The outer edges of the cloud seem to be at ~100K AU [0], while the α Centauri system is ~268K AU from us [1]. NASA also gives the same number [2] for the distance to the edge of the cloud. So, it looks like the Cloud extends almost halfway to α Centauri, but not that it's "closer to α Centauri than us").

- alistairSH 5y agoHuh, the first paragraph of that same wikipedia says the cloud extends to 2000 AU. Either way, whenever I try to think about these things, I feel mild anxiety. Why am I here? What's the point of all this? I'M SO TINY! Aaaahhhhhhhhh! I probably need to lay off the sci-fi novels for a while.
