A near-Earth object is a dwarf planet.
A small number of NEAs are extinct comets that have lost their volatile surface materials, although having a faint or intermittent comet-like tail does not necessarily result in a classification as a near-Earth comet, making the boundaries somewhat fuzzy
As of January 12, 2023, and using diameters mostly estimated crudely from a measured absolute magnitude and an assumed albedo, 859 NEAs listed by CNEOS, including 152 PHAs, measure at least 1 km in diameter, and 10,362 known NEAs, including 2322 PHAs, are larger than 140 m in diameter
