COSMOS is a solar system you hold in your hand. This is not a decoration. Every planet sits exactly where it is right now, computed from real orbital mechanics. Where is Jupiter tonight? How are Saturn's rings tilted? Open the app — the answer is there. - REAL ORBITS Positions of all 8 planets and the Moon are computed from Keplerian orbital elements in real time. Scrub through time to see the sky 10 years from now — or the day you were born. - PHOTO-REAL TEXTURES Saturn's rings, Jupiter's Great Red Spot, sunspots and solar granulation — every texture is generated on your device and stays crisp as you zoom. - CONTROL TIME From one second = hours, to one second = years. Watch the Moon change phase and the planets trace their orbits with your own eyes. - EXPLORE FREELY Pinch and swipe from outside the solar system down to a planet's face. Tap any body for details. - DESIGNED WITH RESPECT - No ads, ever - No in-app purchases — one simple price - Works fully offline, on a plane or on a mountain - Collects zero personal data For curious kids asking "why?" For stargazers who want a quiet moment of awe. The real universe, in your pocket. LANGUAGES English, Japanese, Simplified Chinese, Korean, Spanish, French, German
