What else can I help you with?
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.
What does the spectrum of a star determine?
The spectrum of a star provides information about its temperature, composition, and motion. By analyzing the spectrum, astronomers can determine the star's chemical makeup, age, and even whether it is moving toward or away from Earth.
How do you know if a star is moving toward us or away?
This is determined by measuring the "red shift" or "blue shift" of the star, or in other words, whether its perceived color on earth is shifted towards the red end of the spectrum or towards the blue end. This color shift effect is similar to the Doppler effect in that it is caused by the compression or rarefaction of waves by a moving object. So a star moving away from us would look slightly more red than usual because the light waves that reach us are drawn out due to the motion of the star. And conversely, a star moving towards us would look slightly more blue than usual, for the same reason.
Does a red shift indicates that objects are moving toward earth?
Red shift occurs when an object moves away from the observer. So as you are on Earth, it is when objects move away from Earth. (Blue shift as it moves closer.) A star's red shift could be due to losing energy to gravity.
Is a star is moving toward earth it is?
blue shifted
If a star is moving toward earth is it?
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.
