I have heard scientists say that our solar system is in the galactic Goldilocks zone. If I remember right, it's like what we have now in our system - a cold zone, a hot zone, and a habitable zone.
Our system is not in a fixed location - it's orbiting the galactic core. I wonder if our orbit will bring us closer to an inhabited system in the future. Of course, this would be a long time into the future.
