A stars color is determined mainly by it's surface temperature. They tend to range from Blue (hottest) thru white and yellow to red (coolest). One thing to bear in mind tho is that a Red Giant star, for example, produces more heat than a smaller yellow star but because the star is much bigger the heat is more spread out (because the surface area is so much bigger) and therefore it appears red.

What is the temperatures of stars from hottest to coldest?
The temperatures of stars from hottest to coldest are blue stars, white stars, yellow stars (like our sun), orange stars, and red stars. Blue stars can have surface temperatures exceeding 30,000K, while red stars typically have surface temperatures around 3,000K.
What color is an O star?
An O star is typically blue in color, and is one of the hottest types of stars with surface temperatures exceeding 30,000 K. The color of a star is a result of its temperature, with hotter stars appearing blue and cooler stars appearing red.
Is the sun hotter or cooler than red and blue stars?
The sun is hotter than red stars but cooler than blue stars,
What are the hottest stars from hottest to coolest in order?
The hottest stars are blue in color and have surface temperatures exceeding 30,000 K. Following the sequence: O, B, A, F, G, K, M (from hottest to coolest), O-type stars are the hottest, with temperatures reaching over 30,000 K, while M-type stars are the coolest with temperatures around 2,400 K.
What spectral class of stars are the hotteset?
Type-O are the hottest but there are very few. Then type-B, there are more of them but still not a lot. Then you have type-A, which are very common, then F, then G like the Sun, then K and then the coolest common ones, type M which are the red stars like Betelgeuse.
Is the hottest star the red star?
Ironically the blue stars are the hottest considering blue is usually a "cool" color.
What color star is hotter a red star of a blue star?
A blue star is hotter than a red star. Blue stars have higher surface temperatures, typically exceeding 10,000 Kelvin, while red stars have lower surface temperatures, usually below 4,000 Kelvin. The color of a star is an indication of its temperature, with blue stars being the hottest and red stars being the coolest.
How do scientists know that Rigel is the hottest star?
Rigel is a blue-white star wich indicates that is a very hot star. you might think red stars are the hottest but no, the hottest are blue-white.
Which star is hotter red or orange?

How do the blue star differ from the red star?
Blue stars are hotter, larger, and more luminous than red stars. They have shorter lifespans due to their high energy output. Red stars are cooler, smaller, and less luminous, and they have longer lifespans.
What is the temperatures of stars from hottest to coldest?
The temperatures of stars from hottest to coldest are blue stars, white stars, yellow stars (like our sun), orange stars, and red stars. Blue stars can have surface temperatures exceeding 30,000K, while red stars typically have surface temperatures around 3,000K.
Are blue-white stars the coolest?
