Moon and Mars have less gravity, so they have no atmosphere.

That's part of it, sure, but they also don't have a magnetosphere, which blocks the solar radiation from blasting away the atmosphere.

Mars used to have a thicker atmosphere, but the lack of a magnetosphere meant it eventually blew away.
