Explanation Of Symbols

Designation (and name) -   For numbered minor planets, this column contains the object's number and name.

Prov. Des. - The object's provisional designation. Note that some have old-style provisional designations (letters recycled without regard to the calendar).

q -        Perihelion distance (in AU).

Q -       Aphelion distance (in AU).

H  -      Absolute visual magnitude. (A table converting H to a diameters is available on the website above)

a  -       Semimajor axis (in AU). (OR Mean Solar Distance [MSD])

Opps -  Number of oppositions (with the Sun) observed. (This will usually be the number of years since discovery date)

Ref. -    Reference to the published orbit, generally to the MPCs (= Minor Planet Circulars)

***        Sedna is included here, although it is classified as a ‘Scattered Disk Object’, not a Centaur.
