Asteroid 2007 TU24

Discovered by the Catalina Sky Survey on October 11 last year, this 150-600m asteroid will closely approach the Earth in the next few days. It will pass within 1.4 lunar distances (roughly 335,000 miles) on January 29th at about 8a.m. GMT. It will almost reach magnitude 10 between the 29th and 30th and will then get fainter as it moves further from Earth. According to NASA’s press release, you might even be able to see it through a good telescope.

Here is a map, also from the NASA site, showing its path over the sky. You can also get a local ephemeris via this link.
