30 June - NATIONAL METEOR WATCH DAY

Meteor Watch Day is observed every year on June 30th in the USA. Also known as National Meteor Day, on a cloudless night, people turn their eyes to the heavens in hopes of spotting the glow of a falling star. 

Daily there are millions of meteors that occur in the Earth’s atmosphere.

When space debris, such as pieces of rock, enter the Earth’s atmosphere the friction causes the surrounding air to become scorching hot. This “shooting star” streaking through the sky surrounded by flaming hot air is a meteor.

The majority of the meteoroids that cause meteors are only the size of a pebble.

Meteors sometimes occur in showers. It’s an excellent time to plan for a meteor-watching party. Whether we catch a few stray falling stars or witness an entire meteor shower, this day calls for an evening with friends and family under the stars. Identify the constellations while waiting to make a wish or two. Sounds like a romantic night, as well.
