Celestial Analysis

Source Galaxy Exploration Manual pg. 35
You use a starship’s computer to analyze gravity-well data and determine the nature of one or more celestial bodies.

Activity: You spend the day as a starship’s science officer, analyzing pinpointed gravity wells to identify the type of astronomical objects at their core. The number of gravity wells you can analyze in one day depends on the number of nodes the starship’s computer has: 1 gravity well with a basic computer or mononode, 2 with a duonode, and so on. At the end of the day, attempt a separate DC 30 Computers or Physical Science check for each astronomical object you attempt to identify. You gain a +1 bonus to such checks if your starship has a general science lab or a +2 bonus if it has a physical science lab. You also can apply the bonus normally granted by your starship’s computer. You can’t take 20 on this check.

Results: On each success, you determine whether the gravity well is caused by a gas giant, a terrestrial world, a large asteroid, or an irregular world (including those science fantasy constructions that stretch the concept of a world, per the GM’s discretion). If your result exceeds the DC by 5 or more, you also learn the number of large satellites (such as moons) the astronomical object has, if any.
