## What are all stars temperature?

A dark red star has a surface temperature of about 2,500 K (2,225 C and 4,040 F); a bright red star, about 3,500 K (3,225 C and 5,840 F); the sun and other yellow stars, about 5,500 K (5,225 C and 9,440 F); a blue star, about 10,000 K (9,725 C and 17,540 F) to 50,000 K (49,725 C and 89,540 F).

Are all stars the same or different?

Differences in size are optical illusions, owing to saturation of the observing cameras. Even through a telescope, most stars appear as simple points of light due to their incredible distances from us. Their differences in color and brightness are easy to see, but size is a different matter entirely.

### Are all stars actually white?

All stars are white because they emit all wavelengths. Having said that their temperatures mean that they will have a bluer or redder tint, so their spectral class will be red, orange, yellow, yellow-white, white blue-white and blue (Classes M (orC&S), K, G, F, A, B & O).

Are all stars identical explain?

As we have seen, stars are not all the same color because they do not all have identical temperatures. To define color precisely, astronomers have devised quantitative methods for characterizing the color of a star and then using those colors to determine stellar temperatures.

#### How can you tell the temperature of a star?

You can tell the approximate temperature of a star by looking at its color. The coolest stars are red, then orange, then yellow (like our Sun). Even hotter stars are white and then the hottest stars are blue! The surface temperature of our sun is 5777 Kelvins (~5000 degrees C or ~ 9940 degrees F).

Are there any stars that are the same color?

The stars show a multitude of colors, including red, orange, yellow, white, and blue. As we have seen, stars are not all the same color because they do not all have identical temperatures.

## Are there any stars hotter than the Sun?

There are many stars that are hotter than the sun — for instance, stars that burn blue are hotter than our sun! No; in fact, the Sun is a fairly faint, cool star.

What is the temperature of the hottest star?

The hottest stars have temperatures of over 40,000 K, and the coolest stars have temperatures of about 2000 K. Our Sun’s surface temperature is about 6000 K; its peak wavelength color is a slightly greenish-yellow. In space, the Sun would look white, shining with about equal amounts of reddish and bluish wavelengths of light.
