Type O stars have the highest surface temperatures and can be as hot as 30,000 Kelvins.
Which color stars have the highest surface temperature quizlet?
Consider the four stars shown following. Rank the stars based on their surface temperature from highest to lowest. (Notice that temperature is related to color, and follows the order of the colors in the rainbow: Blue (or violet) stars are the hottest, while red stars are the coolest.)
Which stars have the highest surface temperature red stars or blue stars?
Red stars are cooler than the sun, with surface temperatures of 3,500 K for a bright red star and 2,500 K for a dark red star. The hottest stars are blue, with their surface temperatures falling anywhere between 10,000 K and 50,000 K.
What is the correct order of stars from hottest to coolest?
Explanation: According to the stellar classification stars are grouped into seven main types according to their temperature that are O, B, A, F, G, K, and M. M are the coldest stars and O are the hottest stars. The color of these groups are in order- blue, blue-white, white, yellow-white, yellow, orange and red.
Which color has the highest surface temperature?
Answer Expert Verified
Stars of blue color have the highest surface temperature. Scientists have been able to approximately determine the temperature of stars based on the spectrum of a black body, which absorbs all radiation.
Which star has the lowest surface temperature?
Which star has the lowest surface temperature? Antares, with a spectral type of M1 (the furthest from O in OBAFGKM), has the lowest surface temperature.
What star has a temperature of 6000K?
The hottest stars emit much of their energy in the ultraviolet and appear to be electric blue, like an arc-welder’s torch. The star Sirius is a good example of a blue star.

Colors and Temperatures.
| Surface Temperature | Star | Color |
|---|---|---|
| 6000K | Sun | Yellow-white |
| 4000K | Arcturus | Peach |
| 3000K | Betelgeuse | Red |
What color stars are the coolest?
Red stars are the coolest. Yellow stars are hotter than red stars. White stars are hotter than red and yellow. Blue stars are the hottest stars of all.
What type of visible stars is the coolest?
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. Our own Sun is a G star.
Are blue stars older than Red Stars?
Stars emit colors of many different wavelengths, but the wavelength of light where a star’s emission is concentrated is related to the star’s temperature – the hotter the star, the more blue it is; the cooler the star, the more red it is. … So that is one way in which older stars are redder than young stars.
What are the hottest stars in the universe?
The hottest known star, WR 102, is one such Wolf-Rayet, sporting a surface temperature more than 35 times hotter than the Sun. Like Baskin-Robbins, Wolf-Rayet stars come in a variety of flavors.
Which star has more mass?
R136a1. The star R136a1 currently holds the record as the most massive star known to exist in the universe. It’s more than 265 times the mass of our Sun, more than double most stars on this list.
What color is the coldest star?
Stars have different colors, which are indicators of temperature. The hottest stars tend to appear blue or blue-white, whereas the coolest stars are red.
What is the hottest color?
While blue represents cooler colors to most, it is the opposite in fires, meaning they are the hottest flames. When all flame colors combine, the color is white-blue which is the hottest. Most fires are the result of a chemical reaction between a fuel and oxygen called combustion.
Why is Blue Star hotter than red?
Well, to answer this, a shorter wavelength means greater energy. This is important because if you look at the spectrum, blue photons have more eery than red photons so the blue star generates more energy and more heat than the red. To answer simply, the red stars are lower in temperature than the blue stars.
What are the 7 spectral classes of stars?
Stars are classified by their spectra (the elements that they absorb) and their temperature. There are seven main types of stars. In order of decreasing temperature, O, B, A, F, G, K, and M.
