Is the rigel star moving toward or away from the earth?
Away, at around 18 km/s.
How can a spectroscope be use to find out if a star is moving?
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.
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.
How do astronomers determine if a star is moving towards or away from us?
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.
How do people know when a star is moving toward or away from the earth?
blue shifted

How did astronomers discover that the star Sirius was moving away from earth?
They craped in the toilet and Looked up in the sky and said sh!t Sirius is moving away from earth.
What did the astronomers use to discover that the star Sirius was moving away from Earth?
A freaking telescope

How do you determine whether a star is moving closer or farther away from us?
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.
How do scientist determine whether a star is moving toward or away from earth?
they look at the sky and say hi to barney

A Doppler red shift indicates?
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.
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.
How can astronomers determine whether a star is moving towards or away from earth?
Astronomers determine whether a star is moving toward or away from the Earth via the Doppler effect. Imagine a motorcycle moving past you. As it drives towards you, it has a higher frequency, and a lower frequency when it drives away. The same thing happens with light. As an object moves towards us, its light has a higher frequency and lower wavelength - this is called blueshift. As an object moves away from us, its light has a lower frequency and higher wavelength - this is called redshift.
