The star is 66 light years distant. Between and BC, Hamal was located at the vernal equinox, the point that marks the beginning of spring. Sheratan , Beta Arietis, is a white main sequence star and a spectroscopic binary, The companion is suspected to be a G class star. Sheratan has a visual magnitude of 2.
Mesarthim , Gamma Arietis, is a triple star system. The star has also at times been referred to as the First Star in Aries because at one point it was the nearest visible star to the point of the vernal equinox.
Gamma Arietis includes a binary star system composed of two white A-type main sequence stars with apparent magnitudes of 4. The system is approximately light years distant. The brightest component is classified as an Alpha-2 Canum Venaticorum type variable star, a chemically peculiar main sequence star with strong magnetic fields and strong strontium, chromium, or silicon spectral lines.
Delta Arietis, also known as Botein, is an orange K-type giant star approximately light years from Earth. It has an apparent magnitude of 4. The star was named after the second lunar mansion division of the sky in Hindu astrology.
Bharani belongs to the spectral class B8Vn and is light years distant. Its apparent magnitude is 3. Epsilon Arietis is a binary star, approximately light years distant. It is composed of two white A-type main sequence dwarfs separated by 1. The components have apparent magnitudes of 5. A faint star in Aries, HD , along with a star in Libra, helped point the way. In , astronomers reported that these two stars had much less iron and calcium than the Sun.
It was a shocking report, because most astronomers thought that nearly all stars had the same composition. Around this time, though, they realized that the two iron-deficient stars were very old, so they had formed in the galaxy's earliest years.
Since the stars had little iron, it meant that the young galaxy itself had little iron. The galaxy has grown more iron-rich over time, though, as stars created iron and spewed it into space. So younger stars like the Sun have higher concentrations of iron and other heavy elements than older stars.
In fact, we are closer to two of the stars than those same two stars are to the remaining three stars in this constellation. Not enough Aries constellation knowledge for one day?
