Comet 103P/Hartley in August 2010

Comet Hartley 2, officially designated 103P/Hartley is a small periodic comet with an orbital period of 6.46 years. It was discovered by Malcolm Hartley in 1986 at the Schmidt Telescope Unit in Siding Spring, Australia. Its diameter is estimated to be 1.2 to 1.6 km.

There is a planned flyby of Hartley 2 by the Deep Impact spacecraft with a closest approach of 700 kilometers on November 4, 2010. This is part of the EPOXI mission.

The comet will pass within 0.12 AU of the Earth on October 20 2010, which is only eight days before coming to closest approach to the Sun on October 28, 2010. During this passage, the comet may be visible to the naked eye at apparent magnitude 5 in the constellation Auriga, if you know where to look and are viewing from a dark sky location.
