**tchrwill**, Sunday, November 13, 2011 at 4:04pmEscape velocity derives from Ve = sqrt[2µ/r] where Ve = escape velocity in ft/sec., µ = the gravitational constant of the earth and r = the surface radius.

µ can also be stated as GM where G = the gravitational and M = the mass of the planet.

Therefore, Ve can be simply expressed by

Ve = sqrt[2(13)µ/(r/13)] = sqrt[169(2µ/r] =

13 times earth's escape velocity of Ve = 36,747fps = 25,054mph or 325,712mph.

V(new)/V(earth) = 13
