I'm trying to figure out how to outfit a ship to jump to Charybdis III, and my current ship is a hair too underpowered to reach the planet. While I'm trying to improve my astrodynamics score, which should get me jumping far enough to reach it - I feel like knowing what's the 'longest' I need to jump would be helping me upgrade/outfit my 'perfect' ship.

So what's the longest distance between 2 planets?

  • Two planets, or two stars? I don't think Lightyears come into play when jumping between planets in a single system

  • Oh, I generally tend to think of it as planets, but technically I'd guess stars Commented Oct 7, 2023 at 5:04
  • @JourneymanGeek I think technically they would be systems, as you can't actually jump to the star itself :)

According to this site the max distance between two stars in 28 LYs, so a GravDrive of 28 LY or better should do.

In trying to locate this 28 LY jump, I actually found several jumps that were 28.XX LY's away. The longest jump was from Wolf to Alpha Andraste which is 28.518 LY in total, so I'm not sure if a 28 LY GravDrive will cut it, and you might need a 29 LY GravDrive. All of my current ships have 30 LY GravDrives, but I will try and find one with a 28 LY GravDrive to test.
