Summary
There are many types of stars and planets, each of which has their own advantage, and disadvantages in terms of gameplay value. This page is dedicated to categorize all astronomical objects and phenomena, and describe them.
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 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☉), which is much less time consuming, and more effective than building one or even two additional dyson spheres orbiting neighboring stars.
Some rare veins and ores can only be found on certain types of planets, but on the other hand, it can also be impossible for those materials to naturally occur in other planets.
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 can hold enough liquid water to sustain the existance of lifeform. Can be found inside habitable zone. A typical habitable world have abundant fossil resources such as Coal and Crude Oil.
- Hot: Planets with very high temperature and exotic oceans which contains various fluids. Can be found near the star. A typical hot world have abundant metalic resources such as Iron and Titanium.
- Frozen: Planets with very low temperature and ocean exists in the form of ice. Can be found near the edge of system. A typical frozen world have abundant crystaline resources such as Fire Ice.
- Barren: Planets devoid of any form of fluid. Can spawn anywhere in a system. Most barren worlds have abundant non-metalic resources such as Stone, Silicon, and Soil Piles.
- Giant: Planets without usable landmass. Icarus cannot land on these planets, but can mine for resources from orbit.
Table contents:
- Common resources: type of common resources that will spawn on this world.
- Rare resources: type of rare resources that MAY spawn on this world.
- Ocean: whether ocean exists on this world or not, and its contents if ocean exists.
- Construction area: expected percentage of landmass that can be directly used for construct.
- Wind energy ratio: expected effectiveness of wind turbine. Zero wind energy ratio means no atmosphere exists.
Solar energy ratio is a variable which largely depends on distance from the star and the type of the star.
| Name | Description | Image | Surface view |
|---|---|---|---|
| Mediterranean | A lush and tropical habitable world covered with oceans.
Mediterrean planets are abundant with basic resources and oil, but lacks advanced resources. There is only one of these planet types in the cluster. It is the player's starter home planet. |
||
| Ashen gelisol | A frozen world covered with rock and soils.
Ashen gelisol generally contains large number of various resources, but thin atmosphere and lack of fuel can easily leads to power shortage. |
||
| Arid desert | A dry, barren world covered with vast desert.
Arid desert generally contains unbalanced deposits, good for mining certain resources. Thanks to its active atmosphere, these planets are a great source for capturing wind energy. |
||
| Barren desert | A barren world without atmosphere, covered with craters, lifeless dirt and rock. Similar to the moon that orbiting our Earth.
Since there's no atmosphere, wind turbines are useless, there are no oceans either, but it has the biggest construction area, and can be a decent source for soil piles and stones.
|
||
| Crystal desert | (Added in Ver.0.9.26) A barren world covered with desert of various crystalized matter, and possess active atmosphere.
Crystal desert contains deposits of various crystal resources, especially Optical Grating Crystal, which always appeas in vast number. Strong wind provide great source of energy, makes it ideal for building mining site.
|
||
| Frozen tundra | (Added in Ver.0.9.26) A frozen world covered by tundra and snow. Possess active atmosphere.
A world consised of black soil and white snow. It contains large number of normal and rare ore deposits. Flat terrain also allows the construction of large manufacturing plants.
|
||
| Gobi | A dry, barren world covered with gobi desert and thin atmosphere.
Gobi does contain mountains, so they're a great source for soil piles. Flat terrain also make it an ideal place for large scale construction. Contains large number of deposits, but absence of Titanium make it hard to handle advanced production.
|
||
| Hurricane Stone Forest | (Added in Ver.0.7.18.6914) A hot, barren world with an active atmosphere. Strong wind eroded the surface and caused its unique terrain.
It generally possess great wind and solar energy ratio, and contains many different deposits, perfect for mining sites. Due to extreme atmosphere, this world contains vast number of soil piles. Simply build something to get it.
|
||
| Ice field gelisol | A frozen world covered with ice, and may have pockets of water scattered around the surface. Similar to europa that is orbiting Jupiter.
Large veins of Fire Ice can be found around such planets. Since they're usually far away from their orbiting star, and have weak winds, they're terrible sources for renewable energy, the use of thermal power stations is recommended.
|
||
| Lava | A hot world covered with lava lakes.
Lava planet usually contain vast number of metal ores, and lava lakes provide a perfect source of thermal energy. Good for mining sites.
|
||
| Oceanic jungle | A habitable world that covered with vast tropical jungle and huge waterbody.
Oceanic jungle is filled with organic beings, so it has rich deposits of organic rare resources such as Crude Oil. It has huge ocean coverage, so it's better used for mining unless you have enough soil piles.
|
||
| Pandora swamp | (Added in Ver.0.9.26) A habitable world without notable waterbody, and covered with strange plants.
Pandora swamp has rich deposits of organic resources, but slightly lack of minerals. It's a rare habitable world type which lacks ocean.
|
||
| Prairie | A habitable world similar to mediterranean planets, with less waterbodies and more grasslands.
Prairie have rich deposits of organic resources and balanced mineral deposits. Be careful that titanium deposit is quite rare here.
|
||
| Red stone | A habitable world similar to Mediterranean planets, but the soil is more reddish, and the surface is covered with mushrooms.
It has similar resource spawn to Mediterranean planets, but it will spawn other organic rare resources.
|
||
| Rocky Salt Lake | (Added in Ver.0.7.18.6914) A barren world that covered with vast salt flats and some normal soils.
It contains various minerals, has rich deposits of Silicon, and have flat terrain, so it can be used as mining site or manufacturing plant.
|
||
| Sakura Ocean | (Added in Ver.0.7.18.6914) A colorful habitable world that covered with oceans and exotic plants that contains Sulfuric Acid as sap.
Sakura ocean has similar resource spawn to Oceanic jungle, which rich with organic resources such as crude oil and coal.
|
||
| Savanna | (Added in Ver.0.9.26) A habitable world covered by great plains. Only a few waterbodies exists.
Savanna has similar resource spawn pattern to Prairie, but has only water and more basic resource deposits, but rare resources are more sparce. |
||
| Scarlet Ice Lake | (Added in Ver.0.7.18.6914) A frozen world covered by scarlet soils and large chunks of frozen oceans.
Scarlet Ice Lake is a barren frozen world with large deposits of copper and titanium, but lack of other resources. Important: Player can walk and place building directly on frozen ocean, but it still costs foundations.
|
||
| Volcanic Ash | A hot world that covered with volcanic ashes, and pools which contains Sulfuric Acid.
Volcanic Ash has no rare resource deposits, but it's the only planet type that has sulfuric acid pools. Due to complexity of producing sulfuric acid, a volcanic ash planet will greatly simplify player's production line. |
||
| Waterworld | A special habitable world covered almost entirely by a single large ocean.
Constructing any large infrastructure on their surfaces will be resource and time intensive. It contains huge deposits of crude oil and spiniform stalagmite crystals which may offset those constraints for some players. Better carry lots of soil piles before visiting this planet!
|
||
| Gas Giant | Gas Giants are commonly found around the universe, and are a good source of Deuterium and Hydrogen by using Orbital Collectors.
There exists two kinds of Gas Giant with different color, and they produce different number of each resources. The blue one contains more Deuterium than the brown one. |
||
| 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.
Stellar objects
| Class | Image | Description |
|---|---|---|
| Class M star |  |
The lowest mass stars are commonly referred to as Red Dwarf stars. They are the most abundant class of star, however, their luminosity is very low, making it very impractical to construct Dyson Spheres or even Dyson Swarms around them. |
| Class K star |  |
A low mass star, they typically have a luminosity of < 1 L☉, making them poor sites for construction of Dyson Spheres. Dyson Swarms may however still be of some use with their much lower resource requirements. |
| Class G star |  |
This is the class of star of which the Sun is a standard member. 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 better location for Dyson Sphere construction.
The starting system is always around a class G star. |
| Class F star |  |
These stars have a higher luminosity while being of similar size to Class G stars. This makes them better sites for construction of Dyson Spheres, should no Class A or above stars be 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 more limited, or there are no nearby Class B or O stars. |
| Class B star |  |
This class 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 |  |
Can be of any spectral class that main sequence stars belong to. Giants are >10R⊙ (with exceptions) and have higher luminosity than their main sequence counterparts. Depending on spectral class, they are referred to as Red, Yellow, White and 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 following a nova, composed of electron-degenerate matter. Low luminosity makes them poor sites for construction of Dyson Spheres. Dyson Swarms may however still be of some use with their much lower resource requirements.
Non-giant planets orbiting White Dwarves are guaranteed to have veins of Fractal Silicon, Kimberlite Ore and Optical Grating Crystal. |
| 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 however still be of some use with their much lower resource requirements.
It is one of the rarest stars, only one will be generated in a cluster. Due to low temperature and luminosity, all planets orbiting Neutron star are frozen world. Unipolar Magnets can only be found on host planets orbiting a Neutron Star or Black Hole. |
| Black Hole |  |
A massive stellar remnant following a supernova, it has collapsed behind an event horizon. 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.
It is one of the rarest stars, only one will be generated in a cluster. Due to low temperature and luminosity, all planets orbiting Black Hole are frozen world. Unipolar Magnets can only be found on host planets orbiting a Neutron Star or Black Hole. |

State of stellar objects
Planets can have multiple physical attributes and states, which are listed below.
| Name | Description | Image |
|---|---|---|
| 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. |
