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.
