'''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.

The landing surface (hard radius) is mostly below the visual surface, so most of the time landing on the hard surface will be below the visual. Landing inside will be sort of like being inside a cave looking at the backside of the skin of the body. If you're on the daylight side, you can see the sun kind of like looking at the sun through a thin cloud deck.

The landing light on the [[Delta-glider]] works on the visual surface of Ryugu, but not inside.
