CloudLabs Star constellation vs ORBITARIUM

In this practice, you need to calculate the perimeter of an irregular polygon in order to determine the perimeter projected by the constellations as seen from our perspective on Earth in order to build a holographic projection room. The simulator recreates an observatory with a computer and the required instrumentation you need to observe the constellations.

ORBITARIUM is a native astronomy app for iPhone and iPad that lets you explore the Solar System now through interactive 3D graphics and on-device astronomical calculations. Move through time and see planetary positions, day and night on Earth, axial-tilt seasons, and lunar phases update together in one coherent view. KEY FEATURES • The Sun, all eight planets, and the Moon in an interactive RealityKit scene • Drag, pinch, and tap to orbit, zoom, and focus on celestial bodies • Select a date, play or pause time, change speed, and move across a four-year range • Earth's day-night boundary, city lights, clouds, and atmosphere synchronized with sunlight • Northern and Southern Hemisphere seasons explained through axial tilt • Moon phase, illumination, age, and the next principal phase • Local time, solar altitude and azimuth, sunrise, and sunset for nine locations worldwide • Japanese and English localization • No account required; core features work completely offline Planet positions and astronomical events are calculated on device. Body sizes and distances are compressed or exaggerated for educational readability and are clearly identified in the app.
