All planets orbit in the same plane without any dynamic interaction. Planetary Systems like the original Orbits is not intended for simulation of elongated elliptical orbits, high inclination orbits, orbital resonances etc. And you’ll never generate systems expanding beyond 9 OU or so. You’ll never have second planet close enough to the habitable zone so you’ll never generate a lovely sci-fi setting with two or more habitable planets in the system. You’ll never have two planets between sun and main planet as in our Solar system, only one is possible. The Planetary Systems script, inherited from Orbits, limits possible layouts. Tionisla for example has almost all our planets except the Neptune analog, but with the following arrangement: Like the original Orbits, Planetary Systems generates more compact systems than our real Solar system. ![]() So you’ll have not only unique planet layout for every system, you’ll have unique value of local year. Modified script uses orbital period of main planet calculated on base of sun mass and distance (this part of work is provided by AstroLibrary external function in Sun Gear). Original Orbits has fixed orbital period of main planet 300 days (standard year of canonic Lave). So you can simulate large moons such as Titan or Ganymede. You can see systems with only gas giants except main planet or with only terrestrial planets.ĭiscriminating borderline between large moon and small planet is raised from 1000 to 2500 km (from 10,000 to 25,000 m in game units). It seems to be similar to our Solar system layout with exception of super-earth, but really Orbits generates wide range of possible layouts. Two gas giants like Jupiter or Saturn without rings.Venus-like planet or desert Terra-like planet.These planets are divided onto classes based on radius: The main reason is provide more diversity for the initial data, used by PlanetEngine (about PlanetEngine a bit later) Ten radius variants for every planet class is not just for visual diversity (it is hard to notice visual difference between 34 km radius without a specially planned experiment!). The script preudo-randomly selects one from ten variants for every planet class in the generated subset. Mini-terra, for example, are presented with radii of 2750, 2775, 2800, and 2975 km. Like the original Orbits, this script generates a planet subset, selecting planets from the ist on pseudo-random basis: but technically there are 10 variants for every planet class in the ist. ![]() The maximum additional number of planets in a system has been raised from 7 to 8. ![]()
