What is syzygy?

A syzygy is when three things line up perfectly, just like when you and your friends all stand in a straight line for a photo.

Like When the Sun, Moon, and Earth Line Up

Imagine it’s a sunny day, and you're playing with a ball (the Moon) that's shining light on you (the Earth). Now, if someone (the Sun) comes behind you and shines light on the ball too, poof, you get a syzygy!

This happens when the Sun, Moon, and Earth all line up in a straight path. Sometimes it makes really cool things happen, like big tides or even a total eclipse, when one covers the other completely, just like how your shadow gets bigger when you stand closer to a light.

A Syzygy Happens All Around Us

You can make a syzygy at home too! If you put three toys in a straight line on the floor and shine a flashlight from one end, there you go! You’ve made your own syzygy, just like the ones in space. A syzygy is when three things line up perfectly, just like when you and your friends all stand in a straight line for a photo.
