Oh, boy. More 'earthlike' planets in the 'habitable zone'. Tell me, someone - do we have any way to detect if these exoplanets have sufficient background radiation to fry human gonads like ping-pong balls in a cyclotron?

The expected distance from his start point was a lot more than twelve parsecs, due perhaps to an asteroid field, nebula, or some such. But Han found a way through the obstacle, cutting the distance to 12 parsecs?
If Disney keeps sneaking formerly canon stuff from the expanded universe into current canon, it'll be passing closer to a black hole than any other ships making the run. A.C. Crispin describes it in her Solo trilogy. It's also the same run during which he dumps Jabba's the cargo for which Jabba places the price on his head.

We'll have to wait until we can send gonads and a cyclotron there before we can know for sure.

No, but it does mean they'll know how to make a good beer.

Some of the planets do not rotate around their own axis around their sun.
So you either live in hot light or cold darkness.
The border zones there are very expensive there these days!

Black hole is sexy and it makes physics sense that you'd need more power and maneuverability to slingshot closely round a black hole, let's go with that, Disney!
I hope they make that one a spectacular adventure without losing much of the cinematic quality of R1

It would have to be one enormous black hole for it to be possible to cut parsecs off of the slingshot distance around it. You would barely feel the gravity of any stellar massed black hole from even 1 parsecs away. Also, wouldn't relativistic effects mean the trip would actually take longer if the trajectory cuts too close to the event horizon?

I'll try to do the math for a supermassive black hole and get back to you... He'll have to do hyperspace as well to travel parsecs, so it's not clear what the physics of that would be though...

Even if not inhabited by anything, there's a good chance that one would be very suitable for terraforming, though I'm very unlikely to live long enough to even see a probe (or probe cloud) get launched for the mission of investigating something 40 light years away more closely.
I've been waiting most of my life just for a moon colony or permanent space station habitat.
