Comet 81/P WIld
Comet 81/P Wild

Comet Wild 2 is a short periodic comet with an orbital period of 6 years. Before its close encounter with Jupiter during September 1974 his orbit was almost circular and had a 43 year period. But the gravitational pull of the giant gas planet made Wild 2 to a member of the inner solar system. In 2004 the comet was target of the NASA mission "Stardust", which took samples of the coma and returned them back to earth. Our image was obtained during a trip to southern france in February 2010 and shows a nice 1 degree long tail.

2004 EU22

... is an apollo-class NEO. It was was discovered by LINEAR on 15 March 2004 and had its closest approach to earth on the same day at a distance of 0.0132 AU or roughly 5 lunar distances. On 17 March 2004 at 21:00 we were able to pick it up in the constellation Leo. The NEO was moving at a speed of 22"/min. So the exposure time was limited to 10 seconds for a single frame.

Three series of 18 images were stacked with Astrometrica. The temporary designation AM37068 was changed to 2004 EU22 after five other observatories reported astrometry to the MPC.
