What is Circular orbit?
In [[astronomy]], a '''circular orbit''' refers to an object (such as a [[planet]] or a [[star]]) which [[Orbit|orbits]] around a central body in a fixed, [[Circle|circular]] motion. This motion follows [[Kepler's Laws]]. A [[Circle|circular]] [[orbit]] occurs when the [[Orbital eccentricity|eccentricity]] of its [[orbit]] is equal to 0. Objects with a [[Circle|circular]] [[orbit]] are uncommon. The [[Moon]] moves in an [[elliptical orbit]] around the [[Earth]], and the [[Planet|planets]] move in an [[elliptical orbit]] around the [[Sun]]. Other types of motion in [[astronomy]] include [[elliptical orbit]], [[parabolic trajectory]], and [[hyperbolic trajectory]]. {{science-stub}} [[Category:Orbits]]
