How big are asteroids?
See the relative sizes of 22 asteroids in this video from MetaBallStudios. Asteroids range from human-scale 2008 TC3, which exploded in the air over the Sudan in 2008, to the enormous, spherical dwarf planet Ceres, largest object in the asteroid belt between Mars and Jupiter.
Want to learn more about asteroids? In 2021, ESO released the video below about the 42 largest objects in the main asteroid belt. ESO’s Very Large Telescope in Chile has imaged these 42 of the asteroids, showing the variety that exists in the region between Mars and Jupiter.
Asteroids near Earth
Earth-crossing asteroids are space objects whose orbits cross that of Earth. Of course, Earth is most likely far away in its orbit from the spot where they cross. Here is a list of Earth-crossing minor planets.
Occasionally, Earth and an asteroid meet where their orbits connect. Fortunately, most of these asteroids are so small that they don’t make much of an impact.
How many known near-Earth objects are there? Thousands, but mostly very small. This chart shows how many scientists have been discovered between 1980 and 2023.
Bottom line: See how big 22 asteroids are in comparison to New York City.
