'''1998 KY26''' is a small rock that was seen passing [[Earth]] at about twice the lunar distance by [[w:Spacewatch|Spacewatch]] at the [[w:Kitt Peak National Observatory|Kitt Peak]] on 2 June 1998.

== 1998 KY26 in Orbiter ==
 
−
1998 KY26 was offered as an add-on body by [[List of add-ons by Nighthawke|Nighthawke]] in 2004, but still works even in Orbiter2016.

1998 KY26 is a small (about 15 meters) asteroid orbiting about 1 to 1.5 AU about every 1 year 4 months, and rotates in a bit more than 10 minutes. It is barely bigger than the DeltaGlider.
 
−
 
 
−
When landing on the radius surface, it is just a few meters above the visual surface, and the DeltaGlider docking and landing lights are reflected from the surface as one would expect. It has virtually no gravity, so, landing is just momentary, the ship immediately starts drifting as soon as it touches. A Ship cannot orbit the body because the [[Sun|Sun's]] gravity far exceeds the body's gravity, the pilot can only fly more or less in formation with it.
