I thought it was time to split the subject from the Moon forum.
Admins, can you move the relevant messages here? anyway, just out: an interesting blog article by Bill Gray explaining how he recovered the probe and how he computed the orbit yielding the 13 December flyby date Chang'e 2: The Full Story |

According to JPL's HORIZONS ephemeris service,
(Some of) The vital statistics of Toutatis on the 13th December 2012 are as follows: Epoch (UT) () Geocentric distance () Apparent Magnitude () Solar Elongation () (AU) () () (deg) 13/12 00:00 () 0.0466 () 10.73 () 125 13/12 12:00 () 0.0471 () 10.65 () 128 14/12 00:00 () 0.0478 () 10.59 () 132 Toutatis will be east of the sun and so an evening object in the sky. Judging from the magnitude and solar elongation, I would say that it is well within reach of backyard observers (including myself). Regards to All, Tolis. |
