An orbit is the path that an object takes as it moves around another object in space due to gravity. For example, the Earth orbits the Sun, taking about 365 days to complete one full revolution. This movement is not a perfect circle but an ellipse, which means the distance between the Earth and the Sun changes slightly throughout the year.
In addition to planets, many other objects can have orbits, such as moons that circle planets and satellites that orbit the Earth. These orbits are essential for understanding how celestial bodies interact and help scientists predict events like eclipses and the positions of stars.
