A yellow dwarf star, is a star on the main sequence that has a temperature range of between 5,200 to 6,000 Kelvin. It has a spectral class of G or possibly F.
Our Sun is a yellow dwarf - much as you may not believe it, it is a dwarf compared to other stars!!

There are several kinds of dwarf stars, and I suggest you look them up in the Wikipedia or some other encyclopedia, for more details. Briefly:

A dwarf star is any main sequence star that has a luminosity class of V. [See related link]
Our Sun is a yellow dwarf, although it may not look dwarfish!
Other dwarf stars are:
The sun is considered a yellow dwarf, although this is a complete misnomer, as it is larger and brighter than over 3/4 of the stars in the galaxy and is fated to become a red giant after this part of it's life cycle.
The term "yellow dwarf" is somewhat antiquated, as it was coined before the space age, when we were able to find out not only that our sun is actually relatively big and will be getting much bigger, but also that when seen from space (as opposed to through the atmosphere), it is not yellow at all, but is instead white.
So, in short, it is not yellow, and it is not a dwarf, but it is still considered to be a "yellow dwarf".
The Sun is categorized as a yellow dwarf, stellar class G2V. The "V" part is what
indicates that it's a "dwarf" (main sequence) star.
The terminology is a little confusing. "Dwarf" is used for historical reasons and only
incidentally refers to size; for the hottest stars, there's very little size difference
between dwarfs and giants.
Also, there's no "medium" or "normal" category. Stars are white dwarfs, subdwarfs,
dwarfs, subgiants, giants, bright giants, supergiants, or hypergiants. Dwarfs are
by far the most common type of star.
They give off so much light, because technically they are of the same make as our sun, just smaller, so they give out around the same amount, although a bit less probably, depending on the star, as our sun
There are different classes of star that can be called dwarf stars. Some are ordinary stars that have masses similar to or less than that of the sun. These include red dwarfs, orange dwarfs, and yellow dwarfs. A brown dwarf is a star that failed to initiate nuclear fusion. A white dwarf is the collapsed remnant of a low to medium mass star.
No, it is impossible for the sun to be a brown dwarf. Brown dwarfs are bodies that are too large to be planets, yet too small to be a star. The Sun is a fully-functioning star; it is hundreds of times larger than Jupiter. Brown dwarfs are only about 40 times larger than Jupiter.
Yes, the Sun is what astronomers call a yellow dwarf, stellar class G2V. The "V" part is what indicates that it's a "dwarf" (main sequence) star.

All stars are smaller than Solar Systems. A star is what keeps everything withen a system with it's immense gravitational pull. Stars also vary in size from giant superstars to small dwarf stars our Sun, Sol, is a midsized middle aged star.
Then, depending on the remaining mass of the star, it will collapse into a white dwarf, a neutron star (aka pulsar), or a black hole.Then, depending on the remaining mass of the star, it will collapse into a white dwarf, a neutron star (aka pulsar), or a black hole.Then, depending on the remaining mass of the star, it will collapse into a white dwarf, a neutron star (aka pulsar), or a black hole.Then, depending on the remaining mass of the star, it will collapse into a white dwarf, a neutron star (aka pulsar), or a black hole.
White Dwarf, Sun, Red Giant, Supernova
Black holes can only be created when a super massive star explodes. The star has to be 10x bigger then our sun to make a black hole. When our sun explodes it will just create a white dwarf. When the star runs out of hydrogen and helium it explodes and creates a black hole.
It is a white dwarf.
Depends what type of dwarf star. - Our Sun is a yellow dwarf.
its not a massive or a dwarf star
It is impossible for the sun to be a dwarf galaxy because the sun is a star. But if you're asking if it's a dwarf star, then no, otherwise we'd be dead.
the sun is NOT a dwarf star, it is a g-type star. a dwarf is a s-type starThe Sun is a G2V star G2 means the second hottest of the yellow G class and V (the Roman numeral five) identifies the Sun as a main sequence DWARF STAR (so yes it is a dwarf star) A star with spectral S is a late-type giant star (similar to class K5-M).
Our Sun is a yellow dwarf star.
The sun is neither a supernova nor a white dwarf. The sun is a main sequence star. A supernova is not a kind of star: it is the explosion of a massive star.
The sun is actually a main sequence star.
The Sun is a yellow dwarf star.
G2V Otherwise known as a yellow dwarf
Many stars are bigger than the sun. In fact the sun is called a yellow dwarf, or a G dwarf star meaning it is relatively small (i.e. a dwarf) compared to the "average star" in our galaxy.
Blue dwarf diameter(sun=1)=4 times the sun's Blue dwarf mass(sun=1)=10 times sun's
Proxima centauri is the closest red dwarf star and is the closest star
