This completely depends on the speed of the observed galaxy, the speed of the galaxy the observer resides in, and in which direction both galaxies are moving in relation to each other.
There are too many variables to provide an answer at this time.
It's because they are so far away. Even the closest one is 9000 times as far as Neptune. Going another 9,000 times further does not go as far as the centre of the galaxy.
The black hole at the center of our galaxy, the Milky Way, is about 26,000 light-years away from Earth. It is known as Sagittarius A* and has a mass equivalent to about 4 million times that of our sun.
Because they are so far away, they seem tiny, because of perspective.
True
No galaxy is 2.9 million miles away - they are much, much farther. Even the closest star in our own galaxy is much farther away than that.

Mars, like Earth, is in the Milky Way galaxy. The next nearest galaxy is the Andromeda galaxy, which is about 14,696,575,000,000,000,000 miles away.
So far we haven't been able to get anything to another star, a galaxy is a million times farther away.
Five minutes away!
The farther away another galaxy is from our solar system the less effect that the gravitational pull will have on that galaxy.Thus allowing the other galaxy to travel at a faster rate.
Hubble's Law states that (more or less) the distance to a galaxy is a constant multiple of the distance to that galaxy. For example, if one galaxy is moving away from us at three times the speed of another galaxy, then that means it is also three times as far away. The Law indicates that the Universe is expanding and had a beginning. Before Hubble's Law, many astronomers thought that the Universe did not have a beginning (it always existed).
Somewhere is another Galaxy far far away
The black hole at the center of our galaxy, the Milky Way, is about 26,000 light-years away from Earth. It is known as Sagittarius A* and has a mass equivalent to about 4 million times that of our sun.
Because they are so far away, they seem tiny, because of perspective.
This is not possible, they are much too far away.
There is no such galaxy, the nearest galaxy is over 2 million light-years away.
According to Nasa, The Milky Way (Our galaxy) will crash into Andremoda and our galaxy will slowly wash away.
