=== Trojans ===
{{Main|Trojan (celestial body)}}
Trojans are populations that share an orbit with a larger planet or moon, but do not collide with it because they orbit in one of the two [[Lagrangian point]]s of stability, {{L4|nolink=yes}} and {{L5|nolink=yes}}, which lie 60° ahead of and behind the larger body.

In the Solar System, most known trojans share the [[Jupiter trojan|orbit of Jupiter]]. They are divided into the [[Greek camp]] at {{L4|nolink=yes}} (ahead of Jupiter) and the [[Trojan camp]] at {{L5|nolink=yes}} (trailing Jupiter). More than a million Jupiter trojans larger than one kilometer are thought to exist,<ref name=Yoshida2006>{{cite journal

In other planetary orbits only nine [[Mars trojan]]s, 28 [[Neptune trojan]]s, two [[Uranus trojan]]s, and two [[Earth trojan]]s, have been found to date. A temporary [[2013 ND15|Venus trojan]] is also known. Numerical orbital dynamics stability simulations indicate that Saturn and Uranus probably do not have any primordial trojans.<ref name="sheppard2006">{{cite journal |last1=Sheppard |first1=Scott S. |last2=Trujillo |first2=Chadwick A. |date=June 2006 |title=A Thick Cloud of Neptune Trojans and their Colors |url=http://www.dtm.ciw.edu/users/sheppard/pub/Sheppard06NepTroj.pdf |url-status=dead |journal=Science |volume=313 |issue=5786 |pages=511–514 |bibcode=2006Sci...313..511S |doi=10.1126/science.1127173 |pmid=16778021 |s2cid=35721399 |archive-url=https://web.archive.org/web/20120220141846/http://www.dtm.ciw.edu/users/sheppard/pub/Sheppard06NepTroj.pdf |archive-date=20 February 2012 |access-date=15 April 2022 }}</ref>
