Geodesic Data from Mars
Mars gravitates on a highly eccentric orbit with an average distance of 228 million km from the Sun. Its diameter is two times smaller than Earth and its mass is ten times less important. In addition, the Martian year (period of revolution of the planet around the Sun) is about two terrestrial years (687 days), while the average Martian days (period of rotation of the planet itself) is close the duration of our day (24h40 min). |
