Mars's radius would be a measly 86.4 miles (139 km), meaning it would be unable to maintain its hydrostatic equilibrium.

False. In volume, Mars is 0.15 times the volume of earth. Mars' radius is roughly half of Earth's radius.


How far is Mars from Phobos?

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.
