How far is the furthest star?
The furthest galaxy is about 14 billion light years away.
The furthest star in our own galaxy is something like 70,000 light years away.
The milky way is over 1000,000 light years across - and or Solar System is located on one of the outer spiral arms. Therefore directly across to the other side of the galaxy from us, is the furthest star in our galaxy.
The furthest star in the universe, is going to be about 13 -> 14 billion light years away and getting further away.
The visible universe goes out about 15 billion light years, so that would be the distance to the furthest visible star. There are surely stars beyond that but because we cannot see them we cannot know.
