Tempel 1 (official designation: 9P/Tempel) is a periodic Jupiter-family comet discovered by Wilhelm Tempel in 1867. It completes an orbit of the Sun every 5.6 years. Tempel 1 was the target of the Deep Impact space mission, which photographed a deliberate high-speed impact upon the comet in 2005.

2024年11月3日 · Comet 9P/Tempel 1 orbits the Sun within the asteroid belt, which lies between the orbits of Mars and Jupiter. Tempel 1 last reached perihelion (closest approach to the sun) in 2016. Tempel 1 is a Jupiter-family comet.

Tempel 1 is a short-period comet, meaning that it moves around the Sun in an elliptical orbit between the planets Mars and Jupiter in a relatively short time. It was the ninth periodic comet to be recognised as such, hence the 9P.

On the night of April 3, 1867, at Marseilles Observatory in France, Wilhelm Tempel discovered a ninth-magnitude comet near the star Zubeneschamali, in the constellation of Libra, the Scales.

Comet 9P/Tempel 1 was discovered on April 3, 1867 by Ernst Wilhelm Leberecht Tempel of Marseille, France while visually searching for comets. The comet was then 9th magnitude and described by Tempel as having an apparent diameter of 4 to 5 arcmin across.

Comet Tempel 1 is most famous for being the target of the 370 kg impactor probe deployed from the NASA Deep Impact mission in July 2005 when the comet was near perihelion.

9P/Tempel 1 is a mid-sized comet whose orbit features a relatively short period, low inclination, and is controlled by Jupiter's gravitational effects. NASA JPL has not classified 9P/Tempel 1 as potentially hazardous because its orbit does not bring it close to Earth.

Comet 9P/Tempel 1 is a periodic Jupiter-family comet discovered by Wilhelm Tempel in 1867. It completes an orbit of the Sun every 5.5 years. Tempel 1 was the target of the Deep Impact space mission, which photographed a deliberate high-speed impact upon the comet in 2005.

2019年1月30日 · This spectacular image of comet Tempel 1 was taken 67 seconds after it obliterated Deep Impact’s impactor spacecraft. The image was taken by the high-resolution camera on the mission’s flyby craft.

2011年2月14日 · Just one year before its Feb. 14 encounter with comet Tempel 1, NASA's Stardust spacecraft performed the largest rocket burn of its extended life. With the spacecraft on the opposite side of the solar system and beyond the orbit of Mars, the comet hunter's rockets fired for 22 minutes and 53 seconds, changing the spacecraft's speed by 24 meters ...
