==Stars and other features==
In addition to the stars that make up the constellation, Draco has several other notable astronomical features. The [[Cat's Eye Nebula]] (NGC 6543), a [[planetary nebula]] some 3300 light years distant, is one of the deep sky objects located within the constellation. Others include the '''Draco Dwarf Galaxy''', a satellite of the [[Milky Way]], and the galaxy '''NGC 5866''', the latter located some 50 million light years away.

Despite [[Thuban]] having the alpha [[Bayer designation]], usually reserved for the brightest stars in a constellation, it is [[Eltanin]] (Gamma Draconis) that is the brightest star in Draco, with an apparent magnitude of 2.24.
