A multiple star system consists of two or more stars that appear from Earth to be close to one another in the sky. [dubious – discuss] This may result from the stars actually being physically close and gravitationally bound to each other, in which case it is a physical multiple star, or this closeness may be merely apparent, in which case it is an optical multiple star [a] Physical multiple ...
Epsilon Arietis (ε Ari, ε Arietis) is the Bayer designation for a visual binary [8] star system in the northern constellation of Aries. It has a combined apparent visual magnitude of 4.63 [2] and can be seen with the naked eye, although the two components are too close together to be resolved without a telescope.
41 Arietis (abbreviated 41 Ari) is a triple star system in the northern constellation of Aries. With an apparent visual magnitude of 3.63, [ 2 ] this system is readily visible to the naked eye. It has an annual parallax shift of 19.69 mas , [ 1 ] which indicates it is at a distance of 166 light-years (51 parsecs ) from the Sun .
30 Arietis (abbreviated 30 Ari) is a 6th-apparent-magnitude multiple star system [4] in the constellation of Aries. 30 Arietis is the Flamsteed designation. 30 Arietis A and B are separated by 38.1″ or about 1,500 AU at a distance of 130 light years away.
δ Ari, called Boteïn, is a star of magnitude 4.35, 170 light-years away. It has an absolute magnitude of −0.1 and a spectral class of K2. [29] [37] ζ Arietis is a star of magnitude 4.89, 263 light-years away. Its spectral class is A0 and its absolute magnitude is 0.0. [29] [38] 14 Arietis is a star of magnitude 4.98, 288 light-years away ...
Pi Arietis, Latinized from π Arietis, is the Bayer designation for a multiple star system in the northern constellation of Aries.Based upon parallax measurements made during the Hipparcos mission, this system is approximately 800 light-years (250 parsecs) distant from Earth and has an apparent visual magnitude of 5.21.

Beta Arietis is the star's Bayer designation.It also bears the Flamsteed designation 6 Arietis.. The traditional name, Sheratan (or Sharatan, Sheratim), [8] in full Al Sharatan, is from the Arabic الشرطان aš-šaraţān "the two signs", a reference to the star having marked the northern vernal equinox together with Gamma Arietis several thousand years ago.
