WASHINGTON (AP) — It’s a treat to see a supermoon. But that bright glowing orb will still be almost full when the Leonid meteor shower peaks this weekend, likely obscuring all but the brightest meteors in most locations. The Leonids are known for their high-speed meteors, which can travel at up to 44 miles per second (70 kilometers per second).

An annual meteor shower known for its fast movement and explosions of color that persist longer than average will peak this weekend, though experts say the shower’s peak won’t reach a maximum until just before the next century.

More a popular term than a scientific one, a supermoon occurs when a full lunar phase syncs up with an especially close swing around Earth. This usually happens only three or four times a year and consecutively, given the moon’s constantly shifting, oval-shaped orbit.
