The search for new planets, stars, and life outside the solar system led scientists to discover the weirdest planets in the universe. The recent discoveries baffled the world on how extraordinary the universe can be. Some of the planets are so unique that it made headlines when it was discovered.
Here are five unique exoplanets found outside the Earth’s galaxy:
Made with water
The GJ1214 has a lot of water than the solid material.Scientists discovered the planet in December 2009. According to scientists, the planet is a literal water world, completely covered with ocean. The full name of the planet is Gliese 1214 b or GJ1214. The planet’s parent star is 42 light-years from the Earth’s sun, in the constellation Ophiuchus.
In 2015, the planet is mostly known as the ocean planet. Scientists nicknamed the planet the water-world. The GJ 1214 is significantly bigger than Earth but smaller than the gas giants of the solar system.
The 55 Cancri e is a literal diamond in the sky. Its shortened form is the 55 Cnc e. The 55 Cancri e, a.k.a. Jansenn is an exoplanet orbiting its sun-like host called star55 Cancri A. The mass of 55 Cnc e is around 8.63 Earth masses, while its diameter is twice of the Earth. Scientists discovered the planet on August 30, 2004.
With its size twice than the Earth, scientists identified it as the first super-Earth. In October 2012, scientists announced that the 55 Cancri e might be a carbon planet. The planet is made of carbon-rich material than the oxygen-rich material in the Earth’s solar system. Since the more than a third of the planet’s man is made of carbon, it caused the formation diamond. The planet’s temperatures and pressures caused the creation of the diamonds on its surface.
A planet of burning ice
The Gliese 436 b is an oxymoron of itself. The exoplanet has a small rocky core while an icy exterior covering the majority of the planet. The planet’s size is comparable to planet Neptune. It orbits the red dwarf called Gliese 436. The planet was the first hot planet discovered in 2007. In December 2013, NASA reported that they might have detected clouds in the planet’s atmosphere.
The distinction of the planet is its ‘hot ice’ feature. It has various exotic and high-pressure forms. It has a burning temperature of 439 degree Celsius. The ‘ice’ remained solid despite the high temperature due to the planet’s gravity.
