Stars and planets
There are many types of stars and planets, each with their own advantages and disadvantages in terms of gameplay value.
When picking a star to construct a Dyson sphere around, it's highly recommended to do it around a star with the highest luminosity (L☉) as possible, as many stars can have more than double (~2 L☉) if not triple (~3 L☉) the energy output than the starter system's star (~1 L☉). This makes the process much less time-consuming and considerably more effective than even constructing multiple Dyson sphere around lower-luminosity stars.
Some rare veins and ores can only be found on certain types of planets, and are impossible to find anywhere else.
Types of planets
Planets can be split into several categories. Each has their own rule of spawning when star system is generated.
- Habitable: Planets that have enough liquid water to sustain the existence of life. These can be found in their star's habitable zone. A typical habitable planet has abundant fossil resources such as Coal and Crude Oil.
- Hot: Planets with very high temperature and exotic oceans which contain various fluids. These can be found orbiting close to their star. A typical hot planet has abundant metallic resources such as Iron Ore and Titanium Ore.
- Frozen: Planets with very low temperature and frozen-over oceans of ice. These can be found orbiting far from their star, near the edge of their system. A typical frozen planet has abundant crystalline resources such as Fire Ice.
- Barren: Planets devoid of liquids. These may spawn anywhere in a system. Most barren worlds have abundant non-metallic resources such as Stone, Silicon Ore, and Soil Piles.
- Giant: Huge, gaseous planets without any solid landmass. Icarus cannot land on these planets, but can gather resources from low orbit.
Each planet type has several attributes:
- Common resources: The types of common resources that are sure to spawn.
- Rare resources: The type(s) of rare resources that MAY spawn.
- Ocean: Whether or not the planet has an ocean, and what the ocean is composed of.
- Construction area: The expected percentage of landmass that can be utilized for construction if no Foundation is used.
- Wind energy ratio: The expected effectiveness of Wind Turbines. Zero wind energy ratio means that no atmosphere exists.
- Solar energy ratio: The expected effectiveness of Solar Panels. This largely depends on the planet's distance from its star and the star's type.
|Mediterranean||A lush and tropical habitable world covered with oceans.
Mediterrean planets are abundant with basic resources and oil, but lack advanced resources.
Only one of these planets exists in each cluster, and it is the player's starting planet.
|Ashen gelisol||A frozen world covered with rock and soil.
Ashen gelisol planets generally contain a large number of various resources, but their thin atmosphere and lack of fuel can easily lead to power shortages.
|Arid desert||A dry, barren world covered with vast deserts.
Arid desert planets generally contain unbalanced deposits, good for mining certain resources.
Thanks to their active atmospheres, these planets are a great place to capture wind energy.
|Barren desert||A barren world with no atmosphere, its surface covered with craters, lifeless dirt, and rock. These planets are similar to the moon that orbits Earth.|
|Crystal desert||(Added in Ver.0.9.26) A barren world covered with deserts of various crystalized matter, and possessing an active atmosphere.
Crystal deserts contain deposits of various crystal resources, especially Optical Grating Crystal, which always appears in vast numbers. Strong winds provide a great source of energy, making these planets ideal for building mining sites.
|Frozen tundra||(Added in Ver.0.9.26) A frozen world covered by tundra and snow, and possessing an active atmosphere.
These planets consist of black soil and white snow and contain large numbers of common and rare ore deposits. Naturally flat terrain also allows the construction of large manufacturing plants.
|Gobi||A dry, barren world covered with deserts and possessing a thin atmosphere.
Gobi planets contain mountains, so they're a great source for soil piles. The rest of their terrain is naturally flat, making them ideal places for large-scale construction.
These planets contain large numbers of deposits, but their lack of naturally-occurring Titanium Ore makes it hard to handle advanced production without importing Titanium.
|Hurricane Stone Forest||(Added in Ver.0.7.18.6914) A hot, barren world with an active atmosphere. Strong winds eroded the surface and caused its unique terrain.
These planets possess great wind and solar energy ratios and contain many different deposits, perfect for mining sites.
Due to their extreme atmosphere, these planets contain vast amounts of Soil Piles.
|Ice field gelisol||A frozen planet covered in ice that may have pockets of water scattered around the surface. These planets are similar to Jupiter's moon Europa.
Large veins of Fire Ice can be found on these planets. Since they're usually far away from their star and have weak winds, they're terrible sources for renewable energy. Use of Thermal Power Stations is recommended.
|Lava||A hot world covered with lakes of molten lava.
Lava planets usually contain vast amounts of metal ores, and these planets can use Geothermal Power Stations to freely harvest energy. Good for mining sites.
|Oceanic jungle||A habitable world that covered with vast tropical jungles and huge bodies of water.
Oceanic jungles are filled with organic beings, so they have rich deposits of rare organic resources such as Crude Oil. However, the amount of water covering their surfaces makes them better suited for mining than manufacturing, unless the player has enough Soil Piles.
|Pandora swamp||(Added in Ver.0.9.26) A habitable world covered in bizarre plants, without any notable bodies of water.
Pandora swamps have rich deposits of organic resources, but are somewhat lacking in minerals. They are unusual among habitable worlds in that they have no oceans.
|Prairie||A habitable world similar to Mediterranean planets, with fewer bodies of water and more grasslands.
Prairies have rich deposits of organic resources and balanced mineral deposits. However, Titanium Ore is quite rare on Prairies.
|Red stone||A habitable world similar to Mediterranean planets, but with red soil and mushrooms growing all across the surface.
They have similar resources to Mediterranean planets, but also spawn other rare organic resources.
|Rocky Salt Lake||(Added in Ver.0.7.18.6914) A barren world covered with vast salt flats and some normal soil.
These planets contain various minerals, have rich deposits of Silicon Ore, and have naturally flat terrain, making them perfect for mining and manufacturing alike.
|Sakura Ocean||(Added in Ver.0.7.18.6914) A colorful habitable world covered with oceans and exotic plants that contain Sulfuric Acid as sap.|
|Savanna||(Added in Ver.0.9.26) A habitable world covered by great plains. Only a handful of bodies of water exist.
Savannas have similar resources as Prairies, but spawn more common resources and fewer rare ones.
|Scarlet Ice Lake||(Added in Ver.0.7.18.6914) A frozen world covered by scarlet soil and large swathes of frozen ocean.|
|Volcanic Ash||A hot world covered with volcanic ash and pools of Sulfuric Acid.
Volcanic Ash planets have no rare resource deposits, but their oceans of Sulfuric Acid can greatly simplify the player's production line.
|Waterworld||A unique habitable world covered almost entirely by a single large ocean.
Constructing any large infrastructure on their surfaces will be resource and time intensive. However, these planets contain huge deposits of Crude Oil and Spiniform Stalagmite Crystals that make the efforts worthwhile. Better carry lots of Soil Piles and Foundations before visiting!
|Gas Giant||Gas Giants are commonly found around the universe, and are a good source of Deuterium and Hydrogen by using Orbital Collectors.
Notably, there are 3 different types of Gas Giants: red, brown, and teal. The teal Gas Giants produce more Deuterium than the others.
|Ice Giant||Ice Giants are less commonly found around the universe, but are a good source of Fire Ice and Hydrogen by using Orbital Collectors.|
According to this reddit post, all terrestrial planets appear to follow the same grid layout:
5x20 (Including the pole, forms a 9 diameter disk around the pole) 5x40 5x80 5x100 10x160 10x200 15x300 15x400 25x500 25x600 50x800 80x1000 Equator (1x1000)
These grids meet at latitudes of approximately 88, 86, 84, 82, 79, 75, 70, 65, 55, 46, 28, and 0 degrees North and South.
When building on a seam between the different bands, buildings will snap to the band closest to the equator.
|Class M star||The lowest mass stars are commonly referred to as Red Dwarf stars. They are the most abundant class of star, but their luminosity is very low, making it very impractical to construct Dyson spheres or even Dyson swarms around them.|
|Class K star||These low-mass stars typically have a luminosity of < 1 L☉, making them poor sites for construction of Dyson spheres. Dyson swarms may still be of some use, since they are much less resource-intensive.|
|Class G star||This class of star is the one that our Sun falls into. They typically have a luminosity of ~1 L☉. While they can make good use of Dyson spheres and Dyson swarms, higher-luminosity stars may be a more suitable location for Dyson sphere construction.
The starting system is always around a class G star.
|Class F star||These stars have a higher luminosity than Class G stars but are around the same size. This makes them better sites for construction of Dyson spheres, if no Class A or higher stars are nearby.|
|Class A star||This class have fairly high luminosity, while not being particularly large. This makes them good sites for construction of Dyson spheres if materials are limited, or there are no nearby Class B or O stars.|
|Class B star||These stars have a high luminosity, while not being as large as Class O. This makes them excellent sites for construction of Dyson spheres if materials are more limited.|
|Class O star||The brightest star type, ideal for constructing Dyson spheres around them. However, they also tend to be the largest, and so require more materials to do so.|
|Giant star||Giant stars are special stars that are basically larger versions of main sequence stars. Giants are generally >10R⊙ and have higher luminosity than their main sequence counterparts. Depending on their spectral class, they are referred to as Red, Yellow, White, or Blue Giants. M-class Red Giants and B-class Blue Giants are the most common giant stars in the universe, while Yellow and White Giants are extremely rare.|
|White Dwarf||A stellar remnant left over after the death of a star that was not massive enough to form a neutron star or black hole, composed of electron-degenerate matter. Low luminosity makes them poor sites for construction of Dyson spheres. Dyson swarms may still be of some use, due to their considerably lower resource requirements.|
|Neutron Star||A stellar remnant following a supernova, composed of neutrons with a shell of electron-degenerate matter. Low luminosity makes them poor sites for construction of Dyson spheres. Dyson swarms may still be of some use with their much lower resource requirements.
Only a single Neutron Star generates per cluster. Due to their low temperature and luminosity, all planets orbiting a Neutron Star are frozen worlds.
Neutron Star systems are one of the only places that Unipolar Magnets can be found.
|Black Hole||A massive stellar remnant following a supernova, it has been crushed into a point so dense and with such immense gravity that light itself bends around it and is sucked in. They are usually surrounded by an accretion disc. Their extremely low luminosity makes construction of Dyson spheres or Dyson swarms a vanity project, as they will produce little power.
Like Neutron Stars, only one Black Hole generates per cluster, and all planets orbiting Black Holes are frozen worlds. Black Hole systems are the only place outside of Neutron Star systems where Unipolar Magnets can be found.

State of stellar objects
Planets can have multiple physical attributes and states, which are listed below.
|Tidal locking (TL)||Planets that has the same rotational period as orbital period, and consequently has one side permanently facing its host star or planet. Very useful to capture the host star's energy via solar panels and/or ray receivers|
|Sattelite (SAT)||Astronomical objects that orbit another object that isn't a star, or in simpler terms, a moon. The starter planet is one example of such object. However, building EM-rail ejectors would be problematic, as the orbiting parent can block the sun, rendering them useless until the orbiting object passes, this decreases the time the EM-rail ejectors can fire sails, and decreases their effeciency.|
|Reverse Rotation (RR)||The astronomical object in question rotates in the reverse direction, or clockwise when viewed from one of the poles.|
|Horizontal Rotation (HR)||The planet has an axial inclination close to 90° causing it to rotate around a horizontal axis when viewed from the stellar poles. Still experiences seasons.|
|Orbital Resonance (OR)||The planet has longer days. Orbital resonance 1:2 would mean a cycle of two days per year and 1:4 four days per year. Orbital resonance of 1:1 would be tidal locked.|
|Plural Satellites (PS)||The gas giant has two planets orbiting it instead of one. The planets will sometimes be only 1000 meters away from each other.|
