Cassiopeia IV-a is an explorable moon in the Eta Cassiopeia system in Starfield. A community guide reports eight inorganic resources and six flora on the moon, but that list is not confirmed by an official moon-specific database; check your in-game scanner before treating it as definitive. Here’s where to find the moon and how to approach its survey.

Where is Cassiopeia IV-a?

Open the Starmap and locate the Eta Cassiopeia system, then select Cassiopeia IV-a. Game8 identifies it as an explorable moon in that system, and a Steam Community guide also lists the moon under Eta Cassiopeia. The community guide labels the system level as 20; treat that as a guide listing rather than a measure of the moon’s resources or survey difficulty.

Sources: Game8’s Cassiopeia IV-a location and survey page and the Steam Community guide “MAXIMUM EFFORT”.

What resources and flora are reported on Cassiopeia IV-a?

The Steam Community guide reports the following inorganic resources and flora. These are useful leads, not an official or independently verified current-game checklist.

How to survey the moon

Starfield uses the same general exploration process on Cassiopeia IV-a as on other worlds. Xbox Wire’s exploration guide explains that an orbital scan can show basic resources, that the Scanning skill can reveal rarer ones, and that the planet map can help you choose a landing area. The Starmap also presents world information such as type, gravity, temperature, atmosphere, and whether flora or fauna are present. These are general game mechanics, not moon-specific guarantees.

  1. Find the moon: In the Starmap, travel to Eta Cassiopeia and select Cassiopeia IV-a.
  2. Scan from orbit: Review the available world and resource information before landing. If a resource is not visible, your Scanning skill may affect what the scan reveals.
  3. Choose a landing area: Use the planet map’s available resource information to guide your landing choice. The sources do not establish a guaranteed biome or landing site for any particular resource on this moon.
  4. Survey on the surface: Use your scanner to find and scan survey targets, then check its remaining counts as you explore. For planetary traits, look for unusual or anomalous surface features and scan them.
  5. Check completion in-game: Use the scanner’s own survey status to see what remains rather than relying on a third-party list as a complete checklist.

For the general mechanics, see Xbox Wire’s “Starfield Starters: An Explorer’s Guide to Planet Hopping”, published September 1, 2023.

What is not confirmed about Cassiopeia IV-a?

The available location and community listings do not establish a complete moon-specific checklist for fauna, planetary traits, biomes, or points of interest. Nor do they verify that the reported resource and flora entries are unchanged in the current version of the game. Use your in-game scanner for the authoritative status of your own survey.
