(416151) 2002 RQ25
is a carbonaceous asteroid of the Apollo group, classified as near-Earth object and potentially hazardous asteroid, approximately 0.2 kilometers in diameter. It was discovered on 3 September 2002, by the Campo Imperatore Near-Earth Object Survey at the Italian Campo Imperatore Observatory, located in the Abruzzo region, east of Rome.
Orbit and classification
orbits the Sun at a distance of 0.8–1.5 AU once every 1 years and 2 months. Its orbit has an eccentricity of 0.31 and an inclination of 5° with respect to the ecliptic.The asteroid's minimum orbit intersection distance with Earth is, which is currently exactly at the threshold limit of 0.05 AU to make it a potentially hazardous object.
Physical characteristics
The carbonaceous C-type asteroid is also classified as a C/X-type body according to the survey carried out by NASA's Spitzer Space Telescope.Lightcurve
A rotational lightcurve of was obtained from photometric observations made by American astronomer Brian Warner at his Palmer Divide Observatory, Colorado, in February 2015. The ambiguous lightcurve rendered a rotation period of hours with a brightness variation of 0.72 magnitude, while a second solution gave 6.096 hours with an amplitude of 0.43.The Collaborative Asteroid Lightcurve Link assumes a standard albedo for stony asteroids of 0.20 and calculates diameter of 225 meters with an absolute magnitude of 20.6.
