oh don't mind me, just working on some stuff on minor planets & exoplanets (an artist's rendition of a box)

=List of comets=

Good news, ~20-40 people who were seeing my list under construction! I finally finished it! At more than half a million bytes, it's the fourth (almost third) longest article in all of Wikipedia! There's still plenty to do, though. Any help you can do now is appreciated!

=A106fgF=

A106fgF was an unconfirmed object discovered on 22 January 2018 by the Asteroid Terrestrial-impact Last Alert System (ATLAS). It was discovered in 4 images spanning less than 40 minutes, but was only recognized 6 hours later, by which point it was too late to follow up.

Orbital calculations by several sources including the ATLAS team, JPL Horizons, the Minor Planet Center, and Projectpluto, showed that the object had a 9% chance of impacting Earth at ~19:00 UTC on the same day. With a nominal size of 1-4 meters, it should have been detectable to various fireball-detecting satellites as a fireball with an energy of 0.02-2.6 kilotons. If it did hit, it would have impacted over a region between the south Atlantic Ocean, southern Africa, the Indian Ocean, Indonesia, or in the western Pacific ocean near Chuuk. An impact further west (in the Atlantic) would have meant the asteroid was discovered further away, and therefore larger, and further east (in the Pacific) would have meant that the asteroid was discovered nearer, and therefore smaller.

=List of temporary moons of Jupiter= The following comets between 1800 and 2200 will become, or have been briefly gravitationally bound to Jupiter as temporary satellites:

D/1977 C1 (Skiff-Kozai) may have been orbiting Jupiter during 1973 and earlier, but with only 8 recorded observations over 27 days, its orbit is too poor to know for certain. P/1999 XN120 39P 74P (2081-2085)

158P/Kowal-LINEAR entered orbit of Saturn some time in 1935 or 1936.

Temporary cometary moons
Due to its large gravity and the large population of short-period comets, a number of quasi-Hilda comets will occasionally become temporarily trapped in Jupiter's gravity. The most famous example, Comet Shoemaker-Levy 9 orbited Jupiter for at least two decades before eventually breaking up and impacting the planet in July 1994. However, the majority of comets captured by Jupiter are eventually ejected, often before finishing a complete orbit.

The following known comets have been, are, or will be captured by Jupiter's gravity between 1800 and 2200:
