Using the Doppler effect astronomers can determine a stars what?
How close and far something is from you.
Why does Rigel not look as bright as Sirius?
Because Rigel is much farther away. Rigel is 770 light-years away, and Sirius is only 8.6 light-years away.
How far is rigel in light years?
Rigel is approx 860 ly away.
How many light years is rigel?
Rigel is 860 +/- 80 ly away.
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.
Why is the Andromeda galaxy moving toward earth?
Sorry, Andromeda and earth are moving away from each other, not towards each other.
Is Uranus farther away from earth than the star Rigel?
No. Rigel is much farther away than Uranus. Uranus is in our Solar System.
In which direction are nearly all galaxies moving relative to earth?
they are moving in all directions away, toward, sideways relative to EarthNearly all galaxies are moving away from the Earth. This is because the universe is expanding.
How many miles does Rigel is away from Earth?
Distances between stars are not measured in miles: that is like measuring the distance from the Earth to the Sun in thousandths of an inch! However, since you asked, Rigel is approx 5 quadrillion miles away.
Is the Black Eye galaxy moving toward away or neither from Earth?
The Black Eye Galaxy [See Link] has a redshift of 0.001361, so it is moving away from us. Currently at 24 million light years from 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
Are most volcanoes on land caused by the Earth's plates moving away from each other or moving toward each other?
all volcanoes are caused by the earths plates moving toward each other and that is called convergent boundaries.
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.
What distance is rigel have?
Rigel is 260 +/-20 parsecs away.
Why does Rigel not look as bright as Sirius?
Because Rigel is much farther away. Rigel is 770 light-years away, and Sirius is only 8.6 light-years away.
Objects that are moving away from us give off what light and objects that aremoving toward us gives what light?
Due to the doppler effect, objects moving toward us will be slightly more red than what they actually are, and objects moving away will be slightly more blue. Think of it like a siren coming toward you and moving away from you. If it is moving toward you, it will be slightly higher than what it really sounds like. If it is moving away it will have a slightly lower pitch.
