An alien planet located 202 light-years away from Earth has a truly hellish environment where winds of 5,000 km/h blow and rocks are poured into a 100 km-deep lava sea, according to a study.
The place where McGill University, York University and the Indian Institute of Science and Education jointly simulated the planetary environment was K2-141b, an alien planet discovered in 2018. This planet is located 202 light-years from Earth, orbits in 0.3 days, has a radius of 1.5 times that of Earth and 5 times the mass of Earth.
As a result of analyzing the solar pattern of K2-141b by the research team, it was found that the Earth repeats day and night in a 12-hour cycle, but in K2-141b, two-thirds of the surface is always daytime. In addition, it is said that the daytime temperature is 3,000 degrees Celsius, and at night-200 degrees Celsius.
A temperature of 3,000 degrees Celsius thickly melts rocks containing sodium, silicon monoxide, and silicon dioxide, so it is believed that a sea of lava spreads in K2-141b. In addition, as there is a cycle in which water evaporates and condenses and rains on Earth, in K2-141b there is a cycle in which rocks evaporate at a high temperature of 3,000 degrees Celsius and condensate and rain at night by the wind of 5,000 km/h.
However, the K2-141b cycle was not as stable as the water cycle on Earth. By repeating dissolution and condensation, the mineral content in K2-141b will change, and ultimately the planet’s surface and atmosphere will change completely.
The research team said that the atmosphere of K2-141b spreads beyond the lava sea, and of course, among all the dark planets including the earth, initially it was a world where lava seas were spreading, but afterwards, lava planets such as K2-141b were rapidly cooled and solidified. Explained that it is a rare being to show. The research team plans to observe the K2-141b in more detail using the James Webb space telescope scheduled for October 2021.
