Orbit of Mars
Orbital parameters
No more than five significant figures are presented in the following table of Mars's orbital elements. To this level of precision, the numbers match very well the VSOP87 elements and calculations derived from them, as well as Standish's (of JPL) 250-year best fit, and calculations using the actual positions of Mars over time.
