67P/Churyumov-Gerasimenko, shortened 67P or 67P/C-G, also known as Rosetta's comet, is a Jupiter-family comet originally from the Kuiper belt.

It is orbiting the Sun within a period of 6.44 years in a distance between 1.24 and 5.68 AU, getting as close as between Earth's and Mars' orbit at its perihelion while its aphelion lies somewhat outside the orbit of Jupiter.

History
