Can the human race live somewhere else in the mikyway?
Yes it IS possible.There are over 200 billion stars to choose from. There must be a suitable planet orbiting one of those stars.The BIG problem is getting to them.Our nearest star system, Alpha Centauri is 4.2 light years away. (Unfortunately, to date no planets have been found around them).Our fastest craft, Voyager 2 is travelling at about 35,000 mph. If it was to make it to Alpha Centauri, it would take ..... about 80,500 years!!!

Are stars that appear the brightest are also the closest?
No. The sun is very close to us so it seems very bright. There are a lot of stars that are much brighter than it, but are very far away. It is the same with the other stars. There are some very bright ones that are very far away and some dimmer ones that are closer to us. After the sun, the next brightest star is Proxima Centauri. The brightest star in the night sky that we see is Sirius, which is close, but much further away than Proxima Centauri.
