Seeing that image, with the boulders and rocks, makes me wonder - if you could progressively remove mass from Ryugu, how much smaller would it have to be that gravity wouldn't hold the boulders and rocks down and they'd just start floating?

Japan has successfully landed two small rovers on the surface of an asteroid in a history-making mission that could provide clues to the origin of the solar system.
Japan’s space agency (JAXA) released photos taken by the MINERVA-II-1 rovers from the surface of Ryugu, a kilometre-wide asteroid orbiting between Earth and Mars.
The rovers, each with a diameter of 18 centimetres, height of seven centimetres and weight of about 1.1 kilogram, were released from the Hayabusa2 spacecraft on Friday.

I am fascinated by these asteroids - as a child, I really loved the small planetoids of Little Prince, and these ones are the closes in real terms. It must be a unique experience to set foot on these. Jump, land in another half an hour... but probably I'd be too scared that I reach escape velocity by jumping. :)

BTW another triumph of navigation, again, in all the vastness of space track, find and actually brake (just think about how slow the orbit must be, yet how big the velocity difference was) to orbit this space mountain.
