A star moving away from the earth is still called a star, but the color of the light that we see will be "redder" than it actually is. This is called redshift, and a link can be found below for more information.

A Doppler red shift indicates?
a star is moving AWAY FROM EARTH
Is the rigel star moving toward or away from the earth?
Away, at around 18 km/s.
Does the velocity of a star toward or away from earth determine measuring the shift of its spectral lines?
Yes. If the star is moving away from the Earth, its spectral lines will shift towards the red end of the spectrum. If it is moving towards the Earth, its spectral lines will shift towards the violet end of the spectrum. This is due to Doppler effect.
How do people know when a star is moving toward or away from the earth?
blue shifted
Stars moving away from the earth show a red shift Why?
The star is moving away from us. Therefore, the Doppler effect must be considered. The Doppler effect is waves (in this case light) will be compressed in front of a moving object and stretched behind the object. This stretching creates a long wavelength. Red light has a long wavelength (the longest of visible light), so we call this stretching red shift.

How did astronomers discover that the star Sirius was moving away from earth?
They craped in the toilet and Looked up in the sky and said sh!t Sirius is moving away from earth.
What did the astronomers use to discover that the star Sirius was moving away from Earth?
A freaking telescope

How do scientist determine whether a star is moving toward or away from earth?
they look at the sky and say hi to barney

If a star is moving toward earth is it?
blue shifted
Is a star is moving toward earth it is?
blue shifted
Which has a higher frequency a star moving away from earth or towards earth?
I would think that current evidence suggests that the stars moving away from earth, some of them in far distant galaxies moving at unimaginably high speeds, are going much faster than stars moving toward us. The entire Andromeda galaxy is moving toward us and will collide with us in roughly 5 billion years, and it is not moving anywhere near as fast as the distant retreating galaxies.

Star 3.2 million miles away?
There is no star that is just 3.2 million miles from the earth. The nearest star to the earth is the sun which is about 93 millions away.
