Orbit Meaning and Definition in Wikipedia


An orbit is the path that an object takes in space when it goes around a star, a planet, or a moon. It can also be used as a verb. For instance: “The earth orbits around the Sun.” The word ‘revolves’ has the same meaning, but 'rotates' is the spin of the object.

Many years ago, people thought that the Sun orbits in a circle around the earth. Every morning the Sun came up in the east and went down in the west. It just seemed to make sense that it was going around the earth. But now, thanks to people like Copernicus and Galileo Galilei, we know that the Sun is the center of the Solar System, and the earth orbits around it. Isaac Newton discovered that gravity controls the orbit of the planets and moons. Since a satellite is an object in space that revolves around another object, the earth is a satellite of the sun, just like the moon is a satellite of the Earth! The sun has lots of satellites orbiting around it, like the planets, and thousands of asteroids, comets, and meteoroids. The Earth just has one natural satellite (the Moon), but there are many artificial satellites orbiting the earth.
