The sun's gravitational pull keeps the earth in orbit around it.
There is no gravity in space but the shuttle stays in orbit because of the Earths gravity and inertia. The inertia keeps it going in a circular motion. In space the Earth's gravity is strong enough to hold something in orbit but not strong enough to pull it to Earth's surface.
gravity pulls the earth into position so it doesn't move away and gravity is what holds us down onto the earth as well.
Because the moon moves with a certain speed in its orbit, that orbital motion produces a centrifugal force which opposes the attraction of gravity. The balance between gravity and centrifugal force keeps the moon in orbit. The moon continues to orbit at the speed it does, because of its inertia. Moving in the vacuum of space, the moon does not encounter resistance to its motion. There is, however, some energy lost as a result of tidal forces, and that will, over a very long period of time, eventually alter the moon's orbit.
The Earth's spin, or rotation on its axis gives us a day.

Gravity and Inertia keeps the earth in orbit
The force that keeps the moon in orbit around the Earth is gravity. Specifically, the gravitational pull between the Earth and the moon is what keeps the moon in its elliptical orbit.

gravity
earth's gravity
gravity and inertia combine to keep earth in orbit because the suns gravity keeps the earth in orbit and the inertia keeps the earth from going in a straight line.
The Sun
The earth is six times more massive than the moon. That keeps the moon in orbit around it, just as the mass of the sun keeps the earth in orbit around it.

The gravitational force.
The balance between the inertia of the Moon and the gravitational pull keeps the moon in orbit with Earth.
The moon keeps moving in its orbit around the Earth due to its inertia and the gravitational pull of the Earth. There is a balance between the moon's velocity and the gravitational force that keeps it in a stable orbit.
