In the beginning of The Rise of Skywalker we can see the Millennium Falcon do something that they call lightspeed skipping.

How does that work and what makes it different from regular lightspeed travel?

    "what makes it different from regular lightspeed travel?" Poor writing, and ignoring the existing and Disney approved/confirmed/reinforced canon that Hyperspace travel is disrupted by gravity wells (so you can't jump after until you leave orbit of a planet - which is also the reason that the [spoiler] ships can't leave Exogal without taking off first...) – Chronocidal Jan 8 at 13:25
  • @Chronocidal FWIW established canon is that it is possible to hyperspace jump in a gravitational well, it's just that it is strongly advised against. – TheLethalCarrot Jan 8 at 14:55

    @TheLethalCarrot Interdictor-class Star Destroyers used gravity wells to not only stop ships jumping to hyperspace, but also to pull ships in hyperspace out into normal space (Rebels S2E09 "Shadow Strike" and S3E21-22 "Zero Hour") - the closest previous examples are from low-orbit (which is indeed described as being extremely hazardous and uncontrollable). Poe, on the other hand, combines this with the "crazy" move of dropping out of hyperspace under the same circumstances (first done by Han in TFA after exposition of how dangerous and almost impossible that is) and the TIE fighters follow – Chronocidal Jan 8 at 15:52

    Traveling through hyperspace is like dusting crops after all. – Essen Jan 8 at 20:09
  • Usually lightspeed skipping means regularly spending time in a ship travelling near lightspeed in normalspace in order to take advantage of relativistic effects to "skip" through normal time. – SaintWacko Jan 8 at 21:29

We have very little information on lightspeed skipping or hyperspace-skipping. It appears to have been invented for The Rise of Skywalker. Obviously in the film we only get to know that it's possible but dangerous and see it happen. The Visual Dictionary goes into a little bit more detail spread over several sections though:

A daring run of "hyperspace skipping" - a new variant of old smuggle tactics designed to evade Imperial pursuit - has exhausted its compressor systems and both sub-alternators.

Poe beats a hasty retreat from Sinta Glacier by hyperspace-skipping the Falcon through a quick succession of deep space obstacles, including the Megafauna Chasm of the Typhonic Nebula, the Mirror-Spires of Ivexia, and the Crystal Chaos of Cardovyte.

Poe has perfected hyperspace-skipping, a dangerous series of precalculated lightspeed hops meant to throw off First Order attempts at tracking.

From the above we can see that it is essentially a series of short, normal lightspeed jumps combined together down a precalculated route.

  • I don't think it was called this in the film, but was this in any way related to the trick in the climactic scene in Solo? You know, the "Kessler Run in 12 parsecs" retcon? – Darrel Hoffman Jan 9 at 14:27
  • @DarrelHoffman It's been a while since I watch it but they don't do hops in that do they? And it certainty doesn't seem pre-calculated. – TheLethalCarrot Jan 10 at 9:20
  • It was just one jump, I think, but it was within a very strong gravity well (near a black hole), which is the key similarity. Normal, safe hyperspace jumps are generally done away from any strong gravity well, but both the Kessler maneuver and the "skipping" maneuver were done near gravitational wells (a black hole for the former, and a series of planets for the latter). – Darrel Hoffman Jan 10 at 14:15

    @DarrelHoffman Then I guess in Solo it was just a dangerous normal jump. – TheLethalCarrot Jan 10 at 14:16

    It sure didn't look precalculated to me – yoniLavi Jan 13 at 19:37
