Solar System 3D: Planets & Sky

CosmoNest is a 3D solar system and planetarium app for astronomy lovers: observe the Sun, the planets and the Moon up close, fly a spaceship between them, and find tonight’s real stars and constellations. Built from real space-mission and telescope data, it turns your phone into a calm window on space for students, families and stargazers. EXPLORE THE PLANETS IN 3D Pick a world on the solar system map to see its diameter, distance and length of year with a quick science fact. Start an observation to spin it with one finger and zoom with two; sharper surface detail loads as you get closer. Questions such as “Why is Mars red?” come with tips to see the answer on screen. • Sun: chromosphere and photosphere from solar-observatory ultraviolet data • Mercury: MESSENGER mosaic with terrain light and a crater atlas • Venus: Mariner 10 cloud patterns and a radar map of the hidden surface • Earth: day and night, clouds and city lights • Moon: NASA LRO colour map and LOLA elevation in its real phase • Mars: Viking mosaic and real 360° panoramas from the Curiosity and Perseverance landing sites • Jupiter and Saturn: Hubble maps, the Great Red Spot, the rings and a descent into the clouds • Uranus: the tilted blue giant and its ten main rings Neptune appears on the map with its key facts. NEW · FLY Take a spaceship through the solar system in first person. Set the speed with the lever, boost when the way is clear and watch your fuel. Come in too fast and you crash; get too close to the Sun and you burn up. Fly close to a world to observe it up close. NEW · TODAY’S ORBIT A new gravity puzzle every day: launch a probe from Earth, let the planets’ gravity bend its path and reach today’s target within five tries. Share your result as emoji, then practise freely. TONIGHT’S SKY See the real sky above you: 8,875 stars, the 88 constellations with lines and art, the Milky Way, the planets and the Moon. Let time flow, pick a dark, suburban or city sky, and tap anything to see where it is and when it rises and sets. Your approximate location stays on your phone. • A planet in the Moon’s place: hang Jupiter, Saturn or another planet where the Moon is, at its true size, and take a photo through the camera • Your light’s star: light that left Earth on your birthday is still travelling; see which star it has reached and get a reminder when it reaches the next • Night sky card: keep the sky of a day you love as an image A RECORD FOR EVERY WORLD Read each world’s record: its numbers, what standing there would be like, the missions that went, the story of its name, surprising facts, and a new fact every day. HOW ACCESS WORKS The Sun and the map are free. Every other world opens for 60 minutes with one rewarded ad, or for good with a one-time purchase; “All 10 worlds” opens all ten (Neptune and Pluto when they arrive) and removes every ad. Tonight’s sky, Fly and Today’s orbit are free the first time, then open with a rewarded ad; owning three planets removes those ads. Ads play only from a button that says what you get: no banners, no interstitials. Purchases restore with the same store account. DATA AND NOTICES Imagery and data come from public sources such as NASA, USGS, the Hubble OPAL program and the Hipparcos catalogue; see Data & Credits and Sources in the app. Some scenes are educational visualizations, not live footage or a measuring tool. CosmoNest is not an official app of NASA or any mission partner. Available in English, Korean, Japanese, Chinese (Simplified and Traditional), Spanish, German, French, Portuguese, Vietnamese and Indonesian, with original space ambience (starts muted) and a viewing mode with a timer.
