Starfield players have discovered a few planets that reference popular sci-fi media, including Halo: Reach and Star Trek in the Eridani system, and Warhammer 40K in the Wolf system.
With roughly 1000 planets to explore and stumble upon in Starfield’s vast galaxy, it’s no surprise that Bethesda has thrown in a few references to some of the most popular franchises that involve futuristic space travel.
Below, we go over which planets are referenced from Halo, Star Trek, and Warhammer 40k and how to pay them a visit in Starfield.

The planets from Halo, Star Trek, and Warhammer 40k referenced in Starfield are as follows:
Here is each planet in more detail:
Halo: Reach – Eridani II
Eridani II in Starfield is a reference to the planet Eridani II from Halo: Reach. The Eradani system is based on a the real star system, Epsilon Eridani, in both Halo: Reach and Starfield.
The system ticks all the boxes to contain habitable planets and is one of humanity’s safest bets for far-future space travel.

In Halo: Reach, Eridani II has a lush climate featuring dense green forests, large mountains, and a breathable atmosphere. The climate is very similar in Starfield’s version of Eridani II, allowing Halo fans to explore the planet in a new light.

Some fans have already set up outposts on Eradani II in Starfield, paying homage to Halo:

Despite this, Eridani I seems to be as close as you can get to visiting Star Trek’s planet Vulcan in Starfield, as it is in the same constellation.
In Star Trek, Vulcan is a habitable planet known for its temperate climate and many deserts. Starfield’s Eridani I is very similar, with large desolate rocky desert areas to explore. Although, it doesn’t seem that habitable.

Still, some are calling it home and are roleplaying it as part of the Vulcan homeland in Starfield.

Warhammer 40k – Cthonia – Chthonia
The planet Chthonia in Starfield seems to be a direct reference to the planet Cthonia in Warhammer 40k. It is located in the Wolf system in Starfield.

This Reddit user has figured out that the planet Chthonia in Starfield is linked to Warhammer 40k:
In Warhammer 40k, the planet Cthonia is the home planet of the Luna Wolves Legion. As (the differently spelled) Chthonia planet is located within the ‘Wolf’ system in Starfield, it’s pretty safe to assume that Bethesda is directly referencing the Warhammer series here.
In Warhammer lore, Cthonia is described as a “barren and impoverished” world that has been stripped of its natural resources and was abandoned long ago.

Whether intentional or not, Chthonia in Starfield bears quite a few resembles to this description. The planet is barren and empty, though there are still some resources to mine when walking along the planet’s surface.
