, is an eccentric asteroid, classified as near-Earth object and potentially hazardous asteroid of the Apollo group. First observed by the Spacewatch survey on 8 October 2004, it may be a fragment of Comet Encke and is the source of the Northern Taurids meteor shower seen annually in November[1] and the June Beta Taurids.[2] The asteroid may be larger than one kilometer in diameter.
orbits the Sun at a distance of 0.3–4.2 AU once every 3 years and 4 months (1,220 days). Its orbit has an eccentricity of 0.86 and an inclination of 4° with respect to the ecliptic.
It has a Earth minimum orbital intersection distance of 0.0225abbr=onNaNabbr=on, which corresponds to 8.8 lunar distances.
According to the survey carried out by the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, the asteroid measures 1.316 kilometers in diameter and its surface has an exceptionally low albedo of 0.018, while Porubcan estimates a diameter of 350 to 780 meters, based on an albedo of 0.25 to 0.05, which typically covers most S-type and C-type asteroids.
