Characteristic energy
text:
In astrodynamics, the characteristic energy is a measure of the excess specific energy over that required to just barely escape from a massive body. The units are length2 time−2, i.e. velocity squared, or energy per mass. Every object in a 2-body ballistic trajectory has a constant specific orbital energy ϵ equal to the sum of its specific kinetic and specific potential energy: where μ = G M is the standard gravitational parameter of the massive body with mass M , and r is the radial distance fr
