Question

Why do Earth and the moon remain in orbit?

Answer 1

Answer:

because of gravitional force(gravity)........

Answer 2

In normal Newtonian physics, it is usually considered that the Moon revolves around the Earth. With a lower mass, the Moon is affected by the Earth’s gravity more than the Earth is affected by the Moon. The two bodies orbit around the barycenter, a point of gravitational equilibrium approximately 3/4 of the Earth’s radius from the center of the planet.

The motions of these celestial bodies depend on your point of reference, and the mass of the bodies. The Earth, Moon, Sun, and the other planets are traveling in eccentric paths around the center of the Milky Way Galaxy, which is itself moving relative to the other galaxies in the vicinity.
