Draco lies in the third quadrant of the northern hemisphere and can be seen at latitudes between +90° and -15°.

It occupies an area of 1083 square degrees, making it the eight largest constellation in the night sky.

There are several myths associated with the constellation Draco. One of them is about the 12 labours of Heracles, which is represented by the neighbouring constellation Hercules. In this myth, Draco is represented as Ladon, the dragon that guarded the golden apples in the gardens of the Hesperides. However, on the other hand, the Roman mythology states that Draco was one of the Giant Titans who warred with the Olympian gods for ten years. The goddess Minerva killed him in the battle and threw him into the sky, where it froze around the North Pole. 

Draco is surrounded by constellations such as Bootes, Camelopardalis, Cepheus, Cygnus, Hercules, Lyra, Ursa Major and Ursa Minor.
