An asteroid bigger than the world's most massive cruise ships will fly past the Earth today, and will be visible from Canada with strong binoculars or a small telescope – or you can watch it
streamed online starting at 11 a.m.
Based on its brightness, asteroid 2004 BL86 is estimated to be about 500 metres across. If it were sitting on the Earth, it would be as tall as Toronto's CN Tower.
At its closest approach at 11:19 ET, the huge space rock will be about 1.2 million kilometres (745,000 miles) from the Earth or about three times further away than the moon.
