(374158) 2004 UL is a sub-kilometer
perihelion of any known asteroid, after (137924) 2000 BD19.[citation needed
]
It was discovered on 18 October 2004 by the
Lincoln Lab's ETS near Socorro, New Mexico.[2]
Orbit and classification
This Apollo asteroid orbits the Sun at a distance of 0.09–2.44
semi-major axis of 1.27 AU). Its orbit has an outstandingly high eccentricity of 0.93 and an inclination of 24° with respect to the ecliptic.[1]
Due to its orbit, it is also a
lunar distances.[1]
Physical characteristics
2004 UL is an assumed stony S-type asteroid.[4]
In October 2014, a rotational
U=2).[5]
Based on a generic magnitude-to-diameter conversion, 2004 UL measures between 0.5 and 1.2 kilometers.[3] The Collaborative Asteroid Lightcurve Link assumes a standard albedo for stony asteroids of 0.20 and calculates a diameter of 0.516 kilometers with an absolute magnitude of 18.8.[4]
