+++ As Seen on Reddit +++ Smash planets. Build solar systems. Rule the Milky Way. Milky Way: Cosmic Playground is the space sim where real physics meets pure sandbox fun - rated 4.7 stars by 2,500+ players. Every star, planet, moon, and meteor obeys genuine Newtonian gravity, and every collision runs on SPH simulation (smoothed particle hydrodynamics), the same math astrophysicists use. Nothing is scripted. Everything is yours to cause. Ever wondered what really happens when an asteroid hits Earth? Stop wondering. Trigger a meteor shower and watch meteors streak across the sky. Send a single meteorite down in slow motion and zoom in as it carves a glowing crater. Then scale up to a full asteroid impact and rewrite geology. This is your cosmic playground: no fail states, no waiting - just gravity, matter, and imagination. WHAT YOU CAN DO . Run a planet collision simulation with real SPH physics - worlds splash, shatter, and re-form differently every time . Rain meteor showers and asteroid impacts on Earth or any world you build . Grow planets from a spinning protoplanetary disk, like a true solar system simulator . Give any planet a ring system worthy of Saturn . Merge entire galaxies in 3D - stage the far-future collision of the Milky Way galaxy and Andromeda tonight . Spawn black holes and watch them feed, bending orbits and swallowing suns . Launch spacecraft and satellite constellations into orbits you designed yourself . Send comets sunward and watch their tails bloom (new Comet Tails update) . Go head-to-head in Planet Rivals mode . Sandbox freely as a space crash simulator, a planet simulator, and a gravity toy in one REAL SCIENCE UNDERNEATH Milky Way is a space simulation toolkit disguised as a game. Orbits, slingshots, tidal forces, and accretion emerge from real physics - not animations - so you absorb genuine astronomy just by playing. Kids see wonder. Students see their textbook come alive. Space lovers finally get a laboratory that fits in a pocket. ENDLESS EXPERIMENTS Build a double planet and test its stability. Find the exact asteroid size where "crater" becomes "extinction." Comb a debris field into rings. Rescue a doomed solar system using only gentle nudges. Then zoom out from a single cratered moon to two colliding galaxies you set in motion - few things on a phone feel this enormous. ALWAYS GROWING Major free updates ship constantly - the latest BIG UPDATE rebuilt the 3D Galaxy Merger, Comet Tails, and Planet Rivals. Rated 4+ for all ages. Download free and start rearranging the universe. The Milky Way took 13 billion years to form. See what you can do with it before your coffee cools.

Milky Way: Cosmic Playground version 0.5.16
Updated At: 2026-07-31
Changes: Version History Adding new galaxies to the 3D Galaxy Merger simulation 0.5.16 17h ago Introducing Meteoroid Breakup, where you can simulate how a meteoroid splits into smaller fragments as it enters Earth’s atmosphere. 0.5.15 4d ago Fixing the Sun’s intrinsic brightness in the 3D Milky Way map so you can see how bright the Sun would appear in the Proxima Centauri sky and around other nearby stars. 0.5.14 Jul 21 BIG UPDATE for the 3D Galaxy Merger, Comet Tails, and Planet Rivals games 0.5.13 Jul 16 Introducing Comet Tails, a tool for simulating the length and shape of comet dust tails. 0.5.12 Jul 14 Introducing 3D Milky Way Map where you can explore 3 million stars in our galaxy. 0.5.11 Jul 11 Milky Way Map PRO is included with your subscription and lets you explore the night sky at high zoom levels. 0.5.10 Jul 7 Introducing Milky Way Map, a photorealistic sky map 0.5.9 Jun 29 Reintroducing 2 free games: (1) Space Program and (2) Moon Landing 0.5.8 Jun 23 Introducing Merging Black Holes, where you can realistically simulate Geodesic ray-tracing black holes with Doppler and gravitational redshift, as well as a Volumetric accretion disk. 0.5.7 Jun 20 Introducing Giant Impact, where you can simulate the formation of the Moon. 0.5.6 Jun 11 Everyone can now test drive the “Giant-Impact Hypothesis” in the 3D SPH sandbox. Thanks for all the continued support from our early adopters. 0.5.5 Jun 6 Introducing a subscription that allows you to unlock all simulations for just $4.99 / month. Cancel at any time 0.5.4 Jun 4 Introducing Space Weather, where you can simulate the impact of a G5 (Extreme) geomagnetic storm.
Key Benefits
+ Interactive "what if" controls — you can manually dial up solar wind speed, density, and IMF Bz to simulate geomagnetic storms without waiting for the Sun to cooperate.
+ Live space weather data — pulls real-time solar wind measurements from NASA/NOAA every minute.
+ Physically accurate models — the magnetopause, bow shock, and aurora oval are calculated using real scientific equations, not artistic approximations. They are all rendered together, giving a complete picture of near-Earth space weather. 0.5.3 May 26 Improve UI/UX in 3D SPH Sandbox game
+ Drag-and-drop planet creation
