Which star is the coldest?
Y dwarfs are the coldest members of star-like bodies known as brown dwarfs, which are odd objects sometimes known as failed stars. So far, WISE has helped find 100 new brown dwarfs.
What are the coolest stars called?
One way that stars are categorized is by temperature. Since the temperature of a star can determine its visual color, this category scheme is known as spectral type. The main categories of spectral type are M, K, G, F, A, B, and O. The coolest stars (red dwarfs) being M, and the hottest stars being O.
Are M type stars the coolest?
M stars are coolest and most common stars in the Universe. M stars range in temperature from 2,500 Kelvin and go all the way up to 3,500 Kelvin.
What color star is the coldest?
red The colour provides a fundamental piece of data in stellar astrophysics—the surface temperature of the star. The hottest stars are blue and the coldest are red, contrary to the use of colours in art and in our daily experience.
Where are the coolest stars located?
Hot stars inhabit the left hand side of the diagram, cool stars the right hand side. Bright stars at the top, faint stars at the bottom.
What is the second coldest star?

What is a G2 type star?
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.
