Hi all! I've made a spreadsheet that helps me plan my missions. I just went to Moho, established a polar orbit and turned on my Mapsat. While waiting I noticed that my circular orbit velocity calculation does not match the orbit speed KSP reports. I checked my calculations again, tested them with Kerbin and Eve, 100% correct.. I suspect something wrong with the Wiki numbers regarding Moho. The "Constant of Gravitation" is of course correct... (6,67259E-11) This means that the mass of Moho in the Wiki (3.6747079E+21) cannot be correct (or have I misunderstood something?). I'm at 100km orbit around Moho. KSP reports 694,1m/s. My spreadsheet suggest 836,04m/s. If KSP speed is right, Moho has a mass of about: 2,527E+21 This is quite different from the Wiki.. I'm no rocket scientist, can anyone shed some light on this? EDIT: From some more calculations, it could also be that the radius of Moho actually is around 207600m (I think??) Thanks!
