condense on the relatively cooler side of the planet, where it rains large rocks. If we could survive the extreme temperatures of this planet, it would be a sight to see.
