10P/Tempel, also known as Tempel 2, is a periodic Jupiter-family comet in the Solar System. It was discovered in 1873 and has an orbital period of 5.3 years.[7]
The comet nucleus is estimated to be 10.6 kilometers in diameter with a low albedo of 0.022.[6] The nucleus is dark because hydrocarbons on the surface have been converted to a dark, tarry like substance by solar ultraviolet radiation.
During the 2010 apparition the comet brightened to about apparent magnitude 8.[1] It next comes to perihelion (closest approach to the Sun) on 14 November 2015 when it should brighten to around magnitude 11.[1]
The most favorable apparition of 10P/Tempel 2 was in 1925 when it came within 0.35 AU (52,000,000 km; 33,000,000 mi) of Earth with an apparent magnitude of 6.5.[8] On August 3, 2026, comet Tempel 2 is expected to have another close pass within about 0.41 AU of Earth.[9]
