NASA helpfully offers us this short clip to explain the rarity of this coming Sunday’s lunar eclipse, which also coincides with a supermoon, the point on the moon’s elliptical orbit when it is closest to us on Earth, making it appear up to 14% larger. As explained in the clip, this particular alignment of events has only occurred five times since 1900, the last supermoon eclipse having been in 1982. And if you miss out on this Sunday’s moon, you’ll have to wait until 2033 to witness the phenomenon again. Mark your calendars, moon lovers!
