Video: Cool movie of close-passing asteroid 2004 BL86

Radar data obtained from NASA’s Deep Space Network antenna at Goldstone, California and the Green Bank Telescope in West Virginia were used to make this movie of asteroid 2004 BL86 and its small, newly discovered moon.

The asteroid and its moon passed closer to Earth last Monday (January 26, 2015) than any asteroid this large will again until the year 2027. At its closest, the pair was about three times the moon’s distance.
