Want this question answered?
I'm pretty sure that gravity and inertia cause something to orbit around another object.
Gravity and Inertia.
An orbit is made possible by an equilibrium, or balance, of forces. Typically, this involves two forces: one of gravitational attraction between the objects and another caused by centripetal acceleration. At a given radius of orbit, a velocity can be found such that these two forces are equal, keeping the object in orbit.
Gravity, which pulls an object inward, and inertia, which resists gravity. They combine to form a more-or-less circular orbit.
Orbits are established by the combined effects of gravitational attraction and relative velocity. In other words, the moon, like any orbiting body, moves forward (tangent to its orbit) at a speed just sufficient to ensure that as it falls toward the earth due to gravity, it has moved far enough that the two motions combine to keep it at a roughly stable distance from the earth.

Rotation- the spinning of earth about its axis Revolution- movement of earth in its orbit around the sun :)

A tangential velocity vector relative to the orbit itself, and acceleration towards the center of the planet due to gravity.
Velocity and gravity (movement around the Earth and the gravity of the Earth pulling on it).

The Earth is in orbit round the Sun, but also the Sun is moving round the centre of our galaxy, and of course we follow along.
The two motions that Earth makes are rotations and revolutions.
The two motions of Earth are ;- Daily (24 hours) axial rotation. Annual (1 year) orbital (revolution) about the Sun. NB There are several other known movements of the Earth. they are ;- The angle of the Earth's axis varies between 28 degrees to 21 degrees. Currently at 23 degrees. The Earth's orbit about the Sun is an ellipsoid, that is an ellips that doesn't quite close up with each orbit, but slightly overlaps. This elliptical movement varies between nearly circular to a narrow ellipse. The Earth speeds up an slows down through space, because the Sun lies at one of the foci of the ellipse , NOT the centre. As a consequence, when nearer the Sun we moive faster, and when further away we move slower. Because of the Moon , the Earth 'wobbles' in and out of its orbital track. Summing , we can say that the Earth 'dances' through space, with the Sun and Moon as partners.
Those two things do not really combine so the answer is nothing causes it.
No, it is two.
