Back to Math And Terraforming There are a few planetary parameters that are easy to work with. Using Microsoft Excel, we can see the behavior of any theoretical planet. The following is an example I use. Some formulas are adapted from books and sites, while some are my invention. In this table, I left row A for column names, while row B is for the parent star. There, we should write the Solar Constant and the solar mass. If you want to work with a system with multiple stars, see additional instructions below.
