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.

Galileo 's prime mission was a two-year study of the Jovian system, but on March 26, 1993, while it was en route, astronomers Carolyn S. Shoemaker, Eugene M. Shoemaker and David H. Levy discovered fragments of a comet orbiting Jupiter, the remains of a comet that had passed within Jupiter's Roche limit and had been torn apart by tidal forces.
Several sample-return missions to asteroids and comets are currently in the works with a key interest in astrobiology. More samples from asteroids, comets and moons could help determine whether life formed in other astronomical bodies, and if it could have been carried to Earth by meteorites or comets — a process termed panspermia.

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 discovered in the constellation of Equuleus by Father Nicolas Sarabat, a professor of mathematics, at Nîmes in the early morning of August 1, 1729. [7] At the time of discovery the comet was making its closest approach to Earth at a distance of 3.1 AU (460 million km; 290 million mi) and had a solar elongation of 155 degrees.
Asteroid research missions are complex endeavors and yield a tiny amount of material (less than 100 milligrams Hayabusa, [3] 5.4 grams Hayabusa2, [4] ~121.6 grams OSIRIS-REx [5]) relative to the size and expense of these projects ($300 million Hayabusa, $800 million Hayabusa2, $1.16 billion OSIRIS-REx).
Comet Tuttle rounds out the year with a minor meteor shower yielding about 5–10 meteors per hour. They’ll pop up from December 17–25, competing with a waning gibbous moon this year.
