Explanation:
Detailed explanation-1: -Also, if you are closer to the Sun, the atmosphere is hotter and the molecules are moving faster and so can reach escape velocity. This is why Mercury has no atmosphere, but much smaller and colder Pluto can still retain a thin atmosphere.
Detailed explanation-2: -Mercury is the closest planet to the Sun in our Solar System. Due to this, the planet has no atmosphere.
Detailed explanation-3: -Atmosphere and Weather: Mercury has an extremely thin and non-protective atmosphere. For all practical purposes, the atmosphere is nearly a vacuum.
