    Dear Max,

    No, Kepler first used Mars as a reference point to obtain the figure of the Earth's orbit - and only then (having better precision of Earth's positions) attempted to find the form of the Mars's orbit. Mars has more prominent ellipticity in its orbit than Earth.

    Regards,

    Tony
