How big are asteroids? See comparative sizes in this video

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.

The primary 10 objects proven within the video are near-Earth objects, some designated as potentially hazardous. The remaining reside distant from Earth, principally within the asteroid belt.

On October 12, 2021, ESO launched a brand new video concerning the 42 largest objects in the principle asteroid belt.

Earth-crossing asteroids are area objects whose orbits cross that of Earth. In fact, Earth is probably distant in its orbit from the spot the place they cross. Here’s a list of Earth-crossing minor planets.

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.
