The most common type of orbit is a circle but depending on the size, mass, density of that planet and the orbit of others but the orbit so far found by Astromoners and Scientists alike are all circle based.In there title don't you mean What is the movement of earth and the other eight seven planets and many dwarf planets around the sun?
This is called an "exhibit" or a showing.

Actually Dwarf planets are planets which are very small in size and cannot be called planets but not as small to be called asteroids, so the name dwarf planets.
They are sometimes called minor planets (not mirror planets).They aren't planets really, but they are a bit like little planets orbiting the Sun.
