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

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.

∙ 14y agoI 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.

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.

∙ 13y agoStellar temperature can be measured by analysing the spectrum of light that stars emit; shorter wavelengths correspond to higher temperatures.

What do astronomers do to-learn about properties of stars?
The almighty spectroscope, it breaks the holy light coming from the star into different colors so we can actually examine it's properties without going blind or incinerating ourselves.
Name and describe the phase change that occurs when dry ice is placed in an opened container at room temperature?
Dry ice (solid CO2) at room temperature changes from a solid to a gas without going through the liquid phase. This is called sublimation.
When temperature is decreased on a gas and it becomes a solid without a liquid stage this is called?
Deposition. The reverse process (going from a solid directly to a gas) is called sublimation.
Why is it important to measure accurately?
it is important to measure mass accuratley because if you dont everything is going to fail.
How do you know what the water temperature is going to be tomorrow?
You do not, especially when the location is not specified.
Is there a job related to an astronaut?
An astrologist maybe. Some astronomers study space without going to space lol
How do you take care thermometer?
the thermometer is an object that we going to measure of an temperature of one person.
Can you measure distance without a tape measure?
well, a stopwatch and a speedometer will do. Get the speed and time of going through this distance, and multiply by them, you will get the number.

Why astronomers don't think the world is going to end in 2012?
Because there is no evidence to suggest that it will
Why entropy and temperature has inverse relation explain?
entropy is the measure of disorder in a system having direct relation with heat because it tells about the availability of heat more heat require to do useful work more is the entropy and having inverse relation with temperature because temperature tells the measure of agitation in an atoms of system that entropy is going to be measured.
How did the Chinese kites impact their society?
kites have had a significant impact on the society and environment. Kites can measure the temperature for the weather which leads to people knowing what the weather is going to be for the day.
How have past astronomers learned about Neptune?
Jasleen Kaur Dhunna sucks!. that's all im going to say!
Astronomers are interested in solar neutrinos because neutrinos carry with them information about?
The nuclear reactions going on in the heart of the Sun.

How do you know if your air conditioner in overcharged?
With refrigerant gauges we read the pressures and measure the temperatures, without that we look at the amp draw and what the air temps are going in and out,
How is kinetic related to temperature?
They are not related. Kinetic Energy has to do with the speed or how fast something is going. Temperature has to do with how hot or cold something is. Maybe you are thinking of THERMAL ENERGY. That has to do with heat.When the temperature increase, that substances will tend to vibrate and then at a certain high temperature will start to move;that is why we say it gain energy.Temperature is a measure of the kinetic energy of the particles of a substance.
