Asteroids in fiction
After Ceres, Asteroid 433 Eros is perhaps the most-commonly mentioned asteroid, probably because it is one of the largest near-Earth asteroids.

The larger in size asteroids or other near-Earth objects (NEOs) are, the less frequently they impact the planet's atmosphere — large meteors seen in the skies are extremely rare, while medium-sized ones are less so, and much smaller ones are more commonplace. Although stony asteroids often explode high in the atmosphere, some objects, especially iron-nickel meteors and other types descending at a steep angle, can explode close to ground level or even directly impact onto land or sea. In the U.S. State of Arizona, the -wide Meteor Crater (officially named Barringer Crater) formed in a fraction of a second as nearly 160 million tonnes of limestone and bedrock were uplifted, creating its crater rim on formerly flat terrain. The asteroid that produced the Barringer Crater was only about 46 meters (150 ft.) in size; however it impacted the ground at a velocity of 12.8 kilometers per second (28,600 mph) and struck with an impact energy equivalent to a 10 megaton (TNT equivalent) nuclear bomb — about 625 times greater than the bomb that destroyed the city of Hiroshima during the Second World War. Tsunamis can also occur after a medium-sized or larger asteroid impacts an ocean surface or other large body of water.
