Just someone making a comment on the radio saying
QUOTE = He did it and it did come back ?
Outside or Inside they didn't say.

lol What an image
If the object has the same mass as you, and your initial velocity is 0. If it has a much lower mass, it will do many orbits and pass you several times before you do one. Thrown at a tangent to your orbit, I would also expect the radius of the object's orbit to consequently become somewhat greater than the thrower's own orbit.As both you and the object are doing great circles your paths will cross twice per orbit.
I presume you mean 180 degrees (by the way, how do make the degree symbol?)? Thrown at 90 degrees and a tangent to the orbit, and given the variables related to momentum I've already mentioned, it's most likely that the orbits of the object and the thrower will never simultaneously intersect.If you were in space and threw anything, boomerang, spanner, feather etc, at 90° to your direction of travel then you will meet it again on the other side of the earth.

That doesn't seem to work. Maybe because I'm on my laptop?alt+0176

i seriously doubt that...
i mean, I wouldnt let an astronaut fat enough to have his own gravitational force onto a shuttle w/ me. space travel is difficult enough without having to have a separate physisist crunching numbers to accomodate for one side of the shuttle being a half ton heavier than the other. lol
