A Neptune-crosser is a minor planet whose orbit crosses that of Neptune. The dwarf planet Pluto is the most massive example of this class of object. The known numbered Neptune-crossers (as of 2005) are: Notes: ‡ outer-grazer † 134340 Pluto was known at this time but not numbered 5145 Pholus 7066 Nessus 10370 Hylonome (15788) 1993 SB (15820) 1994 TB (15875) 1996 TP66 (19299) 1996 SZ4 (20161) 1996 TR66 20461 Dioretsa (26308) 1998 SM165 ‡ 28978 Ixion ‡ (29981) 1999 TD10 (32929) 1995 QY9 (33128) 1998 BU48 (33340) 1998 VG44 38628 Huya 42355 Typhon (44594) 1999 OX3 (47932) 2000 GN171 52975 Cyllarus (54520) 2000 PJ30 55576 Amycus (55638) 2002 VE95 (60608) 2000 EE173 (65407) 2002 RP120 65489 Ceto (73480) 2002 PN34 (78799) 2002 XW93 (84719) 2002 VR128 (87269) 2000 OO67 (87555) 2000 QB243 (88269) 2001 KF77 (134340) Pluto † See also List of centaurs (small Solar System bodies) List of Mercury-crossing minor planets List of Venus-crossing minor planets List of Earth-crossing minor planets List of Mars-crossing minor planets List of Jupiter-crossing minor planets List of Saturn-crossing minor planets List of Uranus-crossing minor planets Neptune Neptune-crossing Neptune-crossing Minor planets
