Mars's radius would be a measly 86.4 miles (139 km), meaning it would be unable to maintain its hydrostatic equilibrium.
The radius of the moon would be 588.7 miles (947.4 km).
Mars is. Mars has a mean radius of 3397km while our moons mean radius is 1737km.
The average radius of Mars is about 3,389.5 kilometers.
The average radius of Mars is about 2,106 miles (3,389 kilometers).
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.
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.

The surface area of Mars is approximately 144,798,500 square kilometers. The equatorial radius is about 3,396 km and the polar radius is 3,376 km.
Obviously there is no sea, so for for Mars, the zero elevation is defined by the mean martian radius, 3382.9 kilometers, and the [average] atmospheric pressure [which] is 6.1 millibars.
The Earth's radius is6 378.1kmSo that means that the earth is 1.88 (almost 2) times larger.
