Why there is no atmosphere around many planets then why does earth has atmosphere?
Is the distance from the Sun also a factor?
Yes, distance from the Sun plays a role in determining whether a planet can sustain an atmosphere. Planets that are too close to their star, like Venus, can have extremely hot atmospheres that escape into space, while planets that are too far from their star, like Mars, can have very thin atmospheres because of the low temperatures they experience.
