orbital period

Orbital period is the time it takes for an object, like a planet or satellite, to complete one full orbit around another object, such as a star or planet. For example, Earth's orbital period around the Sun is about 365 days, which is a year. This period depends on the distance between the two objects and their masses; the farther or less massive the orbiting object, the longer it takes to complete its orbit. Essentially, the orbital period measures how long an object takes to go around its partner once.
