The radius of the moon would be 588.7 miles (947.4 km).
Mars's radius would be a measly 86.4 miles (139 km), meaning it would be unable to maintain its hydrostatic equilibrium.
Mars is. Mars has a mean radius of 3397km while our moons mean radius is 1737km.
Because the acceleration of gravity on the surface of any given body depends on the mass of the body and its radius ... the distance of the surface from the center. Mars' mass ... about 11% of Earth's ... and Mars' radius ... about 53% of Earth's ... combine to produce about 38% of Earth's gravitational acceleration at the surface of Mars.
Venus is BIGGER then Mars.Venus has a diameter of 12,104 km where as Mars is only 6,787 km.Venus is bigger than Mars. Venus is the sixth biggest planet in our Solar System and Mars is the seventh.
The equatorial radius 3,396.2 kilometers (2,110miles).The equatorial circumference of Mars is 21,339 kilometers (13,259 miles).Compared to Earth, the ratio is .533, i.e. the radius and circumference of Mars is about half the radius and circumference of Earth.
False. In volume, Mars is 0.15 times the volume of earth. Mars' radius is roughly half of Earth's radius.
is mars the third hottest planet
9,377 km on average. 9,377km is the average of the periapsis and apoapsis of Phobos' orbit around Mars. But aren't the apses measured from the gravitational focus which would be near the center of Mars. If that is true, then the equatorial radius of Mars of 3396km should be subtracted from 9377km which would give an approximate distance of 5981km. Of course, Phobos also has a radius of 11km, so the distance between the surface of Phobos and the surface of Mars would be approximately and on average about 5970km. Yes that is the correct answer. 5970 km on average from the surface of Mars.
The percent of water that is found on Mars is only 2 percent. The surface of Mars is mainly dry which is marked by old volcanoes.

Mean radius = 3390 km Equatorial radius = 3396 km Polar radius = 3376 km.
With a radius of 3396km, the planet Mars is about the same size as the inner and outer core of the earth (which is around 3490km radius in total).
