Non-exhaustive list of artificial objects that have reached the surface of 162173 Ryugu, which is an Apollo-class asteroid orbiting the sun between Venus and Mars. This near-Earth object measures approximately 1 km in diameter and is potentially hazardous.
From June 2018 to November 2019, Ryugu was visited by the JAXA Hayabusa-2 deep space probe which retrieved surface samples and returned them to Earth in December 2020.
Estimated number of artificial objects: 15
Estimated total mass: 19.3 kg
