Aquarius is a group of stars.
It looks like a person with a jar. The person pours water from the jar. This helps us find it in the sky. It is very old. Can you find it at night?
Aquarius is a group of stars in the sky.
Its name means "water-carrier." It looks like a person with a jar. The person pours water from the jar.
This group of stars is very old. One star in the group is very bright. It is named Sadalsuud. Many other stars live in this part of space. Some of these stars have planets around them. You can look for Aquarius at night!
Aquarius is a large group of stars.
Its name means "water-carrier." This group sits on the path of the Sun. This path is called the zodiac. Aquarius is one of the oldest zodiac groups. It is found near other watery groups. These include the whale and the fish.
Many people have told stories about these stars. In Greece, it might be a boy named Ganymede. He was a cup-carrier for the gods. In China, the stars looked like a big army. This was called the Army of Yu-Lin. The stars also looked like a water jar.
The stars in Aquarius are not very bright. The brightest star is named Sadalsuud. It is a very big, yellow star. It is much larger than our Sun. Some stars in Aquarius have planets. One star is named Gliese 876. It has four planets. One of those planets is made of rock, like Earth.

Aquarius is a large group of stars in the night sky.
It sits on the zodiac, which is the path the Sun seems to follow. Its name comes from a Latin word meaning "water-carrier" or "cup-carrier." You can recognize it by its symbol, which looks like waves of water.
Aquarius is found in a part of the sky called the Sea. This area has many other watery groups, like the fish and the whale. It is one of the oldest groups recognized by people.
Many different cultures saw different things in these stars. In ancient Babylon, the stars represented a god named Ea. He was shown holding an overflowing vase. In Egypt, people linked the stars to the yearly flooding of the Nile River. The Greeks had many stories about this group. Some said it was a boy named Ganymede who carried cups for the gods. Others thought it was a king named Cecrops I.
In China, the stars were seen very differently. Many people saw a group called the Army of Yu-Lin. This name means "feathers and forests." These stars represented light-footed soldiers from the north. This group had 45 stars, which was more than any other Chinese constellation. They also saw a water jar and even a tomb. Some stars even looked like a castle with walls.
The stars in Aquarius are not very bright. The brightest star is named Sadalsuud, or Beta Aquarii. It is a huge yellow star. It is 50 times wider than our Sun.
Another bright star is called Sadalmelik. It is also a giant star. Most of the stars in this group are not easy to see with just your eyes. They form a Y-shape that some call the "Steering Wheel."
Scientists have found many planets around these stars. These are called exoplanets. One star is named Gliese 876. It is only 15 light-years away from Earth. It has four planets orbiting it. One of those planets is a rocky world, much like our own Earth. Another star, 91 Aquarii, has a planet that is much heavier than Jupiter. Finding these worlds helps us learn more about space.
Aquarius is a large equatorial constellation located along the zodiac. The zodiac is the apparent path that the Sun follows through the sky.
Its name is Latin for "water-carrier" or "cup-carrier." This is represented by the astrological symbol ♒︎, which depicts waves of water. Aquarius is one of the oldest recognized constellations in the zodiac. It was included in the 48 constellations listed by the astronomer Ptolemy in the 2nd century. Today, it remains one of the 88 official modern constellations. It sits in a celestial region often called "the Sea." This area contains many other watery constellations, such as Cetus the whale and Pisces the fish.
Different ancient cultures saw different meanings in these stars. In Babylonian star catalogues, the constellation was known as "The Great One." It represented the god Ea, who was often shown holding an overflowing vase. In the Early Bronze Age, Aquarius contained the winter solstice. Babylonian astronomers even called a specific part of the Sun's path the "Way of Ea." In Ancient Egypt, the constellation was linked to the annual flooding of the Nile River. They believed the river would flood when Aquarius placed his jar into the water. This event signaled the beginning of spring.
Greek mythology offers several different stories for this constellation. One tradition links Aquarius to Ganymede, a beautiful youth and the son of King Tros. Zeus took Ganymede to Mount Olympus to serve as the cup-carrier for the gods. The constellation Aquila, representing an eagle, is sometimes shown snatching him away. Another myth connects the stars to Deucalion, who survived a great flood on a ship. A third tradition identifies the figure as Cecrops I, a king of Athens. He reportedly sacrificed water to the gods instead of wine.
Chinese astronomy viewed the stars through a very different lens. The stream of water was seen as the "Army of Yu-Lin," meaning "feathers and forests." This group represented light-footed soldiers from the northern empire. This was the most numerous Chinese constellation, containing 45 stars. Other parts of the constellation included the "Water Jar" asterism, known as the tomb Fenmu. Some stars also formed the ramparts of a castle called Leibizhen. The stars were organized into various lunar mansions, such as Nu, Xu, and Wei.
While the constellation is large, it does not have many very bright stars. The brightest star is Beta Aquarii, which has an apparent magnitude of 2.9. Its proper name is Sadalsuud. This is a luminous yellow supergiant star. It is approximately 50 times the diameter of our Sun. It is also about 2,200 times as luminous as the Sun and 6.4 times as massive. The second brightest star is Alpha Aquarii, also called Sadalmelik. It is a yellow supergiant that is 3,000 times as luminous as the Sun. These two stars are moving through space perpendicular to the plane of the Milky Way.
Astronomers have used modern technology to find many worlds in this region. These are called exoplanets, which are planets orbiting stars outside our solar system. As of 2013, scientists had found twelve exoplanet systems within Aquarius. One notable example is Gliese 876, located only 15 light-years from Earth. It was the first red dwarf star found to have a planetary system. This system has four planets, including one terrestrial planet that is 6.6 times the mass of Earth. Another star, 91 Aquarii, hosts a planet with a mass 2.9 times that of Jupiter.
Researchers use different methods to find these distant worlds. The transit method involves watching for a star to dim as a planet passes in front of it. This method helped discover the planet WASP-6 b. The radial velocity method looks for the tiny wobbles a planet causes in its star. This method was used to find the planet HD 210277 b in 1998. Studying these systems helps scientists understand how different types of stars and planets work together. Aquarius remains a vital area for studying the diversity of the universe.
