In this app you can explore almost any moon or planet of our solar system and visit remarkable nearby stars and see their location in the Milky Way. But you can also change existing bodies or add new ones and make a solar system of your own. The simulation will then act as a gravity and physics sandbox and recalculate orbits in line with Newton's laws.

Version History - Added comet C/2024 E1 (Wierzchos): visible with binoculars/telescopes in early 2026 (best in the southern hemisphere). - Added comet C/2025 R3 (Pan-STARRS): may become very bright in April 2026. - Added comet C/2025 L1 (ATLAS): moving toward the inner Solar System, expected to brighten in spring. - Fixed incorrect units in manual planet rotation input. - Banned unskippable ads (hopefully for good!). 0.365 Feb 10 - Fixed supernova's bugged lighting - Fixed planetary night lights staying on during daytime - Increased memory page size - Unity security fix - Other bug fixes 0.364 10/23/2025 - Fixed supernova's bugged lighting - Fixed planetary night lights staying on during daytime - Unity security fix - Other bug fixes 0.363 10/22/2025 - Adjusted 3I/ATLAS (interstellar comet) trajectory parameters from new available data. - Improved shadows - Bug fixes 0.360 10/06/2025 - Improved stability update - Performance improvements for the n-body part of the simulation - The simulation now runs much more smoothly when you select the "accurate orbits" option in the physics settings; when you select that option moons in tight orbits won't get flung out anymore - Fixed "Seach" and "Replace by" functions - Bug fixes 0.353 09/09/2025 - Performance improvements for the n-body part of the simulation - The simulation now runs much more smoothly when you select the "accurate orbits" option in the physics settings; when you select that option moons in tight orbits won't get flung out anymore - Fixed "Seach" and "Replace by" functions - Bug fixes 0.352 08/06/2025 - Added a surface temperature option (from the textures menu p.7) for each planet. For Earth, it's activated by default. Earth will freeze when its cold, and its water will evaporate when its hot. - You can change the temperature texture settings using the sliders menu on the right 0.350 04/16/2025 - You can now add magnetospheres to planets using the textures menu. Stars produce stellar winds that deform the magnetospheres. - In the physics menu, you now have the option to prioritize simulation accuracy over speed. It will prevent objects getting flung out of orbit during time acceleration, but may cause extra lag. - Switched from Euler to leapfrog integration for the n-body calculations. It should result in more stable orbits. 0.346 03/27/2025 - Fixed Mars texture - Bug fixes 0.344 02/26/2025 - You now have an option to add objects using spherical coordinates (Right Ascension, Declination and Distance from selected origin). Spherical coordinates for any body can be found on Wikipedia among others. With this option you can add objects in their scientifically correct locations. To use it, press the sphere icon after clicking the "Add new body" button. - Bug fixes 0.343 02/12/2025 - You now have an option to add objects using spherical coordinates (Right Ascension, Declination and Distance from selected origin). Spherical coordinates for any body can be found on Wikipedia among others. With this option you can add objects in their scientifically correct locations. To use it, press the sphere icon after clicking the "Add new body" button. - Bug fixes 0.342 02/12/2025 - Added comet C/2024 G3, which has reached perihelion on January 15 and will be visible for some more time - Collision now don't make craters by default. If you want collision craters, you can switch the setting on in the physics menu. - Fixed star and brown dwarf collision bug - Fixed bugged moon night lights 0.341 01/18/2025 - You can now add customisable asteroid belts to any star. Please be aware that having a lot of particles in the simulation can cause extra lag. - Fixed bug where the orbital period would not be calculated anymore in the orbit helper - Fixed axial tilt and rotation period input bugs. - Particle ring bug fix. 0.338 12/26/2024 - You can now add customisable asteroid belts to any star. Please be aware that having a lot of particles in the simulation can cause extra lag. - Fixed bug where the orbital period would not be calculated anymore in the orbit helper - Fixed axial tilt and rotation period input bugs. 0.337 12/23/2024 - The asteroid belt is now better looking and customisable. In a future update you will be able to add asteroid belts to any star - Fixed visual bug when looking at a planet with an atmosphere through another atmosphere - The HD texture pack now includes removal of all Ads - Fixed CJK glyph style bugs 0.335 12/15/2024 - The orbit helper will now give an indication of the orbital period of the selected object. - You can now also enter axial tilt and rotation period directly by clicking on the value instead of using the control buttons - Added a fictional alien HD planet. To get it, (re)download the free DLC pack. - Performance fixes - Bug fixes 0.330 11/30/2024 - Added a fictional alien HD planet. To get it, (re)download the free DLC pack. - Performance fixes - Bug fixes 0.327 11/15/2024 - Added extra skybox to the free DLC pack: Hubble Deep Field background - You can now create binary planets (barycentre outside of their volume) that can orbit another object. - Bug fixes 0.322 11/02/2024 - Added an interactive tutorial that explains basic functions. It activates automatically on first open op the app, but you can also start it in the Help menu (from the main menu). - Bug fixes 0.320 10/25/2024 - Added 3 spaceship models as free DLC - Rearranged menus - Fixed spaceship control mode - UI and collision bug fixes 0.317 10/17/2024 - Added 3 spaceship models as free DLC - Rearranged menus - Fixed spaceship control mode - Bug fixes 0.314 10/12/2024 - Added 3 high-res texture and terrain maps for Earth, Moon, and Mars as a new DLC option. I can't include them with the game due to size limitations. A small fee is required to download them, to help with server hosting and development costs. Thanks for your support! - You can now move around freely on planet surfaces - Fixed brown dwarf and procedural planet texture bugs 0.313 10/04/2024 - Added three high-res texture and terrain maps for Earth, Moon, and Mars as a new DLC option. These maps are optimized for mobile devices and are downloadable as DLC due to app size limitations. A small fee is required if you want them, to help with server hosting and development costs. Thanks for your support! - You can now move around freely on planet surfaces - Various bug fixes and improvements 0.311 10/02/2024 - You can now move around freely on a planet's surface when "landed" - Added a new customisation feature: you can now flatten any object in the direction of your choice (for example, to create a "Flat Earth"). You can find it in the sliders menu. - Bug fixes 0.310 09/28/2024 - Added a new customisation feature: you can now flatten any object in the direction of your choice (for example, to create a "Flat Earth"). You can find it in the sliders menu. - I realised some people prefer the classic black hole accretion disk so you can now switch between the classic accretion disk and the particle accretion disk in the accretion disk panel. - Bug fixes 0.307 09/25/2024
