'''2008 EA9''' is a very small near-Earth object about 17 meters in diameter, first detected  by NASAs Center for Near-Earth Object Studies (CNEOS), and is in an Earth-crossing orbit.
 
−
 
 
−
The [[Orbiter]] version was created by joffrey in 2012. It was modeled as a vessel rather than as a body.
 
−
 
 
−
It is a strange critter. It has size (10 meters diameter), it is visible, it has mass (1.2 million kg), which gives it a density of 764 kg/m, but it has no gravity. It does not rotate keeping the same orientation to the celestial sphere over time, therefore it has no poles nor equator. It cannot be selected as a reference body, but it can be selected as a target.
 
−
 
 
−
As a vessel, it can be targeted as stated before, has 6 invisible docks each with a COMNAV frequency assigned, but you cannot switch ships into it. In order for it to be the focus vessel, it must be stated as the focus vessel in the scenario file before launching the scenario. If you then switch from 2008 EA9 into another vessel, you cannot switch back, it does not appear in the switch ship list. Once you dock with it, you cannot change its orientation with engines or thrusters.
 
−
 
 
−
But, it is an interesting entity to rendezvous and dock with. The dock and land lights on the DeltaGlider work at 2008 EA9.
