Blue stars are the hottest whilst black dwarfs are the coldest.
(However, no black dwarfs exist yet - see related question)
The stellar classification [See link] in order of temperature. Our Sun is classed as yellow.
- Blue > 30,000 Kelvin
- Blue to blue white 10,000 -> 30,000 Kelvin
- White 7,500 -> 10,000 Kelvin
- Yellowish White 6,000 -> 7,500 Kelvin
- Yellow 5,200 -> 6,000 Kelvin
- Orange 3,700 -> 5,200 Kelvin
- Red 1,000 < 3,700 Kelvin
- Brown < 1,000 Kelvin
- Black 0 Kelvin
See link [Kelvin] for conversion ratios.

Hottest Internal Temperature
However, the "hottest" star in the universe is a neutron star, based on its internal heat, which it does not radiate effectively into space. The temperature inside a newly-formed neutron star is around 1000 billion Kelvins. However, the neutrinos that it emits (in massive numbers)carry away so much energy that the temperature falls within a few years to around 1 million kelvins. Most of the radiation generated by a neutron star is X-rays. In visible light, neutron stars probably radiate approximately the same energy in all parts of the visible spectrum, and therefore would appear white.

∙ 12y agoThe coolest star is red; then yellow; then blue. Like on a fire, the bottom of the fire is really hot so its blue. In the middle of a fire, its mostly yellow. Then, on top, it has a little flame of red. :p

What color star is hotter a red star of a blue star?
The red star is the coolest and the blue star is the hottest
What is the hottest star in the solar system?
There is only one star in the solar system that is the sun. So to answer your question the sun is. The sun is a main sequence star also. The hottest stars are blue/white ones followed by stars like our own than the coolest stars are red ones
Layers of the sun in order from coolest to hottest?
The sun is a very hot star. It has 3 colors yellow,orange, and red. The hottest is red the coolest is yellow the middle is orange. Yes it is layered from coolest to hottest.
How do the blue star differ from the red star?
Blue stars are the hottest and brightest, whereas red tend to be the coolest
What is the coolest star color to the hottest?
The coolest star is red; then yellow; then blue. Like on a fire, the bottom of the fire is really hot so its blue. In the middle of a fire, its mostly yellow. Then, on top, it has a little flame of red. :p
What is the hottest star from hottest to coolest?
I don’t know
What is the color of a cool temperature star?
Red is the coolest star and blue is the hottest.
What color star is hotter a red star of a blue star?
The red star is the coolest and the blue star is the hottest

How do the blue star differ from the red star?
Blue stars are the hottest and brightest, whereas red tend to be the coolest
What do the different colors of the star mean?
The color of a star indicates its temperature. Blue or white stars are the hottest and smallest. Red or orange stars are the coolest and largest. Stars like our sun with a yellow color are medium in both size and temperature. Generally, the smaller a star is the hotter it is.
What is the coolest star color to the hottest?
The coolest star is red; then yellow; then blue. Like on a fire, the bottom of the fire is really hot so its blue. In the middle of a fire, its mostly yellow. Then, on top, it has a little flame of red. :p
The hottest stars have surface temperatures approaching 30000 K The coolest stars have temperatures of approximately 3000 K Based upon temperature alone how much more luminous are the hottest star?
They are 27,000 k more luminous then the coolest stars. Based upon temperatures then lesser star are unseen with extended lenses.
What spectral class is the hottest star under?
O. This is the class of the blue/white giants.
Size of main sequence star?
A main sequence star is NOT a TYPE of star but a period in a stars evolution. Therefore all stars from the hottest to the coolest are on the main sequence at some stage - with the exception of brown dwarfs which do not reach the main sequence.
What are the hottest and coolest stars?
the temperature of red star is minimum and maximum for blue stars . our sun is yellow colored therefore red stars are coolest than our sun . Take the example of Wolf 359 (a type of red dwarf star ) located in the constellation Leo . the temperature of photosphere of this star is about 2800 kelvin and the temperature of sun's photosphere is 5778 kelvin ( effected )
