Entered orbit around 67P at 09:06 UTC on 6 August 2014. 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.
(a) Due to a non-spherical, irregular shape, a comet's x, y, and z axes instead of an (average) diameter are often used to describe its dimensions. (b) Closest approach given in multiples of the comet's (average mean) radius · List ordered in ascending order by a comet's first visit.
COmet Rendezvous, Sample Acquisition, Investigation, and Return (CORSAIR) is a concept mission to return comet nucleus samples to Earth for detailed analysis.The mission concept was submitted in May 2017 by a team from NASA's Goddard Space Flight Center in response to the New Frontiers program call for mission 4, but did not pass the initial down selection.

The second moon that Earth has captured in its orbit this month is an asteroid called 2024 PT5. Mini-moons like this could be ideal targets for asteroid mining to send humans deeper into space ...
The comet was observed by iSHELL spectrograph at the NASA Infrared Telescope Facility (IRTF). Overall, the measured spatial distributions for polar molecules (in particular, H 2 O and CH 3 OH ) were broader, exhibiting more complex structure compared with nonpolar or weakly polar species ( CH 4 , C 2 H 6 , and CO ).
Astronomers posed over the past decade that dark comets, or objects that resemble asteroids but move like comets, may exist. Now, scientists have found a total of 14 of them.
