Mars orbit is larger than Earth's orbit, so it is a superior planet. Mathematical relation for superior planet's sidereal period and synodic period is Relating Synodic and Sidereal Period is \frac{1}{p}=\frac{1}{E}-\frac{ 1}{s} where: P: Superior planet's sidereal period E: Earth's sidereal period =1 year s : Superior planet's synodic period
\frac{1}{p}=\frac{1}{1}-\frac{1}{2.1355}=0.5317 P = 1.9 years It takes 1.9 years for Mars to complete one full orbit of the Sun
