parabola
parabola A type of curve whose ‘arms’ become parallel as they approach infinity, so that the curve never quite closes in on itself, defined mathematically as a
conic section with an eccentricity of 1. It may be regarded as an ellipse in which the two foci are infinitely far apart, and is the limiting case between an ellipse and a hyperbola. Some comets have elliptical orbits that are so extended they are indistinguishable from parabolas.
