Editing Kuiper belt (section)

=== Satellites ===
The six largest TNOs ([[Eris (dwarf planet)|Eris]], [[Pluto]], [[225088 Gonggong|Gonggong]], [[Makemake]], [[Haumea]] and [[50000 Quaoar|Quaoar]]) are all known to have satellites, and two of them have more than one. A higher percentage of the larger KBOs have satellites than the smaller objects in the Kuiper belt, suggesting that a different formation mechanism was responsible.<ref>{{cite journal |doi=10.1086/501524 |last1=Brown |first1=M.

The most notable example is the Pluto–Charon binary, but it is estimated that around 11% of KBOs exist in binaries.<ref>{{cite journal |first1=C.B. |last1=Agnor |first2=D.P. |last2=Hamilton |title=Neptune's capture of its moon Triton in a binary-planet gravitational encounter |journal=Nature |volume=441 |date=2006 |pages=192–4 |url=http://www.astro.umd.edu/~hamilton/research/reprints/AgHam06.pdf |doi=10.1038/nature04792 |pmid=16688170 |issue=7090 |bibcode=2006Natur.441..192A |s2cid=4420518 |access-date=9 July 2010 |archive-date=3 November 2013 |archive-url=https://web.archive.org/web/20131103235809/http://www.astro.umd.edu/~hamilton/research/reprints/AgHam06.pdf |url-status=live }}</ref>
