The Night Sky Basics

You can identify stars, planets, and constellations in the night sky.

On a clear evening in August, if you look up at the sky, you might see a bright, twinkling object that is actually the planet Jupiter, and near it, a group of stars that form the constellation of Scorpius, which is made up of many individual stars. This is an example of how to identify stars, planets, and constellations in the night sky.

To identify these objects, you need to know their characteristics: stars are usually twinkling and fixed in position, planets are brighter and move slowly across the sky, and constellations are patterns of stars that, when connected, form shapes or figures.

By learning the patterns of the constellations, you can use them as a guide to find specific stars and planets.
