Aquarius is the 10th largest constellation in the night sky. It is best visible from latitudes 65°N to 86°S and is best seen from June to July. The brightest star in Aquarius is α Aquarii (Sadalmelik).
Aquarius is home to the Helix Nebula (NGC 7293). The Helix Nebula is the closest planetary nebula to Earth with a distance of about 300 light-years. This nebula can be difficult to see because its light is spread out over the size of a full moon.
