A black supermoon is coming this week

The moon is going to be at its closest on Wednesday, February 18, but since it's a new moon, so you won't see a thing.

This is called a black supermoon, and it happens around three times a year. While there's nothing to look at, some superstitious people consider it significant.

Here's a look at how lunar position will block our view:When the moon is at its closet - called perigee - during a full moon or new moon, that's called a supermoon.

The last three will happen during a full moon and take place in August, September, and October. On September 28, the supermoon will occur around the same time as a total lunar eclipse, where the east coast will have prime seating for the event.
