IM not makeing any sense?
ME?
so when does ISON finish an orbit, and return?
Quoting: Shadow Beam It's not returning, it's hyperbolic, that's what it means. It does not mean you "don't know." that is not what Hyperbolic means. Hyperbolic means a comet has an eccentric orbit and MAY not return. this because its full orbit is not known there is no condition of the word hyperbolic that defines a comet WILL NOT return on an orbit path this is the case with ISON as its origin and start date of current orbit are unknown. please contest this fact with a reply to my other question what is the origin of ISONs current orbit? "In astrodynamics or celestial mechanics a hyperbolic trajectory is a Kepler orbit with the eccentricity greater than 1. Under standard assumptions a body traveling along this trajectory will coast to infinity, arriving there with hyperbolic excess velocity relative to the central body. Similarly to parabolic trajectory all hyperbolic trajectories are also escape trajectories. The specific energy of a hyperbolic trajectory orbit is positive. The shape of a hyperbolic trajectory is a hyperbola." [ link to en.wikipedia.org] oh right comets follow orbits a completion of a cycle but not ISON it came from nowhere and is heading for infinity!! science ay! solves all unresolved subjects
