Quizplus · Accepted Answer

An astronaut's weight on another planet will depend on the mass and radius of the planet. The strength of the planet's gravitational field will determine how much the astronaut weighs. If the planet has a smaller mass and radius than Earth, the gravitational pull will be weaker and the astronaut will weigh less. If the planet has a larger mass and radius than Earth, the gravitational pull will be stronger and the astronaut will weigh more. Therefore, the answer is D, any of these choices, depending on the planet.
