How do the astronomers measure the temperature of the Sun without going there?

Answer 1

Color Scientists use spectrometers to create

the color patterns produced by suns light

Thus they can use spectrometer on earth with

some hot source to see what colors it can give

and thus the colors on sun can tell their temperature. This method is called Spectral Classification.

Answer 2

Astronomers measure the temperature of the Sun by analyzing its spectrum of electromagnetic radiation. They use instruments such as spectrographs to observe the wavelengths of light emitted by the Sun. By studying the intensity of different wavelengths, they can determine the temperature of the Sun's outer layers.

Answer 3

I don't know if they can measure the exact temperature, but it depends on the star's color.

If it is white or blue, they are extremely hot.

If it is yellow, like ours, it is medium temperature.

If it is red or orange, they are cooler stars, but still really hot.

Answer 4

Optical interferometry is the process to measure stellar radii. In essence, this is basic triangulation. Two telescopes are used which establishes the base of the triangle for calculation. The distances can then be determined and the radius of the star in question can be derived.

Answer 5

Scientists analyze the spectrum of a star to tell the temperature of stars.

By noting the wavelength at which the radiation emitted by the star is the most intense, we can calculate the star's temperature from Wien's displacement law.

Answer 6

Stellar temperature can be measured by analysing the spectrum of light that stars emit; shorter wavelengths correspond to higher temperatures.

Answer 7

By analysing it's spectrum. Blue is hot, red is cool.

See related question.

Answer 8

Depends on the color. Blue stars are the hottest, red stars are the coolest and the yellow stars are medium in temperature.

Answer 9

Astronomers can tell how hot a star is by the stars color. Different colors mean different elements that burn and frequencies which is the pressures in the stars.

Answer 10

A very long thermometer.
