67P/Churyumov–Gerasimenko (abbreviated as 67P or 67P/C–G) is a Jupiter-family comet. [10] It is originally from the Kuiper belt [ 11 ] and has an orbital period of 6.45 years as of 2012, [ 1 ] a rotation period of approximately 12.4 hours, [ 9 ] and a maximum velocity of 135,000 km/h (38 km/s; 84,000 mph).

Greyscale photograph of Comet Churyumov–Gerasimenko taken by the Rosetta mission. Comet Nucleus Dust and Organics Return (CONDOR) is a mission concept to retrieve a sample from comet 67P/Churyumov–Gerasimenko [1] [2] to test ideas regarding Solar System formation, and accretion of rocky planets with habitable surface environments.
NASA scientists say Jupiter-family comets like 67P could have helped deliver water to Earth
CAESAR (Comet Astrobiology Exploration Sample Return) is a sample-return mission concept to comet 67P/Churyumov–Gerasimenko.The mission was proposed in 2017 to NASA's New Frontiers program mission 4, and on 20 December 2017 it was one of two finalists selected for further concept development.
When the exploratory craft Philae landed on the surface of comet 67P/Churyumov-Gerasimenko, it sparked a sense of wonder and imagination among many. Astronomers Chandra Wickramasinghe and Max ...
10 December 2014 – Data from the ROSINA mass spectrometers show that the ratio of heavy water to normal water on comet 67P is more than three times that on Earth. The ratio is regarded as a distinctive signature, and the discovery means that Earth's water is unlikely to have originated from comets like 67P.
On 30 September 2016 mission ended in an attempt to slow land on the comet's surface near a 130 m (425 ft) wide pit called Deir el-Medina. Ariane 5G+ Philae: 2 March 2004: ESA / DLR Germany: 67P/Churyumov–Gerasimenko: Lander Successful: Carried by Rosetta. Came to rest on the surface of 67P at 17:32 UTC on 12 November 2014.
A recently discovered comet, named C/2023 A3 Tsuchinshan–ATLAS, makes its closest approach of Earth on Saturday. The comet’s next appearance may be in 80,000 years.
