Artist’s conception of the K2-360 system (IMAGE) National Institutes of Natural Sciences Caption Artist’s conception of the K2-360 system, showing the ultra-dense super-Earth K2-360 b (red) in its extremely close orbit around its Sun-like star, with the more distant companion K2-360 c (blue) in the background. The scorching temperatures on K2-360 b, which completes an orbit in just 21 hours, likely result in a molten or partially molten surface.
