Our solar system is located inside the star system or galaxy we call the Milky Way. At night, we can see many of the galaxy's other stars with our bare eyes. Like the Sun, these stars are large, hot objects that consist of gas and produce radiation in fusion reactions.

The stars of the night sky are divided into constellations. This makes finding different stars and planets easier.

Even though the stars of different constellations appear to be close together when viewed from the Earth, they can actually be very far from one another. Often, the stars of a constellation have nothing in common with one another except for the fact that they are perceived to be close to one another when viewed from planet Earth.
