The path traveled by a body in space is known as an orbit.
An orbit is the path an object follows as it moves around another body or point under the influence of gravity. Earth follows an orbit around the Sun, the Moon follows an orbit around Earth, and artificial satellites can orbit planets, moons, or other astronomical objects.
Although diagrams often show neat circles, real orbits are commonly elliptical, or oval-shaped. Johannes Kepler described the elliptical orbits of the planets in the early 17th century, and Isaac Newton later explained them through his theory of gravity. An object's speed can also change along its orbit: it generally moves faster when closer to the body it circles and slower when farther away.
Orbit is sometimes confused with trajectory. A trajectory can mean the overall path of a moving object, including one that escapes into space or falls back to Earth. An orbit specifically describes a gravitationally bound path that repeatedly goes around another object or location. The International Space Station, for example, travels in low Earth orbit.
