(20026) 1992 EP11 is a yet to be named asteroid from the outer region of the asteroid belt, roughly 5 kilometers in diameter. It was discovered by the Uppsala-ESO Survey of Asteroids and Comets (UESAC) at ESO's La Silla Observatory in Chile, on 6 March 1992.[3]
The asteroid orbits the Sun at a distance of 2.7–3.0 AU once every 4 years and 10 months (1,760 days). Its orbit shows an eccentricity of 0.04 and is tilted by 3 degrees to the plane of the ecliptic. Little is known about the asteroids size, composition, albedo and rotation, despite having a well-observed orbit with the lowest possible uncertainty – a condition code of 0 – and an observation arc that spans over a period of more than two decades.[1] Based on its absolute magnitude of 14.5, its diameter could be anywhere between 3 and 7 kilometers, assuming an albedo in the range of 0.05 to 0.25.[2]
