what color is the sun star
So one might say that the sun is blue-green. The reason that the Sun looks yellow to us is because the Earths atmosphere scatters higher wavelength colors like red orange and yellow less easily.

It was created by astronomers Ejnar Hertzsprung and Henry Norris Russell about 1910 and can be used to chart the life cycle or evolution of a star.
. If the Sun were cooler it would give off light more on the red end of the spectrum and if the Sun were hotter it would look more blue. A higher surface temperature would result in a shorter maximum wavelength and our sun might peak in the blue or violet part of the spectrum or even the ultra violet. The Sun is shines with a yellow -ish colour and is about 6000 C.
Shortly thereafter this same region of the sun sent a coronal mass ejection out into space. The Sun at the heart of our solar system is a yellow dwarf star a hot ball of glowing gases. Very massive stars which can be over ten times the mass of the Sun are the hottest and usually glow blue.
It is whiter in colour with a slight tint of yellow. The color indicates the stars temperature in its photosphere the layer where the star emits. For the Sun the spectrum actually peaks at a wavelength that we would normally describe as green.
So for example cooler stars appear red and hotter stars appear blue with orange yellow and white stars in between. Even though its called a yellow-dwarf star the true color of the sun is white. Stars are different colors white blue yellow orange and red.
The sun and stars with similar temperatures are yellow when observed from the earth and that is why they are often represented with this color. Can dwarf stars Be Blue. That is because the short-wavelength colors green blue violet are scattered away by the Earths atmosphere.
Our sun is approximately 46 billion years old and is at the midpoint of its life. A blue dwarf is a predicted class of star that develops from a red dwarf after it has exhausted much of its hydrogen fuel supply. There is no contrast to make it look more yellow.
Hence these wavelengths are what we see which is why the Sun appears yellow. The real color of the sun is white. The thicker layer of air means only the reds yellows and oranges wavelengths get through the atmosphere to our eyes.
This maximum radiation frequency is governed by the suns surface temperature around 5800K. The Sun is almost a perfect sphere. This makes the Sun a relatively cool star.
Our very own sun the star we orbit is actually a dwarf star. It formed approximately 46 billion a 14 22 years ago from the gravitational collapse of matter within a region of a large molecular cloud. Its gravity holds the solar system together.
However you can also find diagrams for which real stellar colors are kept and in those diagrams Sun will be a white point. This group of stars are relatively small containing between 80 and 100 the mass of the Sun. A red dwarf star is another type of dwarf star but this one has a red color to it which is based on the fact that its a bit cooler than other stars.
What is the color of the sun. The temperature of a star depends on how much mass it has. The color of a star depends on its surface temperatureThis white light coming off of the Sun is because its temperature is 6 000 Kelvin.
According to their system of classification the Sun is known as a yellow dwarf star. What color is a dying star. The energy created by the Suns core is nuclear fusion.
Some stars with temperatures a bit higher than our Sun emit red green and blue light in about equal measure and so they glow white. It will eventually expand into a Red Giant swallowing the inner planets until such time that it. Compared to the Sun being observed from Earth it would look more whitish and bright.
The Sun and stars with similar temperatures are yellow when observed from the Earth and that is why they are often represented with this color and called yellow dwarfs. That is because there is no atmosphere to disseminate the blue and the background from space is black. The Sun is actually white.
Stars emit colors of many different wavelengths but the wavelength of light where a stars emission is concentrated is related to the stars temperature the hotter the star the more blue it is the cooler the star the more red it is. The Hertzsprung-Russell diagram is a graph that plots the temperature of a star against its absolute magnitude or luminosity. When the sun is low in the sky at sunrise or sunset it can seem yellow orange or red.
As such it is informally and not completely accurately referred to as a yellow dwarf its light is actually white. We see it as yellow because of the Earths atmosphere. The gif below explains the relation between star temperature and color.
The peak wavelength in a spectrum also generally determines an objects apparent colour. The Sun is a G-type main-sequence star G2V. What color is the coolest star on the HR diagram.
As you can see from the gif above as the emission spectra of cold stars peaks in the infrared there is more red visible light than blue. Many photos present the Sun as yellow this is because we are very familiar with this color however from space the Suns true color is white. Interestingly the color of the sun is very important to astronomers.
The largest R136a1 is approximately 260 times the Suns mass the light from these hot new. So that is one way in which older stars are redder than young stars. White light is a mixture of the entire visible spectrum from red to orange to blue and purple.
Although we have linked the colors yellow orange and red with that of the sun when viewed through outer space the sun is a brilliant white.
