Questions regarding an object 'falling around' another object, due to a combination of gravity and momentum.
An orbit is the trajectory a body follows due to the gravitational field of another nearby object. Most often, an orbit follows a closed path and is periodical, but the term can also refer to non-repeating trajectories.
Examples of orbits include the path of the Moon around the Earth, the path of the Earth around the Sun, or the path of two stars in a binary pair around their common center of mass.
