Re: Super Earth with a radius and an atmosphere
“Being so close to its host star, the planet must have a surface temperature of about 200 degrees Celsius, too hot for water to be liquid,â€
Total NONESENSE. The critical point of water is 647 K (374 C). All you need is more pressure, and a 200km-thick steam atmosphere will have quite some pressure!
