The asteroid’s big secret, revealed.
When scientists first observed the asteroid Bennu up close in 2018, they were shocked to find that its surface was covered with sizeable boulders.
And they’re comparatively smaller than other asteroids out there.
For example, Bennu has a diameter of 0.3 miles, while the much smoother asteroid Eros (below) has a diameter of almost 10.5 miles.
Now, scientists will put the models to the test.
