The planet’s mean orbital velocity is 24.2 km/sec, and the period of revolution around the sun (sidereal period) is 1.881 years (687 days). Mars, the sun, and the earth align in a straight line once every 780 days (synodic period). The time elapsing between successive oppositions of ...

Because of the rotation period of Mars, the view of the planet changes slightly from night to night. Mars rotates in the same direction as Earth every 24 hours and 37 minutes, just a little longer than the rotation period of Earth. If you observe Mars with a correct view with north up ...
