How is the solar system located in an outer edge of the disc shaped milky way galaxy?
Question:
Answer:
We are not really on the outer edge of the Milky Way. We are on the outer edge of one of the spiral arms, but six thousand lightyears further out we come to another spiral arm. Of course, that doesn't make us close to the center, either. Not by about 28,000 ly!
How? It just is -- there's no "how."
We're here because that's where our sun formed. That's it.
But we're not really on an "outer edge," more like 3/4ths of the way to the edge from the center. We're in a relatively calm part of the galaxy -- which makes sense, because it takes a long time for life to evolve, and had we been in a more active part of the galaxy, catastrophic events would be more likely and there would be more of a chance of our solar system or planet being disrupted before life had a chance to take hold.
When the galaxy formed, the solar system formed there.
When you ask "how" do you mean "how could our incredibly important planet and star only be in the 'suburbs' of our galaxy, when its obvious we should be the centre of all things"?
