Editing Jupiter trojan (section)

== Nomenclature ==
The custom of naming all asteroids in Jupiter's {{L4|nolink=yes}} and {{L5|nolink=yes}} points after famous heroes of the [[Trojan War]] was suggested by [[Johann Palisa]] of [[Vienna]], who was the first to accurately calculate their orbits.<ref name=Nicholson1961/>

Asteroids in the leading ({{L4|nolink=yes}}) orbit are named after [[Ancient Greece|Greek]] heroes (the "Greek node or camp" or "[[Achilles]] group"), and those at the trailing ({{L5|nolink=yes}}) orbit are named after the heroes of [[Troy]] (the "Trojan node or camp").<ref name=Nicholson1961/> The asteroids [[617 Patroclus]] and [[624 Hektor]] were named before the Greece/Troy rule was devised, resulting in a "Greek spy", [[Patroclus]], in the Trojan node and a "Trojan spy", [[Hector]], in the Greek node.<ref name=Wyse1938/><ref name="spies">{{cite web|title=Trojan Asteroids|url=http://astronomy.swin.edu.au/cosmos/T/Trojan+Asteroids|website=Cosmos|publisher=Swinburne University of Technology|access-date=13 June 2017|archive-url=https://web.archive.org/web/20170623182748/http://astronomy.swin.edu.au/cosmos/T/Trojan+Asteroids|archive-date=23 June 2017|url-status=live}}</ref>

In 2018, at its 30th General Assembly in Vienna, the [[International Astronomical Union]] amended the naming convention for Jupiter trojans, allowing for asteroids with ''[[Absolute magnitude#Solar System bodies (H)|H]]'' larger than 12 (that is, a [[mean diameter]] smaller than approximately 22 kilometers, for an assumed albedo of 0.057) to be named after Olympic athletes, because there are now far more known Jupiter trojans than available names of [[List of Trojan War characters|Greek and Trojan warriors]] that fought in the Trojan war.<ref>{{Cite web |title=MPEC 2020-T164 |url=https://minorplanetcenter.net/mpec/K20/K20TG4.html |access-date=2024-07-20 |website=minorplanetcenter.net}}</ref>
