Ryugu is a near-Earth object, asteroid of the Apollo group discovered 10 May 1999. Ryugu is approximately 1 km in diameter, of spectral type Cb. The asteroid orbits the Sun every 16 monmths.

It was visited in June 2018 by the Japanese spacecraft JAXA Hayabusa2 which returned a sample capsule to earth on 5th December 2020 containing samples from the asteroid.

The mission also involved deploying two rovers, MINERVA-II-1A and MINERVA-II-1B and a lander - Mobile Asteroid surface SCOuT (MASCOT).
