Mars has an observed synodic period S of 780 days, or 2.1355 years. How long it takes Mars to complete one full orbit of the Sun?
 
Mars orbit is larger than Eath’s orbit, so it is a superior planet.
Mathematical relation for superior planet’s sidereal period and synodic period is
Relating Synodic and Sidereal Periods
where: P – Superior planet’s sidereal period
E – Earth’s sidereal period = 1 year
S – Superior planet’s synodic period
mars sidereal period
mars sidereal period
P = 1.881
P = 1.9 years
It takes 1.9 years for Mars to complete one full orbit of the Sun.
