The very fact that a celestial body has mass gives it gravity, but that gravity’s strength depends on how heavy the object is.

Mars is smaller than Earth – its diameter is about half ours. Mars is also less dense. Therefore the planet is about a tenth as heavy as Earth. Mars has gravity, but its pull is only about a third of that on Earth.
