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. It was re-visited by the Stardust spacecraft on February 14, 2011.  It has dimensions 6.3 x 5.9 x 5.2 km, a very slow rotation period of 40.7 hr, and an orbit semi-major axis distance of 3.145 AU with an eccentricity of 0.5096.

The Rosetta mission was launched on March 2, 2004. It was to do a detailed study of comet Churyumov-Gerasimenko. It was the first spacecraft to orbit a comet, and to have a lander on a comet.

INTERNATIONAL ROSETTA MISSION

The goal of the Deep Impact mission was to understand the physical and chemical properties of a comet as a function of depth below the surface.   The mission delivered an impactor spacecraft onto the nucleus of 9P/Tempel 1. It was launched on January, 12, 2005.
