Question

practice it!
the earth orbits the sun because the suns gravity pulls on it.
why does the moon orbit the earth and not the sun?
the moon is actually much closer to the sun than it is to the earth. therefore, the moon is orbiting the sun and the earth happens to be in its path.
the moon is much closer to the sun than it is to earth. the gravity from the sun is stronger than the gravity from the earth at that distance. so the moon orbits earth, not the sun.

Explanation:

To determine why the Moon orbits Earth and not the Sun, we analyze the options:

• The Moon is much closer to Earth (average ~384,400 km) than to the Sun (average ~150 million km). Gravitational force depends on distance (inverse - square law) and mass. Even though the Sun is more massive, the Moon’s proximity to Earth means Earth’s gravity at the Moon’s location is stronger than the Sun’s gravity there.

Let’s evaluate each option:

1. First option: Incorrect. The Moon is closer to Earth, not the Sun.
2. Second option: Incorrect. The Moon is closer to Earth, not the Sun.
3. Third option: Incorrect. If the Sun’s gravity were stronger at the Moon’s distance, the Moon would orbit the Sun (but it doesn’t, and Earth’s gravity is stronger at that distance).
4. Fourth option: Correct. It states the Moon is closer to Earth, Earth’s gravity is stronger at that distance, so the Moon orbits Earth.

Answer:

The Moon is much closer to the Earth than it is to the Sun. The gravity from Earth is stronger than the gravity from the Sun at that distance. So the Moon orbits Earth, not the Sun.
