The Planet Mars and its Satellites The equatorial radius of Mars is 3 397 000 m, about half that of the earth, and its dynamic flattening f is 1/192, so it is more oblate than the earth, but still an approximate sphere. (G = 6.67 × 10-11 Nm2-kg-2) The radius of Mars is 3.39 x 106 meters and its mass is 6.43 x 1023 kg. The geometric flattening was quoted as 1/77, but the discordance and the reason for it has not been mentioned lately. The picture below shows the planets in their orbits on the orbital plane. As it is 14% of radius of Neptune, this means that if Mars' radius is 14%, Neptune's radius is 100%. Conversely, a person is 62.17% heavier on earth than on Mars. The planet's atmosphere is very thin. It is a periodically conspicuous reddish object in the night sky. Radius of Mars is 3396.2 km. Deimos is 23,460 km (14,580 mi) from Mars, much further than Mars's other moon, Phobos. This is thought to be because of the blood-red color of the planet which was also used by other ancient cultures.

F = m * a. F = G * m * m[o] / r[o]^2. 1% is 3396.2/14 km. The most fuel efficient way to enter an areosynchronous (same as geosynchronous, but Mars) would be to do a close pass of Mars to orbit, burning until the apoaerion is at the areosynchronous orbital height, and then burn again to have it be at a true areosynchronous orbital plane. Deimos / ˈ d aɪ m ə s / or / ˈ d i m ɒ s / (systematic designation: Mars II) is the smaller and outermost of the two natural satellites of Mars, the other being Phobos.Deimos has a mean radius of 6.2 km (3.9 mi) and takes 30.3 hours to orbit Mars.

Unlike our own planet, whose internal structure has been well defined, our knowledge of the interior of other planets in the solar system is as yet very limited. a = G * m[o] / r[o]^2. Therefore, a person would be much lighter on mars. Named after the Roman god of war, it is often described as the “Red Planet”, as the iron oxide prevalent on its surface gives it a reddish appearance. A.
