MYSTERY OBJECT: Yesterday, astronomers in Arizona, New Mexico and Spain, all hunting for near-Earth asteroids, discovered a "mystery object" orbiting Earth. Temporarily named "9U01FF6," it is small and in an elongated, 31-day orbit. Experts say it is probably a piece of an Apollo-era Moon mission. We'll get a closer look on Oct. 29th when it zips past Earth about 82,000 km (0.2 lunar distances) away. Advanced amateur astronomers can find it using this ephemeris [see link].
