Simply so, what kind of a star is the sun?
yellow dwarf
One may also ask, what is a Class M star? Class M Stars are the most common type of stars in the galaxy, composing about 76% of the main sequence stars in our region of the galaxy. They are the next category colder than a Class K Star, and burn red as a result. Class M stars come in a variety of sizes and specifications: M V Stars, also known as Red Dwarfs.
Keeping this in consideration, what does g2v stand for?
A G-type main-sequence star (Spectral type: G-V), often (and imprecisely) called a yellow dwarf, or G dwarf star, is a main-sequence star (luminosity class V) of spectral type G. Such a star has about 0.84 to 1.15 solar masses and surface temperature of between 5,300 and 6,000 K. , Tables VII, VIII.
Is the sun a main sequence star?
Main sequence stars fuse hydrogen atoms to form helium atoms in their cores. About 90 percent of the stars in the universe, including the sun, are main sequence stars. These stars can range from about a tenth of the mass of the sun to up to 200 times as massive. Stars start their lives as clouds of dust and gas.

How do stars die?
Stars die because they exhaust their nuclear fuel. Really massive stars use up their hydrogen fuel quickly, but are hot enough to fuse heavier elements such as helium and carbon. Once there is no fuel left, the star collapses and the outer layers explode as a 'supernova'.What stage of life is the sun in?
The Sun, like most stars in the Universe, is on the main sequence stage of its life, during which nuclear fusion reactions in its core fuse hydrogen into helium.What color is the hottest star?
blue
What is the closest star to Earth?
Alpha Centauri A
How common are G stars?
G stars within 100 light-years. their relative abundance. As many as 512 or more stars of spectral type "G" (not including white dwarf stellar remnants) are currently believed to be located within 100 light-years or (or 30.7 parsecs) of Sol -- including Sol itself.Which is the biggest known star?
UY Scuti
How many suns are there in the whole universe?
For many years scientists have studied our own solar system. But until the last few years, we knew of no other solar systems. This may seem surprising, as the Sun is one of about 200 billion stars (or perhaps more) just in the Milky Way galaxy alone.Is Sun a red dwarf?
The sun is classified as a G-type main-sequence star, or G dwarf star, or more imprecisely, a yellow dwarf. Actually, the sun — like other G-type stars — is white, but appears yellow through Earth's atmosphere. The sun will puff up into a red giant and expand past the orbit of the inner planets, including Earth.Is the sun a supergiant?
Supergiant Star. If our Sun is an average sized star, there are some true monsters out there. They're the supergiant stars, and they come in two flavors: red and blue.Is the sun a red giant?
In approximately 5 billion years, the sun will begin the helium-burning process, turning into a red giant star. When it expands, its outer layers will consume Mercury and Venus, and reach Earth.Is the sun a g2?
Sun is classified as a G2 V star, with G2 standing for the second hottest stars of the yellow G class—of surface temperature about 5,800 kelvins (K)—and the V representing a main sequence, or dwarf, star, the typical star for this temperature class.Is the sun a white dwarf?
A low or medium mass star (with mass less than about 8 times the mass of our Sun) will become a white dwarf. A typical white dwarf is about as massive as the Sun, yet only slightly bigger than the Earth. This makes white dwarfs one of the densest forms of matter, surpassed only by neutron stars and black holes.Where are stars born?
Stars are born within the clouds of dust and scattered throughout most galaxies. A familiar example of such as a dust cloud is the Orion Nebula. Turbulence deep within these clouds gives rise to knots with sufficient mass that the gas and dust can begin to collapse under its own gravitational attraction.Are there planets around K type stars?
Potentially habitable planets around K-type main-sequence stars. A super-Earth orbiting a K-type main-sequence star called HD 85512 b appears to have habitability potential. Kepler-62 is an example of a discovery by Kepler of a system consisting of a K-type dwarf with potentially habitable planets orbiting it.What is the sun made of?
The Sun is a huge, glowing sphere of hot gas. Most of this gas is hydrogen (about 70%) and helium (about 28%). Carbon, nitrogen and oxygen make up 1.5% and the other 0.5% is made up of small amounts of many other elements such as neon, iron, silicon, magnesium and sulfur.How big is a red dwarf star?
Red Dwarf. Red dwarfs are small (0.08-0.5 M⊙), low-surface temperature (2500-4000 K) Main Sequence stars with a spectral type of K or M. It is their low temperature which dictates their red appearance. Their small diameter (typically a few tenths that of the Sun) means that they are also faint.What happens to Brown Dwarfs?
Brown dwarfs are objects which are too large to be called planets and too small to be stars. Brown dwarfs are thought to form in the same way that stars do - from a collapsing cloud of gas and dust. However, as the cloud collapses, it does not form an object which is dense enough at its core to trigger nuclear fusion.What is the brightest star?
Sirius A
