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. 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. If gm is the acceleration due to gravity at the surface of Mars, what is the acceleration due to gravity at the location of the satellite? The planet is named after Mars, the Roman god of war. a = G * m[o] / r[o]^2. Therefore, a person would be much lighter on mars. You are allowed to answer only once per question. The radius of Mars is about 3400 km, and its moons Phobos and Deimos orbit 9600 km and 23,500 km from the center of the planet. As it is 14% of radius of Neptune, this means that if Mars' radius is 14%, Neptune's radius is 100%. The four inner planets (Mercury, Venus, Earth and Mars) are in the tiny disk in the center, inside of Jupiter's orbit. As a result, it experiences a bulge at its equator which leads to a variation of 40 km (25 mi) between its polar radius and equatorial radius. These are approximate driving distances in a radius from Mars Hill, North Carolina. The radius of Mars is 53% of the radius of Earth, and its mass… It is mostly carbon dioxide with some argon and nitrogen and tiny amounts of other gases including oxygen.The temperatures on Mars are colder than on Earth, because it is farther away from the Sun and has less air to keep heat in. The orbital velocity of a planet relative to that of Earth's is then the relative radius divided by the relative length of the year. The planet's atmosphere is very thin. Here's the table: Planet Radius (km) Mercury 2,440 Mars 3,397 Jupiter 71,492 Thank you so much for your help! Mars is the fourth planet from the Sun and the second smallest planet in the Solar System. There are many towns within the total area, so if you're looking for closer places, try a smaller radius.
