|Small objects – panel 1/2||Major News for 31 Oct. 2004|
A week with a full Moon is tough on observing minor objects, but it's a good time to do archive work. Josep Julia Gomez found six small asteroids (defined at right) in the SkyMorph archive, including a 2001 prediscovery and additional positions for other objects from that year and one in 2002.
A total of four near-Earth asteroid discoveries were announced this past week, all on Tuesday, including a small one, 2004 UT1 discovered by LINEAR in New Mexico. And it made the week's only known close Earth flyby, passing at two lunar distances on Thursday. Nothing so close is predicted for the coming week.
Four other small asteroids were reported observed, and ten observing facilities participated in the week's work.
Whats so big about small objects? If an asteroids orbit brings it to within 0.05 astronomical units (AU) of Earth's orbit, it is categorized as potentially hazardous unless it has an absolute magnitude H greater than 22.0, which corresponds to a diameter on the order of 135
