Our Moon is always the same big white ball going around Earth, but it doesn’t look the same every day. Sometimes it’s a C-shape, while other times it’s a fat white circle. Also, the Moon isn’t always equally far from us. Today’s full moon is exciting because it happens almost exactly when the Moon is closest to us. So the Moon looks about 1/7 bigger and 1/3 brighter than the farthest full moon. It’s the biggest supermoon since 1948! How bright is a full moon, anyway? It’s around 1 “lux,”while the light in your house is about 50 lux, and the Sun is 400 lux. Check out the Moon tonight, too — it won’t look as big again until the year 2034!

Wee ones: Hold up your two hands and cup them to make a circle, like tonight’s full moon!

Little kids: The Moon was exactly full at about 9:00 this morning New York time, but was closest to Earth about 3 hours earlier. At what time was the Moon closest to us?  Bonus:We’ve had 1 full moon each calendar month this year. How many have we now had in 2016?

Big kids: This month’s full moon is the Beaver Moon. The Flower Moon was 6 months ago. In which month did we have the Flower Moon?  Bonus: How old will you be for the next equally super Supermoon in 2034?




Wee ones: Make a circle with your hands.

Little kids: At 6:00 am.  Bonus: 11 full moons.

Big kids: In May.  Bonus: Different for everyone…2034 is 18 years from now, so add 18 to your current age.
