The main types of star in order of temperature are A, F, G, K, M (A is the hottest). A G2 star is two tenths of the way from G to K, in other words slightly cooler than the standard G-type.
Our sun is a yellow main sequence star of spectral type G2 V
See related link and you'll be able to work it out.
G2 ... or "yellow dwarf" (its really white - by the definition of "white")
It is a very normal type of star with a G2 spectrum and absolute magnitude of 4.5.
The Sun is classified as a G-type star. Specifically, it is a G2V star, which means it is a main-sequence star like other G-type stars, such as Alpha Centauri A.
A main-sequence G2 star refers to a star that is in the main sequence phase of its life cycle and has a spectral type of G2. The G2 classification refers to the star's surface temperature and color, with G2 stars like our Sun being yellow-white in color. These stars are fusing hydrogen in their cores and are stable in their energy production.
Because the sun is a star, a yellow dwarf star (spectral type G2) to be exact.
Our sun is a yellow main sequence star of spectral type G2 V
See related link and you'll be able to work it out.
Earth's star is what we call the Sun, and it is a main-sequence star with a G2 spectrum and an absolute magnitude of +4.7.
Sadalmelik (Alpha Aquarii) is a G2 spectral type star; a yellowish white giant star.

The "levels" are 1-50 The Ranks go(from least to greatest): (G2,G3- means Grade 2, Grade 3) * Recruit * Apprentice-G2 * Private-G2 * Corporal-G2 * Sergeant-G2-G3 * Gunnery Sergeant-G2-G3-Master Gunnery Sergeant (>Lvl 10) * Lieutenant-G2-G3-First Lieutenant (LvL 10) * Captain-G2-G3-Staff Captain (LvL 20) * Major-G2-G3-Field Major (LvL 30) * Commander-G2-G3-Strike Commander (LvL 35) * Colonel-G2-G3-Force Colonel (LvL 40) * Brigadier-G2-G3-Brigadier General (LvL 45) * General-G2-G3-Five Star General (LvL 50)
Alpha Aquarii -also known as Sadalmelik- is a supergiant star in the Aquarius constellation. It has a stellar classification of G2 lb.
You probably mean G2. G stands for good. 2 is the quality on a scale of 1 to 70. G2 is almost the lowest possible condition for a coin.
The solar system has only one star, the Sun, a yellow star with a G2 spectrum and an absolute magnitude of 4.7.
Yes, the sun is classified as a G2V star. This means it is a main-sequence star of spectral type G, and the "V" indicates that it is in the main sequence phase of its life cycle.
