There are several examples of objects that orbit celestial bodies other than the Sun. Here are a few notable ones:
Moons: Moons are natural satellites that orbit planets or dwarf planets. For instance, Earth has a natural satellite called the Moon, while other planets like Jupiter, Saturn, Uranus, and Neptune have numerous moons. These moons orbit their respective planets due to gravitational forces.
Artificial Satellites: Human-made objects called artificial satellites are launched into space and placed in orbits around various celestial bodies. Examples include satellites that orbit the Earth, such as those used for communication, weather monitoring, scientific research, and navigation (e.g., GPS satellites).
Asteroids and Comets: Some asteroids and comets can have moons of their own. For instance, the dwarf planet Pluto has multiple moons, including Charon. Similarly, certain comets can have smaller objects orbiting them, known as comet nuclei or comet companions.
Binary Star Systems: In binary star systems, two stars orbit around a common center of mass. Each star revolves around the other due to their gravitational interaction. This means that both stars orbit each other, rather than one star orbiting the other.
Exoplanets: Exoplanets are planets that orbit stars outside our solar system. These planets can have various types of orbits around their host stars, similar to how planets in our solar system orbit the Sun.
These are just a few examples of objects that can orbit something other than the Sun. The universe is vast, and there are numerous fascinating orbital configurations and interactions among celestial bodies.
