So, I got tired of the literally hundreds of rolls involved in randomly generating a solar system for sandbox-style sci-fi games, so I decided I would automate the process and make a spreadsheet to do the work for me. The spreadsheet is based on Larry Moore's Star System Generation document and determines details about every planet in the solar system with a single click.
Please find the most current version at my site, in OpenOffice.org spreadsheet format for best functionality and compatibility.
