Big asteroid to fly by Earth Monday

The asteroid is called 2004 BL86. It’ll come about 745,000 miles (1.2 million kilometers) from Earth, or about three times as far away as the moon.

You’re wondering, doesn’t this happen all the time? Yes and no. There are lots of asteroids that pose a threat to Earth — about 550 as of today. None are predicted to hit anytime soon.
