planet in the solar system.

Weight

Explanation: The weight of an object is different on every planet in the solar system. Weight is the gravitational pull of an object towards the surface of a planet. It is measured in Newtons, using a spring balance. Weight changes from one place to another depending on the gravitational acceleration of a surface. For example, the weight of an object on the surface of the earth is different from the weight of the same object on the surface of the moon. Mass of an object, on the other hand, remains constant and is the same on every planet in the solar system.
