1998 KY26 was released by Nighthawke in the Asteroid Pack 1.00 in November 2004. It is modeled in Orbiter as a 30 meter diameter object orbiting the Sun from 1 to 1.5 AU once every 1.37 years, with an eccentricity of 0.201 and an inclination of 1.48°. Rotation is a bit over 10 minutes.

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 gravity of KY26 is so weak that OrbitMFD landed on the surface shows Sun 100% and KY26 0%. The pilot must be proactive to keep the ship on the surface.

1998 KY26 is a very small Near-Earth object disccovered by the Spacewatch survey at Kitt Peak on 2 June 1998.

1998 KY26 was released by Nighthawke in the Asteroid Pack 1.00 in November 2004. It is modeled in Orbiter as a 30 meter diameter object orbiting the Sun from 1 to 1.5 AU once every 1.37 years, with an eccentricity of 0.201 and an inclination of 1.48°. Rotation is a bit over 10 minutes.

The gravity of KY26 is so weak that OrbitMFD landed on the surface shows Sun 100% and KY26 0%. The pilot must be proactive to keep the ship on the surface.
