Interesting Facts about Asteroids

Asteroids and the Extinction of Dinosaurs

One of the most famous connections between asteroids and Earth’s history is the role they played in the extinction of the dinosaurs. Approximately 66 million years ago, a massive asteroid, around six miles in diameter, crashed into what is now the Yucatan Peninsula in Mexico.

The impact led to a global catastrophe, causing a chain reaction of events that led to the extinction of more than half of Earth’s species, including the dinosaurs.

Asteroid Moons

Did you know that some asteroids have their own moons? These moons, known as asteroid moons or moonlets, can range in size from a few meters to several kilometers.

They are often created when a large asteroid is struck by a smaller one, causing debris to form a “moon” around the larger object. One example is the asteroid 243 Ida, which was discovered to have its own moon, named Dactyl, when it was visited by the Galileo spacecraft in 1993.
