Names are the people who usually observe at that site, from Project Pluto's tables. MPC's astrometry records only the observatory code, never the individual, so these are not the observer of this particular object. Automated surveys list a telescope and no people.

Variant orbits	2000
Distinct positions	167 MPC rounds offsets to whole arcseconds — this cloud is small enough that the rounding dominates

Drawn from MPC's own variant-orbit offsets, at the same epoch as their plot. Each orbit is one solution consistent with the observations so far; the ring marks the nominal position, and the field box appears only when it is comparable in size to the cloud.

Dot size shows how many variants share a position. MPC publishes these offsets rounded to whole arcseconds, so a tightly constrained object has thousands of orbits landing on a handful of grid points — their own picture is drawn from unrounded values and looks smoother. Sizing by count puts that density back rather than stacking invisible dots. Hover any dot for its share.
