Homework Help: Difficult gravitational potential problem

  1. Oct 30, 2005 #1
    I dont even know where to start:
    Assume the earth's oribt about the sun is circular. Calculate the work required to launch a 1kg probe into the earth's orbit around the sun, but on the opposite side of the orbit.

    Is the satellite launched from earth's surface? Then there would be work getting it to orbit - and then to escape velocity.

    I suppose the rest would be how much thrust (and over what distance) is used getting the satellite into opposition from the earth.

    That approach does not include the gravitational influence of the sun, or am I completely missing the point?
