I must say that these rules are just what I was looking for. I'm about half way through and I need a bit of help, either I messed up an equation (most likely) or the transit times and distance for safe jump in the table are way off (less likely). I also apologize if this has already been answered before, but I don't have the time right now to check through all of the posts in this thread.

I rolled a K2V star which according to the table should have a 4.85 day travel time from either the zenith or nadir point to the habitable zone and the safe jump distance is 433,890,326 km.

But when I got to the section that covers the calculations for the Transit Distance and Transit Times I decided to run through that equation just to see.

According to the rules:

Transit Distance = √[(Distance A)^{2} + (Distance B)^{2}]

Where:

Distance A = .43 AU (according to page 86 of SO) * 150,000,000,000 m

Distance B = .7 (mass of the Primary) * .7 AU (base location for Orbit 2) * 150,000,000,000 m

Plugging these in I get a Transit Distance of 97,788,036.08 km.

Now this seems wrong as Distance A which should be the distance from the primary to the zenith or nadir is only 64,500,000 km which is well below the 433,890,326 km from the table.

According to page 259 of SO I find that

Time = 2 x square root (Distance / Acceleration)

Where:

Distance = 97,788,036.08 km * 1,000m

Acceleration = 9.8 m/s/s

Plugging these in I get a Transit time of 2.31 days or a little less than half the time from the table.

What am I doing wrong?
