The Hubble Constant ... relating distance to speed of expansion ... is currently estimated
as 71 kilometers per second per megaparsec. (Plus or minus 10 percent. The number
has been hotly debated and actively researched for the past 80 years.)
1 parsec = 3.26 light years.
10 billion LY = 3,067.5 million parsecs (rounded)
Speed of recession = (3,067.5 million parsecs) x (71 kilometers per second per megaparsec) =
217,800 kilometers per second (rounded)
= 72.5 percent of the speed of light (rounded)

How fast is a galaxy 3400 billion light years from earth moving away from us?
A galaxy that is 3,400 billion light-years away from Earth is likely moving away from us at a significant speed due to the expansion of the universe. According to Hubble's Law, the recessional velocity of a galaxy is proportional to its distance from us. At such extreme distances, the galaxy could be receding at a speed approaching or even exceeding the speed of light due to the expansion of space itself. However, since nothing can locally exceed the speed of light, this recession is a result of the metric expansion of space rather than the galaxy moving through space.
When you see a galaxy 8 billion light-years away you are looking how many years into the past?
When you see a galaxy that is 8 billion light years away, the light that's dribbling into your eye left that galaxy 8 billion years ago, and has been traveling toward you ever since then. If you just happen to see the galaxy explode or turn blue while you're watching it, you'll know that it actually exploded or turned blue 8 billion years ago. Similarly, if the galaxy explodes or turns green tonight, you won't know about that for another 8 billion years from tonight.
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
If a galaxy is moving towards the earth what direction does its spectrum move?
If a galaxy is moving towards the Earth, its spectrum will be blueshifted. This means that the wavelengths of its emitted light are compressed, resulting in a shift towards the blue end of the spectrum.

How far is the Andromeda Galaxy from Earth in Light Years?
The Andromeda Galaxy is approximately 2.537 million light-years away from Earth. It is the nearest spiral galaxy to the Milky Way and is on a collision course with our galaxy, expected to merge in about 4.5 billion years.
How long would it take light to travel from the furthest observable point in the universe to earth?
45 billion light years, if you define the size of the visible universe as the present physical distance (in terms of the “co-moving coordinates” which are stationary with respect to the cosmic microwave background) to the farthest things we can see.
What is the furthest star in the galaxy that has been viewed from earth and how many light years away is the star?
