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.

Orbital period: 68.17
Eccentricity
Inclination: 44.62
Longitude of ascending node: 85.87
Argument of perihelion: 64.51
Mean anomaly: 341.22
Element epoch: 2459193.5000
Perihelion passage: 2460492.2300
Minimum distance from Earth's orbit: 0.47
Orbit class: HTC

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.
