===Meaning===
An [[orbit]] is the [[circle|circular]] or [[ellipse|elliptical]] path that an [[object]] takes a more [[mass|massive]] [[object]] due to a [[force]] of attraction acting between them.
===About Orbits===
: [[Orbit]]s are caused by a [[force]] of attraction between two [[object]]s acting towards their centres.
: [[Planet]]s [[orbit]] [[Star]]s due to the [[force]] of [[gravity]].
: There are two types of [[orbit]] you should know:
:*Circular [[orbit]] - An [[orbit]] where the distance between the two [[object]]s (the [[radius]]) remains constant. In this [[orbit]] the [[speed]] of the [[orbit]]ting [[object]] is constant. However, the [[velocity]] of the [[orbit]]ting [[object]] is constantly changing due to the changing direction.
:*Elliptical [[orbit]]
