Installation, Usage & Compatibility
Getting Solar Walk up and running is straightforward. Open the App Store on your iPhone, iPad, or Mac, search for “Solar Walk – 3D Solar System Model,” and tap “Get.” The download size is roughly 150 MB, and the app requires iOS 13.0 or later, iPadOS 13.0 or later, and macOS 10.15 (Catalina) or newer. For Android users, the app is also available on the Google Play Store with comparable system requirements (Android 8.0 Oreo or later). Once installed, launch the app and grant permission to access your device’s motion sensors—this enables the intuitive tilt‑to‑navigate feature on mobile devices.
When you first open Solar Walk, you’ll see a simplified view of the Sun at the center of the screen. Use a two‑finger pinch gesture to zoom out and reveal the planetary orbits. Swiping left or right rotates the system, while a single tap on any planet opens a fact sheet containing size, mass, orbital period, composition, and recent mission highlights. The navigation bar at the bottom provides quick shortcuts to the Earth globe, galaxy view, and the educational video library.
On macOS, navigation relies on the trackpad or mouse: scroll to zoom, click‑and‑drag to rotate, and double‑click a body for detailed information. Keyboard shortcuts are also available (e.g., ⌘ + ←/→ to cycle through planets). The app automatically detects the device orientation and adjusts the UI for portrait or landscape mode, ensuring a seamless experience whether you’re using an iPhone in your pocket or a 27‑inch iMac on a desk.
