Known as the Chicxulub impactor, this large object has an estimated width of 6 miles (9.6 kilometers) and produced a crater in Mexico’s Yucatan peninsula that spans 90 miles (145 kilometers).
Can we live on an asteroid?
In space, cosmic rays and solar flares create a lethal radiation environment. … One possibility for defense against this radiation is living inside of an asteroid. It is estimated that humans would be sufficiently protected from radiation by burrowing 100 meters deep inside of an asteroid.

What is the largest asteroid near Earth?
What are the 3 largest asteroids?
Ceres, Pallas, and Vesta are the three largest asteroids. Even though they are much smaller than the planets (Ceres, the largest asteroid, has only 1% the mass of the Moon), they are still capable of causing changes in the orbits of Mars and the Earth.
What do asteroids do?
Asteroids are rich sources of metals like Iron, Platinum and Titanium, metals that humans use daily to build and create things. In addition, scientists believe that water present on the surface of these asteroids could be broken down and used as fuel for space vehicles.
