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.
Which color stars have the highest surface temperature?
The hotter the star, the further up the spectrum you go. The hottest stars are the blue stars. A star appears blue once its surface temperature gets above 10,000 Kelvin, or so, a star will appear blue to our eyes.
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 star type has the highest temperature?
O stars are the hottest, with temperatures from about 20,000K up to more than 100,000K. These stars have few absorption lines, generally due to helium. These stars burn out in a few million years. B stars have temperatures between about 10,000 and 20,000K.
What 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 color is a dying star?
The dead star, called a white dwarf, can be seen at the center of the image as a white dot.

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.
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.

Is star hotter than Sun?
The sun’s surface temperature is about 5,800° Kelvin (about 10,000° Fahrenheit), and Betelgeuse is roughly half that, about 3,000° Kelvin (about 5,000° Fahrenheit). That is why it is red — red stars are cooler than the sun, blue-white stars are hotter. Betelgeuse is, however, much bigger and brighter.
What star color is 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 is the hottest star in the sky?
Sirius, with its surface at a temperature of 18,000 degrees F, is so hot that it glows blue.
What is the coldest star color?
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 least luminous star?
Let’s take a look at the smallest, least luminous stars out there: red dwarfs. A red dwarf can be as small as 7.5% the mass of the Sun, and up to 50% of the Sun’s mass. An average red dwarf has 1/10,000th the luminosity of our Sun.
What type of visible star is the coolest?
- A red dwarf is the smallest and coolest kind of star on the main sequence. …
- The coolest red dwarfs near the Sun have a surface temperature of ~2,000 K and the smallest have radii of ~9% that of the Sun, with masses about ~7.5% that of the Sun.
