The Sun has a G-type spectrum. All stars with type A and F spectrums are hotter, like Sirius for example, as well as the very hot but not numerous B-type and a few others. The order is B-A-F-G-K-M.

Do red stars have higher surface temperatures than blue stars?
No. Red stars have the lowest surface temperatures while blue stars have the highest.
Which stars have the highest surface temperatures red star or blue stars?
Blue stars have the highest surface temperature, at over 7,500 Kelvin. The surface temperature of red stars is less than 5,000 Kelvin.
What are the coolest star?
The coolest active stars are the red dwarfs, with surface temperatures that are lower than 4000 Kelvin.
Is the surface temperature of white dwarf stars higher or lower than red super giants?
Yes dwarf has higher temperature
What relationship do you see between a star's color and its temperature?
The visible spectrum, as it goes from red to blue, refects higher energies and shorter wavelengths, that are produced by progressively higher temperatures. So, bluish stars are hotter than reddish stars.
Do red stars have higher surface temperatures than blue stars?
No. Red stars have the lowest surface temperatures while blue stars have the highest.
Why is the surface temperature of Venus higher than the surface temperatures of the other inner?
The surface temperature of Venus is higher than the surface temperatures of the other inner planets because of its thick atmosphere.

Is the surface temperature of white dwarf stars higher or lower than red super giants?
Yes dwarf has higher temperature
Does a red star have a higher surface temperature than a blue star?
Yes, the blue stars surface temperature can reach over 25,000K
Is the surface temperature of white dwarf stars higher or lower than a red super giants?
Yes dwarf has higher temperature
Why do bigger stars lose their gas more quickly?
Larger stars have more mass and stronger gravity than small ones, which leads to greater pressure and thus higher temperatures at their cores, which causes hydrogen to fuse at a higher rate.

The visible spectrum, as it goes from red to blue, refects higher energies and shorter wavelengths, that are produced by progressively higher temperatures. So, bluish stars are hotter than reddish stars.
Will a stars lifecycle be shorter or longer if its mass is greater?
Shorter. More massive stars have much higher temperatures and pressures. Although they have a lot more fuel, it is consumed at a much higher rate than lower mass stars. They burn very brightly and hot, but for less time.
How hot are O stars?
Class O stars are the hottest of stars with temperatures greater than 30,000oK
