WebOct 9, 2008 · Orbital periods are also given in units of the Earth's orbital period, which is a year. The eccentricity (e) is a number which measures how elliptical orbits are. If e = 0, the orbit is a circle. Most of the planets have eccentricities close to 0, so they must have orbits which are nearly circular. Last modified October 9, 2008 by Randy Russell. WebJan 22, 2016 · Motions of Mars Mars follows an elliptical orbit about the Sun. The orbital semimajor axis of 1.5237 AU and eccentricity of 0.0934 give a perihelion distance of q = a (1 – e) = 1.3814 AU and an aphelion distance of Q = a (1 + e) = 1.6660 AU. The inclination of the orbit of Mars is a modest 1.85°.
