Would a light source moving away from Earth appear blue shifted or red shifted?

A red shift indicates an object that is moving away from the observer, and a blue shift indicates an object that is moving toward the observer. Both of these are called Doppler shifts.

If a star is moving toward Earth it is?
blue shifted
How can astronomers tell if a star is approaching or receding from earth?
The relative motion between the observer and wave source causes an apparent change in frequency which is known as Doppler Effect. On combination with identification of spectra, it can also be used to find if the start is moving away or towards the earth, When there is shift in lines of spectra towards the red end of visible spectrum the star is said to be travelling away from the earth.
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).
Why do different stars appear during different seasons?
Because earth is moving
How do people know when a star is moving toward or away from the earth?
blue shifted
If a star is moving toward Earth it is?
blue shifted
If a star is moving toward earth is it?
blue shifted
Is a star is moving toward earth it is?
blue shifted
Does the medium of space make distance stars appear to be more red shifted only because they are farther away?
Distant stars appear red shifted because they are travelling away from Earth. It just happens that more distant stars are moving faster, so there is a greater red-shift the further a star is from the Earth.
If a galaxy is moving towards the earth what direction does its spectrum move?
It will be blue shifted
Is an object that is not moving relative to Earth a blue shift?
No, an object not moving relative to Earth is not a blue shifted object. With no relative motion, an object will not be subject to Doppler effect and will not red or blue shift. For an object to be blue shifted, the distance between the object and Earth must be decreasing. The object must be closing on Earth or vice versa.
All of the constellations appear to be moving because what is moving?
Because of Earth's rotation.

Why do stars appear to move across the sky from season to season?
Because Earth is moving so we are the ones moving.
Why do different stars appear during different seasons?
Because earth is moving
What causes the stars in the sky to appear to be moving?
The Earth's rotation. The relation between the Earth (or a person on the Earth) and the position of the stars makes it appear that the stars are in a different position as the night progresses.
