162173 Ryugu or in Orbiter simply Ryugu is near-Earth object of the Appolo group of small bodies, discovered by Lincoln Near-Earth Asteroid Research astronomers on 10 May 1999.

Ryugu is an add-on by francisdrake released in 2023 on the forum, and is compatible with Orbiter 2016. In Orbiter, Ryugu orbits the Sun with a semi-major axis of 1.19 AU, inclination of 0.1027 radians, and eccentricity of 0.19. Its gravity is very weak, even at the surface, in OrbitMFD, Ryugu's gravity is 1% and the Sun's gravity is 99%. A person could literally jump at greater than escape speed. Rotation is just over a day.
