Beta Arietis (β Ari / β Arietis) is a star in the constellation Aries, it is the Ram's second horn. It also has the traditional name Sharatan (or Sheratan or Sheratim), and the Flamsteed designation 6 Arietis.

"Al Sharatan" means "the two signs", a reference to the star having marked the vernal equinox together with its binary partner Gamma Arietis several thousand years ago.

It has an observed visual magnitude of +2.66. Its MK spectral type is A5V (white main sequence star). It is 59.6 light years from Earth.

This star is a spectroscopic binary. The companion orbits every 107 days with an unusually large eccentricity of 0.88. Based on the estimated mass of the companion, it is likely a G-class star.
