Important support for general relativity came from studies of the precession of the orbit of Mercury
A route that an object in space follows around another is known as an orbit. A satellite is a thing that orbits the earth. An Earth- or moon-like natural satellite is one possibility. Moons are satellites that orbit many planets. A man-made satellite is also possible, such as the International Space Station.
Albert Einstein created the gravitational theory known as general relativity between 1907 and 1915. According to general relativity theory, the apparent gravitational pull between masses is caused by the bending of spacetime caused by those masses.
