Solar System Scope models the Solar System, night sky and outer space, showing object positions alongside related facts. Its 3D encyclopedia covers planets, dwarf planets and major moons with visualizations. The night-sky view can show stars and constellations from a chosen location on Earth and simulate skies from past or future times; the mobile version also lets users point a device toward the sky to find celestial objects. The maker says its calculations use NASA-published orbital parameters, and its planet and moon maps use NASA elevation and imagery data, with colors tuned against spacecraft and Hubble imagery. The Android encyclopedia is available in 19 languages. Solar System Scope runs on Android, iOS, macOS, web and Windows. The online version is free, as are mobile apps with optional in-app purchases. The Windows and Mac desktop app costs $9.80, paid once and includes fullscreen and offline modes. The maker also provides embed code for websites and textures for image viewing or 3D rendering.
