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.
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.
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.

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.
