Gacrux is the traditional name for the star Gamma Crucis in the constellation of Crux (the Southern Cross) in the southern sky. The name is derived from a combination of the star's constellation (Crux) and its Bayer designation (Gamma).
Crux, also known as the Southern Cross, has a total of five major stars: Acrux, Becrux, Delta Crusis, Epsllon Crusis, and Gacrux.
The main stars of theSouthern Cross (or Crux) are:-Acrux Alpha Crucis at ~ 320 LyMimosa or Becrux Beta Crucis ~ 350 lyDelta Crucis ~ 360 lyGamma Crucis or Gacrux ~ 80 lyEpsilon Crucis ~ 380 lySee link for more information
Gamma Crucis (Gacrux) is the closest red giant to us, at a distance of about 88 light years.However, semantics aside, Arcturus is probably the closest red giant to us at a distance of about 36 light years. Although it has a spectral class of K1 putting it as an upper limit orange giant, some texts do refer to it as a red giant.
The four major stars in the constellation Crux (Latin for 'cross'), or the Southern Cross, are Alpha Crucis (Acrux), Beta Crucis (also known as Mimosa or Becrux), Gamma Crucis(Gacrux) and Delta Crucis (Decrux). Some also include Epsilon Crux (Juxta Crucem) on the list although it is not actually part of the Cross itself.
what does the word solstice mean
Gamma Crucis (Gacrux) has a spectral type of M3.It therefore has a colour of red.It is also the nearest red giant to us.
They are called Gamma Crucis and Alpha Crucis (sometimes nicknamed "Gacrux" and "Acrux")
