Frost and Fire - Gliese 436 b (Exoplanet) - In the constellation of Leo 33.1 light years away, a Neptune-sized planet orbits a red dwarf star at a distance of 4.3 million kilometres—15 times closer than Mercury is to our sun. It’s no surprise that the planet, Gliese 436 b, has an incredibly hot surface temperature of 439 degrees Celsius, but it’s definitely a surprise that the planet is also covered in ice. Since the boiling point of water is 100 degrees Celsuis,
exoplanet Gliese 436 b has a tail. It is located at a distance of 33 light years from Earth, and its mass comparable to the mass of Neptune. Presumably Gliese 436 b is composed of water, and its atmosphere - helium. The tail is formed by hydrogen evaporating from the atmosphere due to too close to the orbit of the star. exoplanet period of rotation around its star just 2.6 days.
Astronomers have found a star with an incredibly low concentration of heavy elements that still has a sizable planet around it — the most metal-poor star ever discovered with an orbiting, rocky planet.
The University of Central Florida has detected what could be its first planet, only two-thirds the size of Earth and located right around the corner, cosmically speaking, at a mere 33 light- years away. The exoplanet candidate called UCF
