CAPE CANAVERAL, Fla. (AP) — An asteroid more than 1½ miles long will zoom past Earth this week from a far-off distance.

The big rock called Asteroid 1998 QE2 will make its closest approach Friday. It will keep a safe distance of 3.6 million miles, or 15 times the distance between Earth and the moon. You won’t be able to see it without a powerful telescope.
