Hi,
NASA have a small probe that just made a touch & go landing on an asteroid to pick up a few ounces of material.
Bennu is about 490m across and a little denser than water.
It weighs about 70 million tonnes making its surface gravity 7 exp-6 g.
The probe had been orbiting Bennu at a height of 870m taking about 48 hours at speed of 30mm per second.
The range from Earth is about 200 million miles or 18 minutes at light speed.
Nice bit of remote control....
