Especially hot planet discovered

4300 degrees.

The temperature is so high because the planet is very close to its star. There is no water, carbon dioxide or methane, because the star's UV radiation is too intense. Life is therefore completely impossible. Because of the heat the planet is evaporating. The KELT-9b probably has a 'tail' of its own material.

One year, the period the planet needs for a round around its star takes only one and a half days.
