Quick note this evening, to report that I’ve caught an erratum in Architect of Worlds. Somewhat significant one, too, affecting the generation of Galilean-like satellites for gas giant worlds. Fortunately, it’s an easy fix.

In the formula for the mass of a gas giant’s major satellite at the top of page 85, the multiplier up front should be 10^-5 instead of 10^-6.

Essentially, we’ve been developing satellites that are one-tenth as massive as they should be, if we’re going to match the results we see in our own planetary system.

I’ve reported this to Ken Burnside, so it should appear in the Ad Astra Games errata at some point.
