Both objects orbit around their common center of mass.
For both the sun-earth case, and the moon-earth case, the large body is so much more massive
than the small one that their common center of mass is inside the larger one. So in both cases,
it would look like the smaller one is orbiting the larger one.
But if you had two 12-pound Bowling balls doing a gravitational orbit on a lazy Saturday afternoon
outside the window of the Space Shuttle, you'd see both of them circling the point half-way
between them.
An orbit around another orbit is called a "satellite orbit" or a "suborbital path". This occurs when a smaller object orbits around a larger object, which is itself in orbit around another celestial body.
Orbit: as in the Earth orbits round the Sun.
Celestial orbit refers to the curved path that an object in space, such as a planet or satellite, follows around a larger celestial body, typically a star. This orbit is determined by the object's velocity and the gravitational pull of the larger body it is orbiting.
If you take a mechanical model of the solar system, grab the earth; then the sun will orbit it and the planets will "adopt" a elliptical orbit. However; observations of extra-solar system planets show that stars are stationary, except for a slight "wobble" as they ACTUALLY orbit their COMMON center of gravity which is VIRTUALLY near the star given it's having the bulk of the mass, thereby giving the impression of it being PERFECTLY stationary relative to a satellite. But; of the underlying physical mechanism whereby a larger object remains central there must be a "stay put" factor to it's superior "spinning power" even as a spinning top has the tendency to "stay put" whilst it is doing so. Whether this phenomena is describable in physics I don't know. Incidentally, the physics of the gyration of a spinning top, and also the similar precision of the equinoxes on earth is UNKNOWN and a great mystery in science.
An orbit, which is an ellipse.
An orbit is the circular or elliptical motion of one smaller body around another larger body due to gravitational attraction.
This is an orbit.
The barycenter. The barycenter of the Earth - Moon system is inside the Earth about 2000 kilometers beneath the surface. The Barycenter of the Charon - Pluto system is in space between those celestial bodies.
An orbit is created when an object is moving at a high enough speed to counteract the gravitational pull of another object, such as a planet or star. The object's velocity and direction must be balanced so that it continually falls toward the larger object while also moving sideways fast enough to avoid crashing into it. This balance results in a stable path around the larger object, forming an orbit.
An orbit is the path that an object takes around another object in space, like a planet orbiting a star. An orbital, on the other hand, refers to the specific region around an atom where an electron is likely to be found. Orbits are larger and more defined paths in space, while orbitals are smaller and more specific areas within an atom.
"orbit"
An object kept in orbit is typically influenced by the gravitational pull of a larger object, such as a planet or a star. The object's velocity and direction must also be balanced to prevent it from either falling into the larger object or flying off into space.
