(Official) Stellar Neighborhood V1.4 - 74 Bodies

Interstellar travel has arrived to Simple Rockets 2!

Stellar Neighborhood brings 74 high quality and unique planetary bodies to your PC or mobile, with a total of 8 planetary systems on real interstellar scales. The game world extends to 14 light years, to the farthest star system in the pack, Wolf 1061.

The experience is completely bug free and stable, lacking stuttering and image artifacts in map view, as well as mobile friendly. In fact, the pack was developed on mobile. This system pack is based on real star systems and its home system is Sol, Earth.

The star systems were designed without a great degree of realism, and were instead with the premise of delivering the player with a unique experience, with each planet distinctly different from one another. Getting to these worlds will not be easy though, Hohmann transfers will not get you there.

To conquer them, you must master interstellar navigation and brachistochrone transfers, which will be outlined in a tutorial guide at the bottom of this page. At the end of the day, you will be left with amazing sights and the great achievement of interstellar navigation.

Luhman 16 (6.52 ly): A pair of brown dwarfs orbiting each other, the system holds a total of 3 planets and 2 moons for you to explore. Orbiting Luhman 16 A is 2 planets, a small tidally locked carbonia with black canyons of oil and a large red gas giant with a beautiful red ring system as well as a couple of moons. Inside its atmosphere are huge swirling storms that contrast’s planet’s red tint with black. Orbiting Luhman 16 B is a single rocky heavy-weight. An atmosphere is present here, but not dense enough to fly in.

Tau Ceti (11.90 ly): A 78% Sol mass yellow dwarf, it hosts 4 planets, 2 moons, and a binary moon system. Unique to Tau Ceti is a toxic, boiling hot oceania devoid of land, a habitable world with a massive continent spanning impact crater filled with water, a superhabitable terra around a gas giant, and an icey binary pair that endlessly dance around each other. With so much water and habitable planets in the system, Tau Ceti is truly a paradise.

Barnard’s Star (5.98 ly): A 14% Sol mass red dwarf hosting 3 planets and 2 moons to explore. Unique to it is a habitable mountainous and craggy icy tundra and a toxic atmospheric moon with craters of sulfuric acid heated by its gas giant parent.
Wolf 1061 (14.04 ly): A 29% Sol mass red dwarf featuring 4 planets and 2 moons to visit. Among the system is a stormy ringed hellscape battered by eternal lightning storms, a world spanned with deep canyons as if chiseled into the surface by a god, and a rocky desert moon almost skimming its gas giant parent’s atmosphere.

Alpha Centauri (4.37 ly): A trinary star system holding 7 planets and 3 moons to discover. The system is composed of Alpha Centauri A and B and Proxima Centauri. Notable here is a green gas giant holding a mysterious green luminescent substance in the atmosphere, a cold gas moon, a mountainous desert world with blue soil mainly composed of copper, and a tidally locked world frozen on its dark side and ocean on its day.

Epsilon Eridani (10.47 ly): A single orange dwarf lighting up 4 planets and 4 moons. In this system is a small dense planet with oceans of reflective mercury, a habitable terra with a muddy brown surfaces and green-blue rivers of water, a cold almost venusian like world debated whether or not to have a surface, a moderate ocean moon, and a ringed rocky moon holding lava within a large impact crater.

Sirius A (8.61 ly): A binary system composed of a 206% Sol mass main sequence star and a 102% Sol mass white dwarf. Here are 6 planets and 2 moons to discover. Among its worlds is a hot hellscape with blue lava from burning sulfur and a sulfuric atmosphere, a moon holding oceans of liquid methane, and the dense remnants of two gas giants.

Sol (Home): Lastly, our home system. Included are Venus, Earth, Luna, Mars, Jupiter, Io, Ganymede, Saturn, Enceledus, and Titan.

And many more unique planets and moons which were not described!

As a final note, in order to get to these systems you must develop or download an ion powered starship with at least a dV of 1/3 the speed of light (100,000,000 m/s). Another option is enabling infinite fuel in the dev console by entering “MLI”. The dev console keybinding is unbinded by default.

Linked is a guide on how to do the former option:
