2017 BQ6 is a sub-kilometer asteroid on an eccentric orbit, classified as a near-Earth object and potentially hazardous asteroid of the Apollo group, approximately 150 meters in diameter. It was discovered on 26 January 2017, by the Space Surveillance Telescope at Lincoln Laboratory's ETS (Atom Site) and passed within 6.6 lunar distances of Earth on 7 February 2017 at 6:36 UT.[1][2]

Radar imaging

Its closest approach was observed by NASA's Goldstone Solar System Radar in California's Mojave Desert, determining it to have a number of angular flat surfaces similar to a polyhedral die.

Orbit

2017 BQ6 orbits the Sun with a semi-major axis of 1.95 AU at a distance of 0.9–3.0 AU once every 2 years and 9 months (992 days). Its orbit has an eccentricity of 0.53 and an inclination of 9° with respect to the ecliptic. It has an Earth minimum orbital intersection distance of 0.0132 AU (1,970,000 km), which corresponds to 5.1 lunar distances.[1]

Physical characteristics

Based on an absolute magnitude of 21.4 and an assumed albedo for stony S-type asteroids of 0.20, 2017 BQ6 measures 156 meters in diameter.[4] The body has a rotation period of 2.15 hours and a brightness amplitude of 0.38 magnitude (U=2).[4]
