The escape velocity from the surface of an object depends on the object's mass and radius. This is because these two factors determine the gravitational force on the surface of the object and the distance over which it needs to be overcome to escape. The escape velocity is given by the formula: Vesc = √(2GM/r), where G is the gravitational constant, M is the mass of the object, and r is its radius.
