A gigantic asteroid nearly 900 feet wide will race past planet Earth tonight, a harmless but sobering reminder of the dangers posed by such interplanetary visitors. On Monday, Feb. 17, at approximately 9:00p.m. EST (7 p.m. Tucson time), the Slooh space telescope will broadcast a live video stream and scientific discussion about the silent visitor, which will be traveling at approximately 27,000 miles per hour when it soars safely past the planet. The asteroid, called NEA 2000 EM26, will come no closer than 8.8 lunar distances from Earth -- a measure of the distance between us and the moon -- and poses no threat to us.
