Why is the moon not affected by the sun’s gravity, but seemingly affected strongly by the earth’s gravity?

In: Physics

It is. The earth, however, is a lot closer to the moon than the sun is. Gravity drops by the square of the distance, so despite the suns massive size it simply is too far away to have a very distinguishable effect on the moon in comparison to the somewhat large, fairly close by earth.

The moon ***is*** affected by the sun’s orbit in the same way the earth is. After all, the moon orbits the sun with the earth.

However, the moon is more than 400 times closer to the earth than it is to the sun, so – keeping in mind that gravity drops of proportionally to the square of the distance – it stands to reason that earth has a proportionally larger impact on the moon.

The Moon is affected by Sun’s gravity.

Earth orbits Sun. Moon orbits Sun.

Or in more words the common center of mass of Earth + Moon is orbiting Sun. Both Earth and Moon have slightly wiggly orbits but since Earth is so much more massive than Moon the center of mass is pretty close to Earth and Earth wiggles less. https://en.wikipedia.org/wiki/File:Orbit3.gif
