Our Exoplanets is a site about exoplanets that we think are very interesting, like Kelt-9B or GJ 1214B. These planets are very different from Earth and extremely strange. Today we only focus on certain exoplanets, because there are too many to do everything. We have selected a few that interested us and we hope they will interest you too. Say no to plagiarism.

Hot Jupiters are not known for their hospitality, as they are extremely hot, have poisonous air, and the possibility of rains of flesh-melting metal. But the hottest of all is Kelt-9B, which is almost three times the weight of Jupiter and KELT-9b orbits its star every 18 hours. Which means you could celebrate a birthday every day and sometimes even have 2! But a planet this close to a star is likely tidally locked, keeping one hemisphere always facing its star. Its star's barrage of ultraviolet energy roasts KELT-9b like a marshmallow, bringing its daytime temperature to around 4600°K (7820.33°K). F/4326.85°C), which is hotter than the surfaces of many stars. Elements such as carbon dioxide, water and methane cannot form at such high temperatures on the day side, although it is possible that they can form on the night side of the planet. Additionally, overheating on KELT-9b's day side caused it to swell. Even though KELT-9b is almost three times the weight of Jupiter, its density is only half as much. KELT-9b is the hottest gas giant discovered, but it is not the hottest planet. Its full name being Gliese 1214B, this exoplanet is entirely covered in water. GJ 1214B is located about 40 light years from Earth in the constellation Ophiuchus. This so-called “Super-Earth” measures about 2.7 times the diameter of Earth and weighs almost seven times more than our Earth. It orbits a red dwarf star at a distance of 1.2 million mi (2 million km), giving it an estimated surface temperature of 503.15°K (230°C/446°F) . GJ 1214b appears to contain much more water than Earth. done, and much less land. The interior structure of the planet is most likely different from that of Earth. The high temperatures and pressures would form exotic materials like “superfluid water.” Scientists assume that at the bottom of the ocean, the pressure will create ice 7, a type of ice that is not cold.

Get a Custom Essay Also known as Scorpion-1b, this exoplanet orbits HD 131399A, part of the triple star system HD 131399. It is 340 light-years from Earth in the constellation Centaurus. The planet is approximately 16 million years old. Its temperature is around 850°K (577°C/ 1,070°F). It is estimated to weigh 4 times the mass of Jupiter. The planet marks the first discovery of an exoplanet made with SPHERE, which stands for Spectro-Polarimetric High-Contrast Exoplanet Research Instrument. It is installed on the Very Large Telescope. SPHERE is sensitive to infrared light, making it capable of detecting the heat signatures of young planets, as well as features that correct atmospheric disturbances and block the otherwise blinding light of their host stars..
