05. Why is there a difference of gravitational forces between planets? (A K2S Question)

From The Space Library

Each particular planet's gravitational force is a combination of the product of the two masses and the square of the distance between them. So, for example, Jupiter is a high-mass planet with a large diameter and has a relatively large gravitational force. If Jupiter were the same mass, but smaller diameter, the gravitational field at the surface would be even larger.
