text: Mercury moves faster than the Earth as it travels around the Sun; however, Mercury has a highly elliptical orbit, so the speed of its orbit changes.
text: It also has an elliptical orbit which, although not as elliptical as Pluto's, is very marked, as the closest it gets to the Sun (its perihelion) is 46 million km while the furthest it ever gets (its aphelion) is 70 million km.
text: Because Mercury has an elliptical orbit around the sun--compared with Earth's circular orbit--and because it has such a slow rotation, this makes the sun appear to move in a way that people from Earth would find highly unusual.
