As people acquainted with astrology may know, Aquarius is located between Capricornus and Pisces. Interestingly, Aquarius is found in a region of the sky known as "the Sea", where many constellations are associated with water. Although Aquarius is one of the top 10 largest constellations, it has no prominently bright stars. Its two brightest stars, Alpha and Beta Aquarii, are luminous yellow supergiants, moving through space in a plane perpendicular to the Milky Way.
To find Aquarius, you can use the Great Square of Pegasus to guide yourself towards the constellation. The pentagon found on Pisces is also located fairly close to the constellation.
This is a rough drawing of Aquarius, with its neighbouring constellations.
Two expolanet systems have been found in Aquarius. Gliese 876 is a red dwarf approximately 15 light years away from Earth, and four planets have been found to orbit it. A red dwarf is the smallest and coolest star on the Main Sequence, but is also the most common in the Milky Way. They have very low mass, hence low pressure leading to low fusion rates and a low temperature. The energy generation is the product of nuclear fusion of hydrogen into helium, and emits relatively little light, sometimes as little as 1/10000 of our Sun's.
Up next is Aquila.
