<blockquote><font class="small">In reply to:</font><hr /><p>The one thought to have been Apollo 12 was sighted in 2002 and as such, was merely seen passing.<p><hr /></p></p></blockquote><br /><br />Actually, it was in Earth orbit when it was sighted. It was observed a number of times, enough to determine its orbit, and learn that it had only been in Earth orbit a short while; it had passed through the Sun-Earth-L1 point to be recaptured by Earth's gravity. I believe it has since passed through the L1 point again, departing the Earth system for a while. It will likely continue to be captured by the Earth and lost again for a long time. (It is believed to have departed the Earth system original via the same route. L1 is a sort of gravitational portal between heliocentric and geocentric influence.) <div class="Discussion_UserSignature"> <p> </p><p><font color="#666699"><em>"People assume that time is a strict progression of cause to effect, but actually from a non-linear, non-subjective viewpoint it's more like a big ball of wibbly wobbly . . . timey wimey . . . stuff."</em> -- The Tenth Doctor, "Blink"</font></p> </div>
