Comet 103P/Hartley in Perseus - a photo on Flickriver

            This is a picture of Comet 103P/Hartley. It was very faint - too faint for me to get the tail but I did get the fuzzy glow of the comet.

What I had wanted to find was the new comet discovered by Hideo Nishimura on 12 August 2023, but it was below the horizon. As it turns out there are other comets slicing through our solar system right now and I got this one.

Comet Hartley 2, designated as Comet 103P/Hartley is a small periodic comet with an orbital period of 6.48 years. It was discovered by Malcolm Hartley in 1986 at the Siding Spring Observatory, Australia. Its diameter is estimated to be 1.2 to 1.6 kilometres.

Hartley 2 was the target of a flyby of the Deep Impact spacecraft, as part of the EPOXI mission, on 4 November 2010, which was able to approach within 700 km.
