Its average distance from the Sun, not from Earth.
The radius of a ball that would look the same size — the body itself is not round.
How bright it would look from a fixed, standard distance — a measure of the object rather than of the view from here.
One trip round the Sun.
OBSERVING

CATALOG DATA

WHAT IT IS MADE OF
What the object is in itself, rather than how it happens to look from here.
- Spectral type (SMASS II)
- K
- Rotation period
- 4.79
HOW BRIGHT IT IS
What the light adds up to, measured through one filter at a time. A magnitude is a brightness on a backwards scale — the smaller the number, the brighter the object.
- Albedo
THE ORBIT
The shape of the path, where the object sits on it, and the instant those figures were true of. An orbit is a fit to observations and drifts away from the real one either side of its epoch.
