Though circle is a simple geometry but the planets are kept in their orbits by a central force i.e. gravitation. Central forces are any force that follows inverse square law of distance. Now, by using really great partial differential mathematics, it can be proved that for orbiting in the influence of any central force, the orbit must be elliptical in shape.

Its due to inertia of the planet.
