Beta Arietis

Beta Arietis (β Ari, β Arietis) is a binary star system in the constellation Aries, marking the Ram's second horn. It has the traditional name Sheratan (or Sharatan, Sheratim), and the Flamsteed designation 6 Arietis. The traditional name, in full Al Sharatan, is from the Arabic الشراطان aš-šarāţān "the two signs", a reference to the star having marked the northern vernal equinox together with Gamma Arietis several thousand years ago.

In Chinese, 婁宿 (Lóu Su), meaning Bond (asterism), refers to an asterism consisting of β Arietis, γ Arietis and α Arietis. Consequently, β Arietis itself is known as 婁宿一 (Lóu Su yī, English: the First Star of Bond).
