Embark on an immersive journey through the solar system! Solar Explorer brings the solar system to life with a stunning 3D simulation based on real astronomical data, featuring 60+ celestial bodies and spacecraft. Experience the grandeur and mysteries of the universe in the palm of your hand. Key Features • Realistic Simulation – Explore the orbits of celestial bodies and spacecraft, along with the rotation of planets and moons, in an immersive 3D simulation. • Close-Up View – Observe surfaces and rotation up close, follow moons around their parent planets, and examine detailed 3D spacecraft models. • Landing View – View a realistic starry sky and the Milky Way from selected surface locations on different celestial bodies. • Time Acceleration – Speed up time or run it backward to explore how celestial bodies and spacecraft move. • Mission Replay – Replay selected space missions with trajectory overviews and close-ups of key events. • Surface Features – Zoom in to discover surface features and place names on the Moon, Mars, and other celestial bodies. Professional-Grade Experience • Planet, moon, and spacecraft positions are calculated using astronomical data and celestial mechanics, with information panel data updated to match the simulation time. • Inspect high-resolution surface textures up close and discover the varied landscapes of planets and moons. • Examine detailed 3D spacecraft models, including all five probes that have traveled beyond Neptune’s orbit, and track their speed and distance from Earth as simulation time changes. • Discover historic landing sites on the Moon, Mars, Venus, and other worlds, with details about landers and surface features. • Landing view uses celestial mechanics and viewing geometry to recreate the local sky and celestial motion, reflecting effects such as the Moon’s tidal locking and Venus’s retrograde rotation. • The Earth-Moon view extends to the Sun-Earth Lagrange points L1 and L2, with orbital paths for space telescopes such as JWST, Roman, and Euclid. • Enjoy detailed planetary rings, the Sun’s corona and glow, and sweeping views of the asteroid belt and Kuiper belt, along with shadows and transits. Intuitive Controls • Tap a celestial body or its name label to enter close-up view, or browse celestial bodies and spacecraft in the catalog. • Drag with one finger to rotate the view, and pinch with two fingers to zoom. • In close-up view, use the location picker to choose a landing viewpoint. On Earth, you can also use your current location. • Adjust the speed and direction of time in orbit view, close-up view, and landing view to observe rotation and orbital motion. Whether you’re an astronomy enthusiast, an educator, or a curious explorer, Solar Explorer opens a gateway to the mysteries of the universe. Download now and begin your space adventure!

Verdict
The clearest difference is review sentiment: Solar System by Clementoni at 100% against Solar Explorer 3D's 50%. Solar System by Clementoni also leads on monetization model (free vs free with in-app purchases) and iOS requirement (11.0 vs 16.0). Solar Explorer 3D's advantage is rating (4.2 vs 3.6) and update cadence (every 2 weeks vs every 24 months). On price, ads, in-app purchases and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Solar System by Clementoni sells 1 one-off in-app purchase and Solar Explorer 3D sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
Solar Explorer 3D holds the better App Store score, 4.2 against 3.6. That said, the two scores are not equally well evidenced: Solar Explorer 3D has 25 ratings behind it against 5, so its average is the more settled of the two. Written reviews complicate that: 100% of Solar System by Clementoni's written reviews are positive against 50% of Solar Explorer 3D's, so the app with the better star average is not the one people write more warmly about.
Solar System by Clementoni ships an update every 24 months, Solar Explorer 3D every 2 weeks. Both last shipped on October 24, 2026.
