Celebrate Observe the Moon Night on October 20th!

International Observe the Moon Night (InOMN) is a worldwide, public celebration of lunar science and exploration held annually since 2010. Tens of thousands of people participate each year, from 98 countries and 49 U.S. states (and counting!). On October 20th, your library is invited to join this world-wide celebration by hosting an InOMN event on one day each year to look at and learn about our Moon together.

InOMN is usually held in the fall, when the Moon is around first quarter. Fall in the Northern Hemisphere is generally a good time for InOMN, because of school schedules and the weather, and a first quarter Moon is visible in the afternoon and evening, a convenient time for most hosts and participants.

Earth’s Moon: The Basics

Our moon makes Earth a more livable planet by moderating our home planet’s wobble on its axis, leading to a relatively stable climate, and creating a tidal rhythm that has guided humans for thousands of years.

Quick Moon Facts
– Only celestial body that’s been visited by humans.
– Minimum temperature: -387 degrees Fahrenheit.
– Maximum temperature: 253 degrees Fahrenheit.
– Distance from the Earth: About 239,000 miles.
– “Year” (time to orbit the Earth): About 27 Earth days.
– Day: About 27 Earth days.

The Moon Illusion

Why does a rising Moon look much bigger than the same Moon seen high in the sky during the middle of the night? Turns out, it doesn’t—and we can blame the illusion on the way our eye-brain combination behaves.

Sky watchers have known this for thousands of years: moons hanging low in the sky look unnaturally big. Cameras don’t see it, but our eyes do. It’s a real illusion.

When you look at the moon, rays of moonlight converge and form an image about 0.15 mm wide in the back of your eye. High moons and low moons make the same sized spot. So why does your brain think one is bigger than the other?
