Elements of orbits of all known centaurs
Data of discovery of all known centaurs
Note 1. If a centaur is marked by asterisk, it denotes an insufficient quantity of observations. New observations can to change the data of this table essentially.
Note 22. The Minor Planet Center (USA) proposed to assign the name "centaurs" to the objects with perihelion beyond the orbit of Jupiter (q>5.2AU) and with semimajor axis inside the orbit of Neptune (a<30.06AU). If to obey this rule, BU48, OX3, AS20, QB243 and PN34 desist to be centaurs, because their semimajor axes are bigger than one of Neptune.
Note 3. At first, astronomers estimate the period of the minor planet 1999 TD10 as 87 years. But then it developed that 1999 TD10 is not a centaur: this minor planet has a very elongate comet-like orbit and, hereby, belongs to SDO group (Scattered-Disk Objects). Similarly, asteroids 2001 XA255 and 2002 CR46 were taken at first for centaurs, which move near the orbit of Uranus, but following observations proved that XA255 in perihelion reaches the orbit of Saturn and in aphelion moves away in the Kuiper belt; and CR46 in the ultimate withdrawal goes even farther than cardinal cubewanos. So, XA255 and CR46 are relegated now to SDOs too.
