If the weather cooperates tonight, you’ll be able to see the biggest supermoon since 1948. Supermoons occur when the moon is closer than usual to the earth. Tonight the moon will be a mere 356,511 kilometers (221,525 miles) away from us, so it will appear up to 14% larger and 30% brighter than usual. Get outside tonight to enjoy a little moonshine!
