The first point of Aries, also known as the cusp of Aries, is the location of the March equinox (the vernal equinox in the northern hemisphere, and the autumnal equinox in the southern), used as a reference point in celestial coordinate systems. In diagrams using such coordinate systems, it is often indicated with the symbol ♈︎.
Lambda Arietis (λ Ari, λ Arietis) is the Bayer designation for a double star in the northern constellation of Aries.Based upon an annual parallax shift of 25.32 arcseconds, this system is approximately 129 light-years (40 parsecs) distant from Earth.
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.
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.
Delta Arietis (δ Arietis, abbreviated Delta Ari, δ Ari), officially named Botein / ˈ b oʊ t iː n /, [9] is a star in the northern constellation of Aries, 1.8 degrees north of the ecliptic. The apparent visual magnitude is 4.35, [2] so it is visible to the naked eye.
Theta Arietis, Latinised from θ Arietis, is the Bayer designation for a binary star [7] system in the northern constellation of Aries. It is faintly visible to the naked eye with an apparent visual magnitude of 5.58. [2]
