Шаблон:Short description Шаблон:Infobox Comet

10P/Tempel, also known as Tempel 2, is a periodic Jupiter-family comet with a 5 year orbital period. It was discovered on July 4, 1873 by Wilhelm Tempel.[1] The next perihelion passage is 2 August 2026 when the comet will have a solar elongation of 164 degrees at approximately apparent magnitude 8.[2] Closest approach to Earth will be one day later on 3 August 2026 at a distance of Шаблон:Convert.[3]

The comet nucleus is estimated to be roughly the size of Halley's Comet at 10.6 kilometers in diameter with a low albedo of 0.022.[3] The nucleus is dark because hydrocarbons on the surface have been converted to a dark, tar like substance by solar ultraviolet radiation. The nucleus is large enough that even near aphelion (furthest distance from the Sun which is near the orbit of Jupiter) the comet remains brighter than about magnitude 21.

During the 2010 apparition the comet brightened to about apparent magnitude 8.[2] The most favorable apparition of 10P/Tempel 2 was in 1925 when it came within Шаблон:Convert of Earth with an apparent magnitude of 6.5.[1]

Proposed exploration

The Jet Propulsion Laboratory proposed a flyby of the comet with a flight spare of Mariner 4.[4] The probe was instead used for a Venus flyby as Mariner 5.[4]
