The color of a star comes from its temperature. The coolest stars appear red, while the hottest stars are blue. And for a star, the only thing that defines the temperature of a star is its mass. Blue stars are stars that have at least 3 times the mass of the Sun and up. Whether a star has 10 times the mass of the Sun or 150 solar masses, it's going to appear blue to our eyes.
An example of a blue star is the familiar Rigel, the brightest star in the constellation Orion and the 6th brightest star in the sky. Astronomers calculate that Rigel is approximately 700 and 900 light-years away, and yet it appears almost as bright as a star like Sirius which is only 8.3 light-years away. The temperature of Rigel is approximately 11,000 Kelvin; it's this high temperature that accounts for Rigel's color. Rigel puts out about 40,000 times the energy of the Sun.

How do scientist use the electromagnet spectrum to determine the temperature of a star?
Anything with heat emits electromagnetic radiation, even if it is only in the infrared (IR) wavelengths. As matter gets hotter, it tends to change color. For example, if you've ever seen glowing metal at a steel mill or in a blacksmith shop (like on a movie) you notice hot metal glows red, hotter metal glows yellow, and even hotter metal glows white. If you apply this concept to stars, you can start to see that by measuring the color, you are also measuring the temperature - how? because a star at a certain temperature glows a certain color. Reds are the "cooler" stars (still very hot) and blues are the hottest stars - at least when we are talking visible spectrum.
What colors are binary stars?
Binary stars can be any color that stars can be. There's no need for the two stars in a binary to be the same color.
Why do stars with smaller masses burn longer than stars with larger masses?
Stars with larger masses have stronger gravity; this results in more pressure; which in turn makes the star hotter. As a result of the higher temperature, they will shine brighter, and burn their fuel much faster.
What is the relationship between a flames color and its temperature?
The hotter the temperature the darker the colour and the colder the temperature the brighter/more blue the colour so if it is going to be hot some where when you look on a weather radar then it will be darker in that are and if it is colder it will be brighter/more blue.
Who is hotter ichigo or toshiro?
I'm not sure who is hotter but in a fight my money is on Ichigo
Smaller stars tend to be?
Hotter.
Does the color of the star depends on its size?
Yes, the color of a star is determined by its temperature, with hotter stars appearing blue/white and cooler stars appearing red. Generally, larger stars tend to be hotter and appear bluer, while smaller stars are cooler and appear redder.
Why are cooler stars red and hotter stars blue?
It may seem counter intuitive, but temperature defines the color of an object and the hotter an object is, the more its color will tend towards the left side of the color spectrum. As someone else said before on this site, thinking about heating a metal rod puts things in perspective. As you heat the rod, it glows red and than bluer in color as it heats up. Also, think about the hottest area of a flame--the flame is hotter at the point where it is blue in color rather than red.
What are the mostheat of color in stars?
The hottest stars still undergoing fusion tend to be blue in colour. These stars rarely get above 50,000 K. Even hotter stars are white dwarfs. They appear white with maybe a blueish tone. They can be as hot as 250,000K.
What information does the color of a star provide?
The color of a star provides information about its temperature. Blue stars are hotter than yellow stars, which are hotter than red stars. This color-temperature relationship helps astronomers understand the life cycle and characteristics of stars.
How are temperature and color in stars linked?
The hotter they are, the bluer they are, the cooler they are, the redder they are.
What color are the hottest and the coldest stars?
The hottest stars are blue and the coldest stars are red because blue is the color made by hotter burning things and red is the colest burning color.
What color stars are the hottest and the coldest?
The hottest stars are blue and the coldest stars are red because blue is the color made by hotter burning things and red is the colest burning color.
The color of a star is a clue to its what?
The color of a star is a clue to its temperature. Hotter stars tend to be blue or white, while cooler stars appear red. This is because the wavelength of light emitted by a star changes with temperature, leading to different colors.
What information can be derived from the color of a star?
The color of a star can provide information about its temperature and age. Hotter stars tend to appear blue while cooler stars appear redder. By studying the color of a star, astronomers can determine its surface temperature and stage in its life cycle.
Are all bright stars the same temperature?
No, bright stars can have different temperatures. The color of a star typically indicates its temperature, with blue stars being hotter than red stars. Brightness is influenced by both temperature and size; a larger, cooler star could appear brighter than a hotter, smaller star.
Are planets or stars hotter?
stars are hotter
