Summary: Near-Earth asteroid 2001 YB5 raced past Earth on January 7, 2002, only two times farther away than the Moon. Just before the close encounter, the 300 meter-wide space rock brightened to 12th magnitude -- an easy target for backyard telescopes. [3D orbit] [ephemeris]

On January 3rd, days before the space rock's closest approach to Earth, T. Payer captured 5 images of 2001 YB5 spanning an 8-minute interval. He used a 12.5'' f/5.7 Newtonian reflector and a Starlight SXL8 CCD camera at the Walter-Hohmann Observatory. The visual magnitude of the asteroid was 15.8. [more]
