    #29981 (1999 TD10) was at first called a Centaur, but additional findings move it out of that class and into the same class as 1996 TL66 (see below)and other Scattered Kuiper-belt objects. The new elements can be seen at: #29981 (1999 TD10)

    And here are the orbital elements for:

    The first body discovered past Pluto: #15760 (1992 QB1)
    The first Icy Mini Planet (Transpluto?): #15874 (1996 TL66)
    And, of course, the second Icy Mini Planet: #19308 (1996 TO66)
    And one TNO, numbered 28978, was named after the father of the Centaurs, (28978) IXION

    And of course, we must not forget Eris, (136199) Eris

    Here is a table showing the orbital elements of TNOs, SDOs, and Centaurs:

    ORBITAL ELEMENTS

    Drawings of the Centaurean orbits, showing how each relates to the other bodies of our solar system, and including the distance from the Centaurean body to the Earth, and the Sun. Orbital drawings show the bodies for January 2006. (All images calculated by this N.A.S.A. Minor Planet Orbit Plotter):

    And here are orbital drawings of a few other bodies, again showing the bodies in January 2006:

    Heracles

    Orcus (90482)
    Quaoar (5000)
    Rhadamanthus (38083)
    Sedna (90377), partial orbit
    Sedna (90377), whole orbit
    Varuna (2000)
    Eris (136199), partial orbit
    Eris (136199), whole orbit

    The Centaurs are orbit crossers. For an excellent chart showing when each Centaur crosses the orbit of a major planet, go to Orbit Crossings

    To discover when each Centaur has been closest to the Sun (perihelion) and furthest away (aphelion), check out Perihelia & Aphelia

    The station dates (2000-20200 of a few Centaurs, Asbolus, Chariklo, Elatus, Okyrhoe, Pholus and Nessus, can be found at Stations

    For the more technically minded, these sites have hundreds of links to scientific papers about the various Centaurs:

    The Centaurs are part of a whole slew of distant minor planets, which include cubewano's (like 15760) and plutino's (like 1993 RO). You can find the most updated list of all of these bodies at this MPC site

    And here is an interesting article about the bodies past Neptune/Pluto: Trans-Neptunian's

    Mike Brown, one of the discovers of Eris, Sedna, Orcus and Quaoar has a webpage well worth exploring: Mike Brown's page

    Chad Trujillo, co-discoverer with Mike Brown and David L. Rabinowitz of many bodies out past Pluto, also has a webpage: Chad Trujillo's page
