This is how Comet Hartley 2 might appear in the eyepiece of a large amateur telescope. Located about eight degrees (16 full moon diameters) away from the bright star Procyon as it leaves the constellation Gemini, Comet Hartley will be best viewed high in the sky just before dawn.

Comet Hartley 2 and Earth's Ocean Water

Measurements from the Herschel Space Observatory show that comet Hartley 2, which comes from the distant Kuiper Belt, contains water with the same chemical signature as water in Earth's oceans. The findings may help explain how Earth’s surface ended up covered in water.

Malcolm Hartley discovered Comet Hartley 2 back in 1986. On Nov. 4, NASA's Deep Impact spacecraft will make a close flyby of the comet, coming within a mere 435 miles (700 kilometers).

Hubble Space Telescope observations of Comet 103P/Hartley 2, taken on Sept. 25, 2010, are helping in the planning for a Nov. 4 flyby of the comet by the Deep Impact eXtended Investigation (DIXI) on NASA's EPOXI spacecraft.
