    Mass of orbiting body calculations

    Now I understand - thank you. So what would prevent a large planet like Jupiter from having an orbit as small as Mercury?

    Mass of orbiting body calculations

    Sorry, yes, that was my question. I wanted to calcualte the weight of an orbiting body knowing its period and radius. So if the body in question does not have a moon how else would it be calculated?

    Mass of orbiting body calculations

    Ok, so I did have the mass of the sun calculated correctly as 1.98 E+30 but I was thinking of the orbiting body. It has been years since I did this math. What formula would I use?

    Mass of orbiting body calculations

    Ok, so I am tryting to calcualte the mass of an orbiting body. I am using M = 4 * PI^2 * r^3 / ( G * T^2 ) Lets use the Earth as an example. However I am not getting what Nasa has for answers of 5.9 E24 kg. http://nssdc.gsfc.nasa.gov/planetary/factsheet/earthfact.html Using this...
