1) Firstly, there goes Jupiter as an M6V type red dwarf. I did not change orbital specifics of the Galilean moons. Io ends up ripped apart by tidal forces and rest of the moons are now barren rocks stripped off any volatiles. Outer planets are located twice as far, otherwise the orbits would be unstable due to Jupiter being ~100 times more massive. The asteroid belt would not be stable too, so I removed it.

2) In the second case, Jupiter is the exact twin of the Sun. Galilean moons are now dwarf planets flanked by Saturn on the outside (Otherwise I would have to make it circumbinary, which is the case for the red dwarf Jupiter already). Orbital stability is more of an issue here. Inner planets orbit closer to the original Sun, so Earth is basically deep fried, but there are surprises to weight this out.

System names in SE are: Sun and M6V Jupiter, Sun and G2V Jupiter

I disabled night side lights due to a bug when placed in a binary stellar system.

-Yautja Prime
-Game Preserve Planet
-System from Alien: Covenant


-Predator home world


-When the prey realizes that they are not even on Earth anymore


-Planet 4 as approached by the Covenant

System layouts that are not realistic:
-Game Preserve Planet would just crash into the closest moon.
-System from Alien: Covenant is based on the schematics shown before the crew decides to go there. (Highly inclined and crossing orbits, Planet 4 is technically not fourth from it's star)

This is Earth as it appears in Star Trek: First Contact when the Borg return back in time to assimilate it.

The addon replaces Earth in our solar system. Just throw it into addons/catalogs/planets.

In the film, the atmosphere is said to contain high concentrations of methane, carbon monoxide and fluorine. "High concentrations" may mean anything, but I decided not to make them majority elements. Yet, the atmosphere is probably toxic enough to kill a human anyway. Also, SE does not support fluorine so I substituded it with chlorine, Cl₂.

Here is the Sirius Sector from the 2003 game, Freelancer, sort of star cluster I placed roughly 1000 light years from Earth. This is probably the most unrealistic jumble of colorful nebulae the game developers could come up with, but I think my re-creation turned out decent. It looks better from the inside. Since I do not suppose that many people know what a 15 years old game is about, I suggest browsing through either YT or this wiki. Some systems may not be entirely plausible, like inhabited planets with blue B class stars for a sun, or one orbiting a white supergiant.

Stellar systems in the game are rather empty, most contain 2-3 planets, some just the star. Here is the list, divided into regions:
-Liberty: New York, Texas, Colorado, California, Alaska
-Rheinland: Hamburg, New Berlin, Frankfurt, *Stuttgart, *Dresden
-Kusari: Honshu, Shikoku, New Tokyo, Kyushu, *Hokkaido, Tohoku
-Bretonia: Leeds, Edinburgh, Manchester, New London, Cambridge, Dublin
-Independent Worlds: Cortez, Bering, Hudson
-Border Worlds: Sigma-13, Sigma-17, Sigma-19, Omega-3, Omega-11, Tau-23, Tau-29, Tau-31
-Edge Worlds: Omega-41, Tau-37, *Omicron Alpha, Omicron Beta, *Omicron Gamma, *Omicron Theta, *Omicron Minor, Omicron Major, North Unknown, South Unknown
*)Contains colored comets (like the one I use as my intro image on this page). Some systems in the Freelancer game possess various nebulae, so I decided to substitute these for comets. Some of these are disappointing, others are a good eye candy. Some systems are said to be young, possibly with protoplanetary disk. These may be updated later, when PP disks and/or zodiacal light are implemented.

Excluded systems, because in the game, they do not even contain a star. Basically just interstellar space. Also left off because placing asteroid rings around StarBarycenters into otherwise empty system was shutting down my SE.
-Galileo, Kepler, Magellan, Chugoku, Omega-5, Omega-7

I also included wormholes (called jump holes in Freelancer). One possesses a ring. There are also ringed stars, but SE does not seem to like this idea so I had to use an asteroid as a base for the ring system. I also have to select the asteroid or enable markers to see the ring. Here is the list of asteroids used as bases for rings:
-Frankfurt > Dresden Jump Hole Asteroid Companion
-North Unknown Rings 1
-North Unknown Rings 2
(The star has a double ring system)
-Omega-41 Rings
-Tau-37 A Rings

Planet Munich with a ringed wormhole far in the background


Planet Kurile is circumtrinary. (Is that even a word?...)
