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).
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.
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.
From the fact that it looks like a quickly-moving star.
A spectroscope can determine if a star is moving by analyzing the light spectrum emitted by the star. When a star moves away from Earth, its light is redshifted, meaning the wavelengths are stretched and appear longer. Conversely, if the star is moving towards Earth, its light is blueshifted, with shorter wavelengths. By measuring these shifts in the spectral lines, astronomers can quantify the star's velocity relative to Earth.
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.

To determine whether a star is moving closer or farther away, astronomers often use the Doppler effect, which causes the light from a moving star to shift in wavelength. If the star is moving closer, its light appears blue-shifted, meaning the wavelengths are compressed. Conversely, if the star is moving away, its light appears red-shifted, with the wavelengths stretched. By analyzing the spectrum of the star's light, astronomers can measure this shift and determine its motion relative to Earth.

Astronomers use the Doppler effect to determine if a star is moving towards or away from us. By observing the shift in the star's spectral lines towards the blue end of the spectrum (blueshift) or the red end of the spectrum (redshift), astronomers can infer the star's motion relative to Earth. Blueshift indicates the star is moving towards us, while redshift indicates it is moving away from us.
To find the speed of a star using Doppler shift, you can measure the change in the wavelength of light emitted by the star. If the light is redshifted, the star is moving away from us; if it is blueshifted, the star is moving towards us. By analyzing the amount of shift, you can determine the star's speed relative to the observer.
When a star is moving toward an observer, they would observe a blue shift in the light emitted by the star. This shift occurs because the wavelengths of the light are compressed as the star approaches, resulting in shorter wavelengths that correspond to the blue end of the spectrum. The blue shift indicates that the star is moving closer to the observer, which can be measured to determine its velocity relative to Earth.
Why ARE the Jonas Brothers moving? They're probably just moving because not every star can live in California & Nickk was born in Dallas.
