WebAn orbit is a repeated path that an object (known as a satellite) takes around another object. The planet Earth orbits the Sun, along with the other planets in our solar system. … WebThey take account of three variations in the orbit of the earth around the sun. The earth’s orbit changes from being nearly circular to slightly elliptical (eccentricity). This cycle is affected by other planets in the solar system and has a period of around 100,000 years.
