Which has the highest surface temperature red star white star or blue star?

Answer 1

The hottest stars are O type stars (aka Blue Giants) which have a temperature of greater than 30,000 kelvin and will have a colour of, as the name suggests, blue!

The hottest stellar remnant in the universe is the Neutron Star burning on creation at a temperature of over 1 billion degrees kelvin. However, the huge number of neutrinos it emits carries away so much energy that the temperature falls within a few years to around 1 million kelvins. It would appear white to the eye. The hottest stars in the galaxy are blue stars. The hottest stars in the galaxy are blue stars.

Answer 2

Blue stars typically have the highest surface temperature compared to red and white stars. Blue stars are very hot and emit large amounts of energy, which is why they appear blue due to their intense heat. Red stars, on the other hand, have cooler surface temperatures and emit lower energy levels.

Answer 3

A blue star is the hottest.

I've yet to see a green star.

(The usual cause of star color is cavity/blackbody radiation. It turns out that by the time there's enough intensity in the green region for the star to stop looking yellow, there's also enough intensity in the blue region for it to start looking white, so a deep, intense green isn't really an option, though a star right on the border between yellow-white and white might look very faintly greenish.)

Answer 4

I believe it will be the blue star. The blue end of the spectrum of electromagnetic energy is the higher energy end, and the red end is the lower energy end. Beyond 'blue' in terms of increasing energy will be ultraviolet, not white.

Answer 5

The colour temperature scale is as follows :-

• Classification - Colour - Temperature
• O - Blue - Over 30,000 Kelvin
• B - White/Blue - 10,000 to 30,000 K
• A - White - 7,500 to 10,000 K
• F - Yellow/White - 6,000 to 7,500 K
• G - Yellow - 5,200 to 6,000 K
• K - Orange - 3,700 to 5,500 K
• M - Red - Under 3,700 K

Answer 6

This is an odd question. If you are asking, "What visible color of a star represents the hottest temperature", then answer is blue. If you are asking, "what color represents the hottest temperature on a planet or other non-star body", then that would depend on how your measuring equipment graphically represents the hottest temperature. Heat is equivelent to infrared light. This infrared light isn't visible by the naked eye so astronomical equipment must measure the intensity of infrared and represent it on a computer screen with a false visible color.

Answer 7

Blue Then white than yellow than red. The coolest live the longest though. The hottest are bigger that the cooler ones. When the blue ones die they turn into black holes. The white ones turn into Neutron stars and the yellow and red stars turn into white dwarfs.

Answer 8

Blue - with a surface temperature greater than 30,000 Kelvin

Answer 9

Cool stars appear red. That is because most of their energy is emitted in the red and infrared region of the electromagnetic spectrum.

Answer 10

O and B stars will have a higher temperature than other stars.
