Today's Topic

On 8 November, a 400-meter-wide asteroid dubbed 2005 YU55 will zip past Earth within just a few hundred thousand kilometers. This flyby will give astronomers and the public alike a rare look at what scientists call near-Earth objects. At the same time, satellite data, including information from NASA's Wide-Field Infrared Survey Explorer, has illustrated the diversity of such rocks in orbit dangerously close to our planet. What do scientists expect to learn in the wake of 2005 YU55's flyby? What do astronomers know about the abundance and behavior of near-Earth objects? And what dangers do these space rocks present to human civilization?

Join us for a live chat about near-Earth objects at 3 p.m. EDT on Thursday, 3 November, on this page. You can leave your questions in the comment box below before the chat starts.
