These are bodies in orbit (around each other) due to the forces of gravity.
If the barycenter (the point around which both rotate) of the system is inside one of the bodies (such as the Sun and any of the planets as well as the Earth and Moon system) then the less massive body is said to orbit the more massive one.
If the barycenter is in space between the bodies it is called a binary system or double planet (such as Pluto and Charon)
A natural body that revolves around a planet is called a moon. Moons are celestial objects that orbit planets as a result of gravitational attraction. They vary in size and composition, and can have significant effects on their host planet.
The word is "planet." A planet is a large body that revolves around the sun, and a planetarium is a place where individuals can observe and learn about celestial bodies, including planets.
A moon is an object that revolves around a body larger than itself, typically a planet.
A natural satellite, or a moon.
Orbit is the term used to describe the curved path that a planet follows as it revolves around another body, such as a star. Orbits are typically elliptical in shape, with the body being orbited located at one of the foci of the ellipse. Orbits are governed by the gravitational pull between the two bodies, with the more massive body at the center of the orbit.
Objects such as moons or satellites that revolve around a planet are typically referred to as "natural satellites" or "moons." Artificial satellites placed in orbit around a planet are simply called "satellites."
