Which star has the highest temperature?

Sirius, with its surface at a temperature of 18,000 degrees F, is so hot that it glows blue.

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.

Which is hotter red or blue star?

The surface temperature of a star determines the color of light it emits. Blue stars are hotter than yellow stars, which are hotter than red stars.

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 is the hottest type of sun?

Eta Carinae could be as large as 180 times the radius of the Sun, and its surface temperature is 36,000-40,000 Kelvin. Just for comparison, 40,000 Kelvin is about 72,000 degrees F. So it’s the blue hypergiants, like Eta Carinae, which are probably the hottest stars in the Universe.

What is hotter the sun or lava?

But even lava can’t hold a candle to the sun! At its surface (called the “photosphere”), the sun’s temperature is a whopping 10,000° F! That’s about five times hotter than the hottest lava on Earth. … A temperature of 27 million degrees Fahrenheit is more than 12,000 times hotter than the hottest lava on Earth!

How hot is a dying star?

The green color arises from emission line transitions in the ionized gas surrounding the dim, dying star. Typically, green colors only appear from doubly ionized oxygen, requiring temperatures of ~50,000 K or above.

Which star is the coldest?

In general, a star’s temperature determines its color, from red to blue-white. Spectral types are named with a letter. The seven main types are M, K, G, F, A, B and O. M stars are the coldest stars and O stars are the hottest.

What color is the sun actually?

The color of the sun is white. The sun emits all colors of the rainbow more or less evenly and in physics, we call this combination “white”. That is why we can see so many different colors in the natural world under the illumination of sunlight.
