what color is the sun star
The color of the sun is white. Studying the spectra of a star can then reveal intricate details about the nature of each individual sun.

Is star hotter than Sun.
. White light is a mixture of the entire visible spectrum from red to orange to blue and purple. The hottest stars are blue with temperatures up to 40000 º C. But if the astronomers were to consider it a perfect one then the color of the sun would be considered green.
No the Sun is not the hottest star. Contrast these colors to that of our yellow Sun. It turns out that the hotter stars are whiter and cooler stars are redder.
The position of star on the H-R Diagram depends on stars temperature and brightness. Here are some interesting facts about the color of stars. The Suns color Im speaking of is not the color we see up in the sky but the color we would see if we could go into space and.
Our sun is approximately 46 billion years old and is at the midpoint of its life. Following this there are K stars which are orange in color and burn between 3000 and 5000K. These stars appear yellow in color just like the Sun which is classified as a G star.
5 rows The hottest stars have temperatures of over 40000 K and the coolest stars have temperatures of. There are two things that affect the color of a star. This is not true of the sun.
The hottest stars have temperatures of over 40000 K and the coolest stars have temperatures of about 2000 K. The color is an indication of a stars surface temperature at its photosphere. One of versions of H-R diagram is often called color-magnitude diagram but here color or color index is a number.
The lower toward horizon the Sun is the more blue is scattered and the average Suns color shifts to red. So for example cooler stars appear red and hotter stars appear blue with orange yellow and white stars in between. The sun emits all colors of the rainbow more or less evenly and in physics we call this combination white.
Its peak wavelength color is a slightly greenish-yellow. Our very own sun the star we orbit is actually a dwarf star. The light that is emitted by the Sun is actually white which consists of all the possible visible light frequencies.
The model is made in detail and meticulously it has. We have recently published an article about our own star the Sun but one thing we didnt discuss is what color the Sun is and that is because we all know the Sun is yellow. Each color of the rainbow has a different wavelength with red light.
Even though its called a yellow-dwarf star the true color of the sun is white. A stars photosphere temperature dictates its color. During sunsets the Sun would change from yellow-white to yellow to orange and sometimes red.
In space the Sun would look white shining with about equal amounts of reddish and bluish wavelengths of light. 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. This color change generated interest into its true color.
Certainly the Sun appears yellow or at times orange or even red but if we were to go up in space and somehow observe it at a properly reduced intensity level -- the Sun is way way too bright for us ironically to truly see it -- then we could declare its true color. The coolest stars in the universe are classified as M stars. So the sun actually emits energy at all wavelengths from radio to gamma ray.
This only means that the sun is white and would peak at green given the right factors. The sun is white. An astronomer wrote an article claiming the Sun to be a green star.
Our human vision and the environment we are in. A Stars Color Indicates its Surface Temperature. Looking up at the night sky we are able to see up to 4548 stars with the naked eye each coming in a variety of different colors.
The coolest stars are red then orange then yellow like our Sun. Our Suns surface temperature is about 6000 K. Then there are G stars at 5000K and 6000K.
So one might say that the sun is blue-green. Were so familiar with the Sun being yellowish-orange that astronomers will artificially change the color of their images to look more yellowy. One day an inquisitive 7 year-old simply asked me what color the Sun is.
But really the Sun looks like a pure white ball. As a stars temperature increases as a result of there being more gas in the star and hence more fuel to burn it becomes hotter. It will eventually expand into a Red Giant swallowing the inner planets until such time that it.
Yet star color is an important indicator for astronomers. Its spectrum peaks in the violet in wavelength space in the infrared in frequency space and in the green according to the wavelength-space blackbody approximation. There are many stars much hotter than the Sun.
Ladies and GentlemanI present to you today the racing Subaru Impreza 555 in civilian color ie. Although not as exciting the ultimate truth is. But as can be seen in the image above it emits most of its energy around 500 nm which is close to blue-green light.
The peak wavelength in a spectrum also generally determines an objects apparent colour. The sun is more of a non-ideal blackbody. When we make use of a prism sunlight can be broken down into all colors of the rainbow which are red orange yellow green blue indigo and violet.
The color components of sunlight are so close enough to being present in equal amounts that it is much more correct to say that the sun is. For the Sun the spectrum actually peaks at a wavelength that we would normally describe as green. Its colour changes from orange through yellow to white.
