Critical-list minor planet

Source: Wikipedia, the free encyclopedia.

A critical-list minor planet (critical list numbered object or critical object) is a numbered minor planet for which existing measurements of the orbit and position are especially in need of improvement.[1]

The

astrometric community.[5]

arcseconds over the next 10 years, and objects whose orbits degrade significantly when temporally isolated observations are ignored, are included in the list.[3]

List

As of August 2023[update], the MPC includes 1,494 objects in their critical list. This list contains all critical objects within the first 50,000 numbered minor planets:[6]
