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.
Away, at around 18 km/s.
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.
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.
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.

They craped in the toilet and Looked up in the sky and said sh!t Sirius is moving away from earth.
A freaking telescope

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.
they look at the sky and say hi to barney

that an object is moving away from an observer. This red shift occurs because the wavelength of light is stretched as the object moves farther away, causing it to appear more red. This effect is commonly seen in astronomy with galaxies moving away from us due to the expansion of the universe.
