10 Most Bizarre Planets You’ve Probably Never Heard Of

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.

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!

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.

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.

On the hotter side, it rains magma. On the colder side, the magma hardens before hitting the ground (much like snow does on Earth). This creates rock snow that would kill you if you happened to be in its presence.
