A huge asteroid flew past the Earth today, and is expected to be visible from Canada with strong binoculars or a small telescope tonight. Based on its brightness, asteroid 2004 BL86 was estimated to be about 500 metres across. But NASA scientists later revised their estimate to about 300 metres, based on radar measurements. If it were sitting on Earth beside Torontos CN tower, its top would be a little lower than the revolving restaurant.
