Our sun is believed to have formed in an open star cluster that would have long since dissipated. We do know of two stars, HD 162826 and HD 186302, that may be siblings of our sun and born to the same molecular cloud.
Cleveland. It used to be Sonnewitz.
It has made at least 20 orbits around the galaxy. So, probably not born anywhere near where it is now.
It seems weird talking about something cosmological and it’s only 20 twenty something. I mean it’s a number you can actual wrap your head around. Everything else in the universe is just mind-boggling.
You think the sun is stationary? It’s moving through the galaxy at a half billion mph.
You think the universe is stationary? It’s moving around the entire turtles head at 20 Billionsquillions chunkawumbas as per squegum

The universe has been expanding and speeding since started.
It’s definitely neat. That said, given that each orbit takes like 230 million years, it’s pretty easy to shift back into the realm of the mind boggling.
Right, but nebulae don't just spit stars out
Yes, but not relative to its original source.
I thought the sun was born in Ohio?
Yeah I can’t even fathom 1 million years. I suppose I can rationalise it as 500 times the amount of years since Jesus was crucified. But then to multiply that by 230 loses all meaning.
Yeah. It becomes pretty incomprehensible.
Another fun way to frame it: 230 million years ago, it’s the middle of the Triassic and dinosaurs are getting their start.
So, (very roughly) from around the time dinosaurs first appeared until now (with all the evolution and extinction in between that eventually led to today’s animals and humans, including all of human societal and technological development squeezed in at the very end) the solar system has orbited the galaxy one time.
20 somethings we can't understand. There's no way you or I truly get how far one orbit around the galaxy is, let alone 20.

It's also weird to think about how the constellations we see today were identified hundreds (or thousands?) of years ago and the stars' positions in the sky have changed little in that time. Yet one sun-orbital-period ago, it must have looked very different.

It was born roughly where is right now, I'd reckon.
