The sun attracts the moon with a force twice as large as the attraction of the earth on the moon. Why does the moon not revolve around the sun?

It’s crazy to see how many wrong answers were posted for this question. "The Moon indeed revolves around the Sun."

The Moon revolves neither around the Earth nor around the Sun.

The Earth and the Moon revolves around their common center-of-mass. Since the Earth is much heavier than the Moon, this point is inside the Earth, but it’s not in the middle.

The Earth also does not revolve around the Sun. The common center-of-mass of the Earth and the Moon has a common center-of-mass with the Sun. So the Sun and the common center-of-mass of the Earth and the Moon revolves around their common center-of-mass.

At least in case you forget about the rest of the planets in the system. (And the rest of the Universe.)

In general, nothing revolves around something else by gravity. They revolve around each other.
