planet K2-18 b, located in the constellation Leo at a distance of about 124 light-years from Earth, may be much more habitable earth-like than previously thought. After the cosmic object was discovered in 2015, for a long time it was considered a “mini-Neptune” with a thick hydrogen shell, where you can hardly see the life. However, experts at Cambridge University have built a computer model that allows you to reconsider this idea.
Experts suggest that K2-18 b, orbiting a red dwarf, two and a half times the Earth radius in eight-and-a-half times by volume. It is in the habitable zone of its star, i.e. the water in it can stably exist in the liquid form, and, judging by the abundance of water vapor in the atmosphere, this substance presented there in sufficient quantities.
the Study was published in the journal Astrophysical Journal Letters.
