List of comets

[edit]

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 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.

Notes

[edit]
  1. ^ The vast majority of this mass comes from 2 Pallas, with only 1E17 kg (0.04% of the mass) from every other member of the family
  2. ^ 3 Juno makes up such a massive proportion of this family's mass that the mass is virtually the same with only Juno included, the other asteroids making up less than 0.02% of the total group mass

Notes

[edit]
  1. ^ Gaia DR2 has a distance measurement of Abell 2's central white dwarf, but the measured parallax is an impossible -0.67 ± 0.57 mas, only ruling out the star being closer than 10,000 light-years away.
  2. ^ upper limit for distance based on H-R diagram dynamics
  3. ^ The central star has a measured parallax in Gaia DR2 of -0.33 +/- 0.34 mas, which conflicts highly with other distance estimations.
  4. ^ based on the luminosity of the central white dwarf
  5. ^ a b c d e f g h i j k l m n o p q r s t u based on luminosity of the central star
  6. ^ Gaia parallax is almost certainly in error, value is based on assumptions about companion star luminosity
  7. ^ Gaia measures a parallax of the central star as an impossible -1.24 ± 0.37 mas.

Data values are sourced from the individual articles, where available, for each nebula. Please see the article of the nebula in question for data references.

Many distances are estimates (denoted by the approx. suffix), as true distances are difficult to infer for planetary nebulae. Please see main article, Planetary nebulae, for more details on distance estimates.

List of comet groups

[edit]

The following is a list of known families of comets in the Solar System. Comets are exceptionally prone to breaking apart among Solar System objects, due to the forces involved in their slow disintegration as the ices and volatiles they are marde up of slowly evaporate.

List of temporary moons of Jupiter

[edit]

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)

Temporary cometary moons

[edit]
See also: quasi-Hilda comet

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:
