A new study has revealed that gravity’s effect on Earth is constantly shaping the surface of our planet. When our planet formed, it did so by pulling dust and rock toward its gravitational field.

Its surface gravity is 37.5 percent of Earth’s. Mars rotates on its axis every 24.6 Earth hours, defining the length of a Martian day, which is called a sol (short for “solar day”).

Some objects fall differently depending on how gravity and air resistance interact. A feather, for example, is light and has a large surface area, meaning it will fall to the ground slowly.
