We just learned about the Milky Way
Let's learn about the North Star.
The North star is one of the brightest stars in the sky at night, and if you point toward the direction where the North star is, you will be pointing North!
Many people through the years have used the North star to find their way while traveling on land or sailing on ships at night.
It's also known as Polaris.
