Top 10 Strangest Planets in Our Known Universe



Our universe can be a bizarre and terrifying place, but it’s fascinating nonetheless. In light of this, we’ve compiled a list of the 10 strangest planets that will really get you thinking. Get ready to open up your mind and take an adventure into outer space.

Number Ten: TrES-2b. A whole 750 light years from space, TrES-2b is the darkest planet that we currently know of. It reflects less than one percent of the light that hits it. It also glows red and is the hottest planet in our known universe.

Number Nine: 55 Cancri e. Known as the diamond planet, one third of 55 Cancri e is made of solid diamond. Considering it’s twice the size of earth, bringing back just a tiny fraction of this planet’s diamond would have a monstrous effect on the industry here on earth.

Number Eight: Gliese 436 b. Gliese 436 b really puts the concept of “fire and ice” to the test. Though the planet is technically a giant ball of ice, it is constantly burning. The ice is able to remain solid thanks to the strength of the planet’s gravity.

Number Seven: HD 1897733b. How would you like to live on a planet that constantly rains glass? Well, allow us to introduce you to HD 18977 3b. Though its blue atmosphere appears welcoming, it is actually due to a pouring down of molten glass – sideways, no less.

Number Six: WASP-12b. WASP-12b is slowly being eaten alive, thanks to the fact that its orbit is extremely close to its parent star. Though this may make you think WASP-12b is puny, it is actually roughly the size of Jupiter (the largest planet in our solar system).

Number Five: Gliese 581 c. Voted one of the top three exoplanets likely to support alien life, Gliese 581 c orbits a red dwarf star. However, it doesn’t rotate on its axis, meaning that one side is very, very hot, and the other is very, very cold. The only habitable section is on its side.

Number Four: WASP-17b. Nearly twice the size of Jupiter, WASP-17b is known as a “puffy planet” due to its large radius and low density. Theoretically, the planet should not exist, but there are no laws in space! Perhaps it has something to do with its retrograde orbit.

Number Three: HD 188753 Ab. What makes HD 188753 Ab special are its parent stars. This lucky planet has not one, but three parent stars! This means that there are many eclipses – not to mention absolutely breathtaking sunsets, like the one depicted above.

Number Two: GJ 1214b. Throw him to the fishes! Or, in this case, throw him to GJ 1214, because this planet is made entirely of water. Interestingly, its core is covered in a dense coating of special ice, called ICE VII. This ice is not made from freezing, but rather due to the intense pressure of the planet’s surrounding water.

Number One: Kepler 438b. Perhaps the most well-known planet on this list, Kepler 438b was discovered in January of 2015¬†and is the most earth-like planet researchers have ever found. On what’s called the Earth Similarity Index, Kepler ranks 0.88; considering the scale goes from zero to one, where zero is completely unlike earth and one is earth itself, that’s pretty impressive.
