Aries Stars Constellation is a Northern constellation located between Pisces the Fish and Taurus the Bull.
Aries is also bordered by Cetus the Whale (or Sea-Monster), Perseus the Hero, Triangulum the Triangle and Andromeda the Chained Princess. This is one of the oldest and most revered of all constellations. The ancient Babylonians, Egyptians, Persians and Greeks all called this group of stars "The Ram."
It is the Zodiac's first constellation since the Sun was, at one time, entering Aries on the day of the Vernal Equinox...the moment when it crosses from the Southern to the Northern half of the celestial sphere.
However, because of the Earth's precession, the Sun is now in Pisces at the Vernal Equinox. Nevertheless, Aries constellation is still considered to be the symbolic first constellation of the Zodiac and Right Ascension continues to be measured from the first point of Aries.
Stars in Aries constellation can be seen in the Northern Hemisphere during the late Winter and early Spring.
The constellation itself is well known and not difficult to locate in the night sky, but has few objects of interest.
Nevertheless, it is visible in both the Northern and Southern hemispheres from September through February.
The head of the ram is marked by the first bright star due West of the Pleiades (a cluster of seven stars in Taurus). This star is Alpha Arietis, known as Hamal (from the Arabic for "lamb"). Just to the Southwest lie two bright stars, Beta and Gamma Arietis (also known as Sheratan and Mesarthim), which represent the ram's horns.
To the Northeast of Hamal is a somewhat dimmer star that marks the ram's back, and Southeast of that point is Delta Arietis (also known as Botein), which represents the tail.
Perhaps the best known stars in the constellation of Aries are Sheratan and Hamal.
One of its major attractions is the Gamma Arietis, a beautiful double star, which was discovered quite by chance in 1664 when astronomer, Robert Hooke, was following the motion of a comet. Gamma Arietis is one of the earliest double stars on record to have been found with the aid of a telescope.
