Question

jamesj · Answer

What are Kepler's laws?  That's what you need for this problem.

Yes I know that. I'm guessing I would also need the mass of the sun, the equaion related two masses m1 and m2 to gravity and the distance between the earth and the sun?

jamesj · Answer

The earth rotates the sun every 1.0 years.  Use Keplers laws to find the mean distance of the Comet as a multiple of the earth's orbit.  Then multiple that number by the earth's orbit in kms.
