When moving away from the source it is called an escape orbit, otherwise a capture orbit. It is also sometimes referred to as a C3 = 0 orbit (see Characteristic energy). lanky pankyWeb5. Orbit Characteristics We have shown that the in the two-body problem, the orbit of the satellite about the primary (or vice-versa) is a conic section, with the primary located at the focus of the conic section. Hence the orbit is either an ellipse, parabola, or a hyperbola, depending on the orbit energy and hence eccentricity. assimilation norskWebThe other two parameters are the eccentricity, which you can see right here. Eccentricity of course shows you how eccentric it is. Eccentricity ranges from 0 if you're a circular orbit all the way up to 1 if you're on a parabolic orbit.
