What is Parabolic trajectory?
In [[astronomy]], a '''parabolic trajectory''' (also known as parabolic [[orbit]] or parabolic [[Escape velocity|escape trajectory]]) refers to an object (such as an [[asteroid]]) which follows a path similar to a [[parabola]] around another object. This motion follows [[Kepler's Laws]]. A parabolic trajectory occurs when the [[Orbital eccentricity|eccentricity]] of its orbit is equal to 1. Other types of motion in [[astronomy]] include [[circular orbit]], [[elliptical orbit]], and [[hyperbolic trajectory]]. {{science-stub}} [[Category:Orbits]]
