Question: What’S The Hottest Star Color?

Is star hotter than Sun?

No, the Sun is not the hottest star; there are many stars much hotter than the Sun.

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!.

Which star type lives the longest?

Generally, the bigger a star is, the faster it uses up its supply of nuclear fuel, so the longest-lived stars are among the smallest. The stars with the longest lifetimes are red dwarfs; some may be nearly as old as the universe itself.

Is our sun a red dwarf?

The sun is classified as a G-type main-sequence star, or G dwarf star, or more imprecisely, a yellow dwarf. Actually, the sun — like other G-type stars — is white, but appears yellow through Earth’s atmosphere. … The sun will puff up into a red giant and expand past the orbit of the inner planets, including Earth.

What is the order of star colors from coolest to hottest?

The color of stars from hottest to coolest is:Blue.Deep blue white.Blue white.White.Yellowish white.Pale yellow orange.Light orange red.

What is the hottest star that we know of?

The hottest known star, WR 102, is one such Wolf-Rayet, sporting a surface temperature more than 35 times hotter than the Sun.

What are the 7 types 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. O and B stars are uncommon but very bright; M stars are common but dim..

Why is a star brightest at its coolest?

In a star like the sun it takes photons a million or more years to escape from their star. As fusion reaches it’s end the star expands and cools , this allows many more photons escape . Space is awash with these photons and the star is very bright because of it.

What is the hottest star type?

O starsO 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.
