alt Hacker NewsAnother comparison: if you count the "solar system" as ending at Neptune's orbit (obviously it extends much further, but just for the sake of comparison), then you could fit ~4465 "solar systems" in between our sun and the closest star, Proxima Centauri.
As I understand it, there is no consensus on the size of our solar system. We can measure the orbits of the planets, but it is much harder to measure where the Kuiper Belt or the Oort cloud ends. Estimates on both of those vary greatly.
