This all presumes a burn rate of 11 (because thats what my fleet does & measuring this with sustained burn is hard).
If you go to one jump point in Galatia and set a course for the other jump point, in-system it's a 2 day trip, out of system its about a .2 day trip. The trip from Galatia to Corvus in hyperspace is a 1 day trip so by sublight that would take 10 days, which is the equivalent of going from Galatia to Westernesse in hyperspace so if the game had no hyperspace & was all 1 map at its current scale it would take a solid minute & a half of burning through the deep black of deadspace, or at a sustained burn of 20 about 45 seconds, to get from the star of Galatia to the star of Corvus
But, the core worlds are notably very close together. By that measurement, the time to burn from Galatia to the nearest procgen system the hard way would be 80 days, which means if there were no hyperspace & the game remained at its current scale, crossing from the core to the outer rim would take 12 uninterrupted minutes of burning through the darkness of space, left alone with your thoughts and hoping to god you brought enough supplies
