Do red stars have higher surface temperatures than blue stars?
No. Red stars have the lowest surface temperatures while blue stars have the highest.
Which stars have the highest surface temperatures red star or blue stars?
Blue stars have the highest surface temperature, at over 7,500 Kelvin. The surface temperature of red stars is less than 5,000 Kelvin.
How do scientist determine the surface temperature of the stars?
brightness
How do scientists determine the chemical makeup of the stars?
Different chemicals emit and absorb light at various wavelengths. Astronomers can look at the wavelength of light coming from stars and determine which chemicals must be present.
Using the Doppler effect astronomers can determine a stars what?
How close and far something is from you.
Do red stars have higher surface temperatures than blue stars?
No. Red stars have the lowest surface temperatures while blue stars have the highest.
What is the color of the stars that have the lowest surface temperature is?
Red stars have the lowest surface temperatures.
What are two kinds of information astronomers can collect from stars by using spectrographs?
compositions and temperatures
What is another name for a plot of surface temperatures of stars against their absolute magnitude?
This type of diagram is often called a Hertzprung-Russell diagram after two astronomers.
What are the stars in the main sequence?
The smallest stars in the main sequence are the stars with cooler surface temperatures.
Why is the HR diagram useful to astronomers?
It can be used to determine a Stars lifetime, its different stages.
How astronomers measure stellar temperatures?
Stellar temperature can be measured by analysing the spectrum of light that stars emit; shorter wavelengths correspond to higher temperatures.
What are the surface temperatures of the stars in the constellation Virgo?
because it is awesome

Which stars have the highest surface temperatures red star or blue stars?
Blue stars have the highest surface temperature, at over 7,500 Kelvin. The surface temperature of red stars is less than 5,000 Kelvin.
How do astronomers determine the precession of the earth?
By finding a constant, continuous change in the coordinates of stars every year.
