Multiple choice

Which of the following does NOT influence the gravitational acceleration acting on a planet?

  1. The mass of the star it orbits

  2. The mass of the planet itself

  3. The gravitational constant, G

  4. The distance from the star it orbits

B Correct answer
Explanation

Gravitational acceleration on a planet's surface is determined by the planet's mass and radius (g = GM/r^2). The mass of the star it orbits does not affect the surface gravity of the planet itself.
