Template:Mp, 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,[1] it may be a fragment of Comet Encke and is the source of the Northern Taurids meteor shower seen annually in November[2][3] and the June Beta Taurids.[4] The asteroid may be larger than one kilometer in diameter.

Orbit

Template:Mp 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.[5]

It has an Earth minimum orbital intersection distance of Script error: No such module "convert"., which corresponds to 8.8 lunar distances.[5]

Physical characteristics

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,[6] 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.[2]
