The distance to the Andromeda Galaxy is estimated at 2.5 million light-years. The distinction between "near side" and "far side" is irrelevant, since the diameter of the Andromeda Galaxy is probably less than the error in the distance estimation.
the light year
The distance between stars is a couple of order of magnitudes higher than the distance between planets.To put this into perspective, the distance between earth and the sun is 8 light-minutes and the distance between other planets doesn't go further than a few light-hours. On the other hand, the distance between our sun and the nearest star (alpha centauri) is 4.4 light-years. This means that this distance is about 38544 larger than the distance between planets.Beyond that, the distance between stars can be extremely high: a star on the other side of our galaxy will be about 100000 light-years away from us. The distance will keep rising as we move on to different galaxies, then different galaxy clusters, the super clusters and then, finally, the width of the universe.
We can tell the distance is decreasing because the light from Andromeda is blue shifted. That galaxy is closing in on us (or vice versa) 500,000 km (300,000 miles) per hour.
The farther away the galaxy is from ours the faster it moves from our galaxy.
v = H0D Where v is the velocity at which a galaxy moves away from us, and D is its distance. With H0 being the constant of proportionality (the Hubble constant) between the distance D to a galaxy and its velocity v.
It means that, the farther away a galaxy is from us, the faster it moves away from us.
First of all . . . it's not the speed of light. It's the relationship between the galaxy's distanceand the speed with which it's receding from us.The farther from us a galaxy is, the faster it appears to be receding.The proportionality constant is named after the astronomer who measured it. It's the Hubble Constant.
Relationship between distance of galaxy and its speed is that galaxies are moving away from the Earth at velocities proportional to their distance. In other words, the further they are the faster they are moving away from us.
well it is 1478904523564 kilometres dollop quite a long way !!

He discovered that the farther away a galaxy was, the faster it was moving away from Earth.
The distance is zero. Along with us, the moon is in the Milky Way Galaxy.
The sun is one of an estimated 400 billion stars in our galaxy.
