Mass Effect (PC) Guide › Essentials › Planetary Database

Planets A-J

This section lists all the planets in the star systems you’ll visit. Below you’ll find information and maps to all the places you can visit.

While many of the galaxy’s planets have points of interest—collectibles or assignments—a large number of them hold no mysteries or elements.

These are listed by name under "Inert Planets" in each star system section. You can glance at them as you play but they have no features that will progress your game.
