Surprise – Again! Asteroid Bennu
"The asteroid presented its first surprise in December 2018 when NASA’s spacecraft arrived at Bennu. The OSIRIS-REx team found a surface littered with boulders instead of the smooth, sandy beach they had expected based on observations from Earth- and space-based telescopes. Scientists also discovered that Bennu was spitting particles of rock into space."

The spacecraft is due to deliver its sample in September 2023.

Re: Surprise – Again! Asteroid Bennu
It seems that there should be two basic structures for asteroids that we encounter - those which are weakly-held accumulations of smaller bodies and those which are the product of fragmentation of larger astroidal bodies where much stronger gravitational forces might have previously melted/fused the progenitor's mass into truly solid form.
