Aries (Latin for Ram, symbol 
, Unicode ♈) is one of the constellations of the zodiac. It lies between Pisces to the west and Taurus to the east.
Notable features
Aries' stars are rather faint except for α Ari (Hamal) and β Ari (Sharatan). Other important stars are γ Ari (Mesarthim) and δ Ari (Botein).
Teegarden's star, in Aries, is one of our sun's closest neighbours.
Notable deep sky objects
The few deep sky objects in Aries are very dim. They include the galaxies NGC 697 (northwest of β), NGC 772 (southeast of β), NGC 972 (in the constellation's northern corner), and NGC 1156 (northwest of δ).
Mythology
When including fainter stars, visible to the naked eye, the area resembles the head of a ram, having a general herbivore head shape and a spiral horn.
In Greek mythology, this is believed to represent the ram which carried Athamas's son Phrixus and daughter Helle to Colchis to escape their stepmother Ino. Helle fell off into the sea which later became the Hellespont. On reaching safety, Phrixis sacrificed the ram and hung its fleece in the Grove of Ares, where it turned to gold and later became the quest of Jason and the Argonauts. It appears that Babylonians, Greeks, Persians and Egyptians all agreed on the name of the Ram for this constellation.
The main area of the sky constituting the sign of Aries, containing part of Pisces, the Pleiades, and the constellation of Andromeda, may be the origin of the myth of the girdle of Hippolyte, which forms part of The Twelve Labours of Hercules.
Astrology
The Western astrological sign Aries of the tropical zodiac (March 21–April 19) differs from the astronomical constellation and the Hindu astrological sign of the sidereal zodiac (April 19 - May 13).
Graphic visualization
The stars of the constellation Aries can be connected in an alternative way, which graphically shows the ram running (or jumping).
The ram's head consists of the stars alpha Arietis, lambda Arietis, and beta Arietis: alpha Arietis being of the second magnitude and beta Arietis of the third magnitude.
The ram's body consists of the stars alpha Arietis, eta Arietis, epsilon Arietis, 41 Arietis, and 35 Arietis: epsilon Arietis and 41 Arietis being of the fourth magnitude.
The ram's tail consists of the stars 35 Arietis, 41 Arietis, and 39 Arietis.
The star gamma Arietis, of fourth magnitude, represents the ram's front foot, and the star delta Arietis, also of fourth magnitude, represents the ram's hind foot.
