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
The Sun is a G-type main-sequence star, also known as a G2V star. This classification places the Sun in the "yellow dwarf" category.
Alpha Centauri A is a nearby star that is in the same spectral class as the sun, which is G-class. It is the primary component of the Alpha Centauri star system, located about 4.37 light-years away from Earth.
See related link and you'll be able to work it out.
G2V; can be interpreted as yellow two tenths towards orange main sequence star
Our Sun belongs to the G spectral class, specifically classified as G2V. This classification indicates that it is a yellow dwarf star, characterized by its surface temperature of around 5,500 degrees Celsius (about 5,800 Kelvin) and its moderate brightness. The "V" denotes that it is a main-sequence star, undergoing hydrogen fusion in its core.

Spectral class Y, which is typical of "brown dwarf" stars.
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
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.
