Smaller asteroids are far more common and present a greater theoretical concern in the near term, making the Didymos pair suitable test subjects for their size, according to NASA scientists and ...

Six other asteroids, which are basically leftover rocks that are over four billion years old, are also passing by Earth this week. However, they are all smaller than 2021 KT1.
