In Earth's case, its orbit is nearly circular, so that the difference between Earth's farthest point from the Sun and its closest point is very small. Earth's orbit defines a two-dimensional plane which we call the ecliptic.The Earth with its Sun.he Earth's orbit is in the shape of an ellipse, so that sometimes the Earth is a little bit closer to the Sun than at other times.
Orbits 'R' Us! When we talk about how Earth and the other planets travel around the Sun, we say they orbit the Sun. Likewise, the moon orbits Earth. Many artificial satellites also orbit Earth. When it comes to satellites, space engineers have different types of orbits to choose from.Satellites can orbit Earth's equator or go over Earth's North and South Poles. . . or anything in between.They orbit at a low altitude of just a few hundred miles above Earth's surface or thousands of miles out in space.
