WebJun 27, 2013 · So I'm going to stick with calling it a "Martian geostationary orbit." Mars is considerably less massive than Earth (it has about 11% of Earth's mass) but rotates at about the same angular rate, so a stationary orbit at Mars will be smaller than one at Earth. The Martian geostationary orbit altitude is only 13,634 kilometers (so an orbital ... WebFor an ellipse, recall that the semi-major axis is one-half the sum of the perihelion and the aphelion. For a circular orbit, the semi-major axis ( a) is the same as the radius for the orbit. In fact, Equation 13.8 gives us Kepler’s third law if we simply replace r with a and square both sides. T 2 = 4 π 2 G M a 3.

Well, 365 days is about how long it takes for Earth to orbit all the way around the Sun one time. A year is measured by how long it takes a planet to orbit around its star.
