along a parabolic trajectory can be computed as: v = 2 μ r {\displaystyle v={\sqrt {2\mu \over r}}} where: r {\displaystyle r} is the radial distance of the...

compared to the enormous eccentricity of Halley's Comet and Eris. A radial trajectory can be a double line segment, which is a degenerate ellipse with semi-minor...

A trajectory or flight path is the path that an object with mass in motion follows through space as a function of time. In classical mechanics, a trajectory...
