the stars don't move the earth rotates and that's why we think we see the stars move

What phenomenon accounts for the blue shift of a star moving towards Earth?
The Doppler effect
How are the red star and blue star alike?
They can be the same sort of star, it's just that the one moving quickly away from us LOOKS red BECAUSE it is moving away, while the one moving quickly toward us appears blue because it is moving toward us. This is caused by a physical phenomenon called a Doppler Shift. Edit: That's a special case, but I don't think that's what the question is about. In fact I'm not sure what the question is about exactly. It's one or those annoyingly vague questions.
What type of star is Zeta Herculis?
Zeta Herculis is a binary star system in the constellation Hercules.It has a class of G0V which means it is similar to our Sun but is moving away from the main sequence.It's companion star is a class K0V
What can electromagnetic spectrum tell us about a star?
Information that you can find about the star by looking at its spectra is its luminosity, surface temperature, its type(common/rare), color, how/if a star is moving, the density, the size, and future of the star. 2. And looking for spectral lines informs as to what elements are present.
What can astronomers learn about the stars motion based on wavelength shifts?
They can determine how fast the star is moving toward or away from us. The chemical spectral signature is used to determine the Doppler shift of the visible light reaching us. This is then used to calculate how fast we and the star in question are moving toward or away from each other.
What is moving star?
You mean "what is moving the stars?" Well, I answer you with this: nothing. The stars are not moving. No stars move. The closest you will ever get to see a star moving is when Justin Beiber moves from LA to Miami.
Is a star shifting to the red spectrum moving closer or farther from us?
If it were moving it would be moving away from our perspective. However, just because a star is shifting spectrum does not mean that it is moving; it could be entering the next stage of the star life cycle.
Spectrographs help astronomers determine a star's what?
The star's chemical composition; the star's rotation; pulsations of the star; planets or other invisible objects moving around the star; how quickly the star is moving towards us or away from us.
Where did the term shooting star come from?
From the fact that it looks like a quickly-moving star.
Why star is moving?
You grammer are terrible. And no, the stars are not moving. The Earth is rotating on its axis (spinning), so they appear to be moving around us. They are stationary (not moving).
What is moving towards the star vega?
Our solar system
If a star is moving toward earth is it?
blue shifted
Is a star is moving toward earth it is?
blue shifted
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.
Which star does not appear to move and why?
The north star doesn't appear to move because it is at the tip of the axis of the Earth so we view it as not moving. All stars move because they are full of energy and ready to zoom. The north star is also moving, but since the Earth is spinning so quickly it seems to not be moving. Hope this helps :).
Why is the Jonas Brothers moving?
Why ARE the Jonas Brothers moving? They're probably just moving because not every star can live in California & Nickk was born in Dallas.
How fast is the light from the star moving towards the earth?
47km/h
