2017 CJ56 is a . Its absolute magnitude () is 9.05. It orbits the Sun at a mean distance of 49 .

WHAT IT IS
Trans-Neptunian object
HOW FAR
49

Its average distance from the Sun, not from Earth.

HOW BRIGHT IN ITSELF (H)

How bright it would look from a fixed, standard distance — a measure of the object rather than of the view from here.

ONE ORBIT TAKES
342

One trip round the Sun.

CATALOG DATA

] 11 FIELDS

The raw catalogue values, as the source published them, with the error bars where one was published — sorted by what each set of figures is about rather than by the order they happened to be stored in.

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.

LOOK IT UP ELSEWHERE

] 1 SERVICE

Each link carries the identifier printed beside it. Nothing on this page is a measurement of our own, so a number that disagrees with one of these is worth reporting — and a service that has never catalogued this object under this name will say so plainly.

This page is live and its numbers move when an upstream refreshes, so the citation names the release the rows belong to rather than the day you read them. The release itself is frozen, republished as a bundle, and is what a data-availability statement should point at.
