Solar System Scope is an astronomy model and app for exploring the Solar System, night sky, and outer space, with celestial positions and related information. Its 3D encyclopedia covers planets, dwarf planets, major moons, and other objects. The night-sky view shows stars and constellations for a location on Earth and can simulate earlier or future skies; mobile users can point a device at the sky to find objects. The maker says calculations use NASA-published orbital parameters, while planet and moon maps use NASA elevation and imagery data, with colors tuned using spacecraft and Hubble imagery. The Android encyclopedia is available in 19 languages. Solar System Scope runs on Android, iOS, macOS, web, and Windows. The browser version and mobile apps are free, with optional in-app purchases on mobile. The Windows and Mac desktop app costs 9.80 USD per once and includes fullscreen and offline modes. The maker also offers website embedding code and planetary textures.
Who it is for
It suits learners and astronomy enthusiasts who want to explore celestial objects, view skies for different times, or practice identifying objects on mobile. Teachers or site owners may also find the embedding code useful.

Solar System Scope: the full review
Solar System Scope offers several ways to explore the sky, from a browser model to mobile sky viewing and an offline desktop app. The free options cover online and mobile use, while the desktop app is a one-time purchase.
Solar System Scope suits curious learners and casual sky-watchers who want one tool for exploring planets and identifying objects overhead. Its strongest case is the range of free browser and mobile views; offline desktop use costs $9.80 once.
Overview
The product combines a real-time Solar System model, a night-sky view and reference material about celestial objects. That breadth makes it a useful starting point for moving between planetary systems and the sky seen from Earth, though it is a less obvious fit for people seeking a narrowly specialized astronomy tool.
INOVE develops Solar System Scope; its About page describes the team as mostly from an EU software company. The privacy policy says the service may collect personal, usage and location data. It names Google Analytics, Firebase and Unity Analytics, as well as Google and Unity advertising services. Payment card details go directly to third-party processors and are not stored or collected by INOVE. The policy also says absolute data security cannot be guaranteed, worth bearing in mind when using location-based sky viewing.
Key features
Explore planets and moons
The 3D encyclopedia covers planets, dwarf planets, major moons and more. Realistic visualizations give learners a way to explore celestial bodies visually rather than relying only on written reference material. Planetary and lunar maps draw on NASA elevation and imagery data, with colors tuned using spacecraft and Hubble imagery.
See the sky from Earth
The night-sky view shows stars and constellations for a location on Earth and can simulate skies from the past or future. On mobile, pointing the device at the sky helps identify constellations and celestial objects. That makes the app particularly useful for casual observation; the location-aware feature may be less appealing to people who prefer not to share location data.
Time and orbital context
INOVE says its celestial calculations use orbital parameters published by NASA and can show positions at any time. This supports exploration of how positions change, rather than limiting the model to a single present-day view. The maker also offers space and planetary textures for 3D rendering or image viewing, and iframe code for embedding the model on a website, at a minimum resolution of 500 by 400 pixels.
Pricing
Solar System Scope is freemium, with free online and mobile editions and a one-time desktop purchase. The lower-cost options are enough for browser exploration or mobile sky viewing, but offline access and fullscreen use are reserved for the desktop app.
| Plan | Price | What it includes |
|---|---|---|
| Free online version | 0.00 USD per free | Runs in a desktop browser with WebGL; listed browser versions include Chrome 57, Firefox 52 and Safari 10.1. |
| Mobile Version | 0.00 USD per free | Android and iOS, with optional in-app purchases. |
| Desktop App | 9.80 USD per once | Windows and Mac, fullscreen and offline mode; 300 MB free disk space minimum. |
The desktop app’s one-time price makes it the clearest choice for users who need offline access rather than an ongoing subscription. Its minimum requirements are Windows 7, Windows 8.1, Windows 10 or Mac OS X, with 2 GB RAM. The mobile edition remains free to start, but optional in-app purchases mean it is not an entirely purchase-free offering.
Platforms
Solar System Scope is available on Android, iOS, macOS, the web and Windows. The online version needs a desktop browser with WebGL, while the desktop app supports offline use. Android’s encyclopedia is available in 19 languages, giving it broader language coverage for learners using that edition.
Who it's for
Choose Solar System Scope if you want a visual introduction to the Solar System alongside a way to explore stars and constellations from a location on Earth. Its web and mobile free options suit casual exploration, while the paid desktop edition serves users who value fullscreen viewing and offline access. It is less suited to users who want to avoid location data collection or need a tool focused on a specialized observing workflow.
Pros and cons
- Pro: Planet, moon and night-sky views sit in one product, so learners can move between Solar System objects and the sky from Earth.
- Pro: Past and future sky simulation and orbital positions at any time support exploration beyond a static snapshot.
- Pro: A free browser option and free mobile edition lower the barrier to trying it; desktop offline use is a one-time $9.80 purchase.
- Con: Mobile includes optional in-app purchases, so not every part of that edition is necessarily free.
- Con: The privacy policy permits collection of personal, usage and location data and names analytics and advertising services, a concern for privacy-conscious users.
Alternatives
Browse astronomy apps to compare more tools. Choose NASA Eyes if you want a free browser-based option and do not need offline access; it requires an internet connection. Cosmic Watch is another freemium choice on Android, iOS and macOS, with a free tier covering sky, Earth and Solar System views, a sky guide, layers, star names, world clock and notifications.
Night Sky is a freemium alternative for Android, iOS and macOS. Star Chart is available on Android, iOS, macOS and Windows, and its free plan includes every feature and upgrade without subscriptions or paywalls, with optional star sponsorship. Seestar App is a free alternative for Android, iOS, macOS and Windows.
Luminos Pro is a freemium option for iOS and macOS with a free trial and paid plans. UNISTELLAR App is a free alternative for Android and iOS, while Gaia Sky is free on Windows, macOS and Linux.
Verdict
Solar System Scope is a strong fit for learners and casual sky-watchers who want planet exploration and location-based sky viewing in one product. Its main advantage is the breadth of free web and mobile use, with an offline desktop app available for a single $9.80 payment. Look elsewhere if you need to avoid location-data collection or want a tool centered on a more specialized astronomy use.
