Talk:Escape orbit

Can anyone give a derivation of the simple formula for the position as a function of time?
 * Equations for the position as a function of time for radial escape trajectories can be found at:The radial Kepler problem

The (uncited) definition of an escape orbit is inconsistent with prevailing use. It is common knowledge that escape trajectories can be either parabolic or hyperbolic.

The content of the page is specific to radial parabolic orbits, not escape orbits. It should be merged with radial trajectory.

Should "Escape Orbit" be left as stub, a disambiguation page, or moved to Wiktionary? --Norbeck (talk) 13:30, 20 January 2010 (UTC)
