162173 Ryugu is a near-Earth object and a potentially dangerous asteroid of the Apollo group. It is about 1 kilometer (0.6 mi) in diameter and is a dark object.[1]

In June 2018, the Japanese spacecraft, Hayabusa2, arrived at the asteroid.[2] After making measurements and taking samples, Hayabusa2 left Ryugu for Earth in November 2019[3] and returned to Earth on 5 December 2020.
