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.
When a star moves toward the earth light that it gives off is what color?
Well I think you mean a comet, because stars are not moving to the earth, and the tail of the comet would be red or blue depends on which side your looking at it.
What is a star call when it is moving away from the earth?
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
If a star is moving toward earth is it?
blue shifted
Is a star is moving toward earth it is?
blue shifted
Is the rigel star moving toward or away from the earth?
Away, at around 18 km/s.
How can astronomers determine whether a star is moving toward or a way from earth?
They can do so by examining the light from the star. Doppler shift can indicate this
How do scientist determine whether a star is moving toward or away from earth?
they look at the sky and say hi to barney

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.
If the earth rotates from the west to the east why do the sun and Star move from the east towards the west?
They are not actually, moving, they just appear to be moving because we are. Consider that if you are on a train moving forward, objects that you pass by appear to move toward the read of the train.
Why can't the earth be seen moving toward you when you jump up in the air?
you can't see it moving because your moving with it
Why is the Andromeda galaxy moving toward earth?
Sorry, Andromeda and earth are moving away from each other, not towards each other.
Which neutron star emits radiation toward the earth?
A pulsar.
When a star moves toward the earth light that it gives off is what color?
Well I think you mean a comet, because stars are not moving to the earth, and the tail of the comet would be red or blue depends on which side your looking at it.
