2002 RN109 is a
its ETS near Socorro, New Mexico, United States.[1] The unusual object is approximately 4 kilometers (2 miles) in diameter.[3] It has the second-highest orbital eccentricity of any known minor planet, after 2005 VX3.[5]
Description
2002 RN109 may be a
Lincoln Laboratory's Experimental Test Site on 16 August 2002, or three weeks prior to its first observation.[1] The observation arc is only 80 days long. The object has not been observed since November 2002, about 2 months before it came to perihelion 2.7 AU from the Sun.[2]
During perihelion passage the object was 2.9 AU from Earth.
2002 RN109 belongs to the dynamical group of
perihelion
.
