[edit] 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, a recent discovery in the constellation, is one of Sun's closest neighbors around 12 light years away. It exhibits one of the largest proper motions known at about 5.06 arc seconds/yr.
[edit] Notable deep sky objects
The few deep sky objects in Aries are very dim. They include the galaxies NGC 697 (northwest of β Ari), NGC 772 (southeast of β Ari), NGC 972 (in the constellation's northern corner), and NGC 1156 (northwest of δ Ari).
[edit] 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 α Ari, λ Ari, and β Ari: α Ari being of the second magnitude and beta Arietis of the third magnitude.
The ram's body consists of the stars α Ari, η Ari, ε Ari, 41 Ari, and 35 Ari: ε Ari and 41 Ari being of the fourth magnitude.
The ram's tail consists of the stars 35 Ari, 41 Ari, and 39 Ari.
The star γ Ari, of fourth magnitude, represents the ram's front foot, and the star δ Ari, also of fourth magnitude, represents the ram's hind foot.
[edit] Astrology and religion
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 15 - May 15).
