According to the giant impact hypothesis, Theia orbited the Sun, nearly along the orbit of the proto-Earth, by staying close to one or the other of the Sun-Earth system’s two more stable Lagrangian points. Theia was around the size that Mars is now.
Theia was eventually disturbed away from that relationship by the gravitational influence of Jupiter, Venus, or both, resulting in a collision between Theia and Earth - forming our Moon.
Our Moon is unusually large for the size of our planet, and is positioned to the same area as the Sun in our sky - a coincidence resulting in total solar eclipses occurring on our planet.
