Much like the Earth and the Moon , KELT-9b is to its star; with one side of the planet always exposed to its star. Due to tidal locking, the planet's surface temperature facing the star is roughly 4300°C (7772°F), more than the surface temperature of an average Red Dwarf star. Its close proximity to its parent star exposes it to ultraviolet radiation, and according to the calculations, the planet loses planetary material anywhere between ten billion to ten trillion grams each second. Professor Gaudi said, "It's a planet by any of the typical definitions of mass, but its atmosphere is almost certainly unlike any other planet we've ever seen just because of the temperature of its dayside".
