The Sun is a as a G2V type star, a yellow dwarf and a main sequence star. Stars are classified by their spectra(the elements that they absorb) and their temperature. There are seven main types of stars. In order of decreasing temperature, O, B, A, F, G, K, and M
Our Sun has a spectral class of G2V.
Alpha Centauri A - It is 4.365 light years away and has a spectral class of G2V the same as our Sun
Spectral class is classification of stars by their external features..Like light,temperature etc..
G2V; can be interpreted as yellow two tenths towards orange main sequence star
M2 variable.
Our Sun has a spectral class of G2V.
Alpha Centauri A - It is 4.365 light years away and has a spectral class of G2V the same as our Sun
Based on what? Luminosity, distance or spectral class?
The spectral class is A0Va.
Our Sun has a spectral class of G (Yellow dwarf). About 1 in 13 stars, in our solar neighbourhood are within this class
Antares has a spectral class of M1LB.
Eta Pegasi (Matar) is a star in the constellation Pegasus.It has a spectral type of G2 so it has a colour of yellow.Matar has the same spectral class as our Sun
Spectral class Y, which is typical of "brown dwarf" stars.
Spectral class is classification of stars by their external features..Like light,temperature etc..
Sirius is a double star. The brighter component ... the one you actually notice in the night sky ... is spectral class A1V. The faint 'secondary' component is spectral class DA2.
