'''Aquarius''' is a constellation of the zodiac, situated between Capricornus and Pisces constellations. Its name is Latin for "water-carrier" or "cup-carrier", and its symbol is â™’, a representation of water. Aquarius is one of the oldest of the recognized constellations along the zodiac (the Sun's apparent path). It was one of the 48 constellations listed by the 2nd century astronomer Ptolemy, and it remains one of the 88 modern constellations. It is found in a region often called the Sea due to its profusion of constellations with watery associations such as Cetus the whale, Pisces the fish, and Eridanus the river.
Stars
The two brightest star in the constellation are Alpha Aquarii and Beta Aquarii. Alpha Aquarii, also known as Sadalmelik comes from the Arabic for "lucky stars of the tents" Beta Aquarii, or Sadalsuud, is the brightest star in the constellation. A third star. Gamma Aquarii, also called Sadachbia, comes from the Arabic as "lucky stars of the tents".
Planetary Systems
Twelve exoplanet systems have been found in Aquarius as of 2013. Gliese 876, one of the nearest stars to Earth at a distance of 15 light-years, was the first red dwarf star to be found to possess a planetary system. It is orbited by four planets, including one terrestrial planet 6.6 times the mass of Earth. The planets vary in orbital period from 2 days to 124 days. On 23 February 2017, NASA announced that [[Ultra-cool dwarf|ultracool dwarf star]] TRAPPIST-1 in Aquarius has seven Earth-like rocky planets.
Deep sky objects
Two well-known nebulae are located in Aquarius: the Saturn Nebula and the Helix Nebula. The Saturn Nebula is called like that because it looks like planet Saturn with its rings through the telescope. One of the visible galaxies in Aquarius is NGC 7727, of particular interest for amateur astronomers who wish to discover or observe supernovae. NGC 7252 is a tangle of stars known as the Atoms-for-Peace galaxy because of its resemblance to a cartoon atom.
Meteor showers
There are three major meteor showers in Aquarius: the Eta Aquariids, the Delta Aquariids, and the Iota Aquariids. The Eta Aquariids are the strongest meteor shower radiating from Aquarius. It peaks between 5 and 6 May with a rate of approximately 35 meteors per hour. Originally discovered by Chinese astronomers in 401, Eta Aquariids can be seen coming from the Water Jar beginning on April 21 and as late as May 12. The parent body of the shower is Halley's Comet, a periodic comet.
