National Moon Day – July 20, 2019

Sat Jul 20

Why is the moon important? Could it be the tides? Could it be that it lights up our skies at night so that we can see? The fact that it helps us keep our calendars in check? Could it be that it is just beautiful and loved and worshiped around the world? Or maybe because of all these reasons? Join us on July 20th, as we celebrate National Moon Day!

National Moon Day Activities

  1. Visit your local planetarium

    Look online for your local planetarium! Planetariums are domed theaters that project images of the starry sky and countless spectacular objects we find in our universe, creating educational experiences that teach astronomy and related sciences. So if you're looking for an IMAX immersive experience to learn more about the moon at, your local planetarium is the way to go!

  2. Hang out with your local Astronomy club

    Use this handy link to find your local astronomy club. Chances are they will be very excited to tell you about all the upcoming events, show you things in their telescopes or just chat to you with their extensive knowledge of the skies!

  3. Find out when the next lunar eclipse is

    Get ready for a nighttime show! Schedule in your calendar when the next lunar eclipse will be and make plans to bring a blanket, some picnic foods, binoculars or a telescope and head outside to see it for yourself! you'll be happy you made time to get outside and enjoy one of natures most interesting and accessible shows!

Why We Love National Moon Day

  1. The Big Whack

    The moon formed 'the Big Whack'! A giant Mars-sized object hit Earth 4.6 billion years ago and a cloud of vaporized rock went into orbit around Earth. The cloud cooled and formed into smaller chunks that combined to form our moon.

  2. It's size

    The moon is about 27 percent the size of Earth, and has much less gravity; If you weigh 150 pounds on Earth, you'd weigh 25 pounds on the moon.

  3. Moonquakes

    The moon has earthquakes that sometimes form cracks, where gasses escape! What a strange landscape for the Apollo crew to walk on don't you think?
