How massive are asteroids?
See the relative sizes of twenty-two asteroids on this video from MetaBallStudio. Asteroids vary from human-scale 2008 TC3, which exploded in midair over the Sudan in 2008, to the large, spherical dwarf planet Ceres, largest object within the asteroid belt between Mars and Jupiter.

What number of identified near-Earth objects are there? 1000’s, principally very small. This chart reveals what number of have been found between 1980 and 2021.
