The large space rock will be about half as close as the moon when it zooms past us at around 5:05 PM Central time.
The naked eye won't catch it, but a telescope could, or you could just watch the feed on Facebook from a London observatory.
It will be traveling 28,655 mph and will come within 126,419 miles of Earth.
What are you doing at 5:05 tomorrow night:
(A) Watching it,
(B) Sleeping, or
(C) Eating dinner?
