Question:
When was the sun formed?

What's the closest star besides the sun to the earth


Replies:
The sun was formed about 5 billion years ago (around the same time the earth formed). The closest star besides the sun to the earth is Proxima Centauri which is part of three stars that orbit about one another, so one of the others will be the closest star at some point in the future. The distance to these is about 4 light-years.
