If the Astronaut threw a mass in exactly the same line of his orbit, they would meet again eventually, but the Astronaut would be long dead from lack of air. Assuming the astronaut threw a 30 MPH pitch with the mass, it would have to circumscribe a circle much larger than the circumference of the earth, at a speed of 30 MPH. It would be more than 35 days before the object made it back around. If the course of the object deviated from the "orbit line" in the slightest, the chances of the two ever meeting again are, uh, astronomical. -- - Sean Casey UUCP: {cbosgd,anlams,hasmed}!ukma!sean - Department of Mathematics ARPA: ukma!sean@ANL-MCS.ARPA - University of Kentucky
