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.
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).
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.
