Planetarium 3D vs Celestial Simulation

Planetarium 3D turns the solar system into a place you can actually move through. Spin the system with your fingers, zoom in, tap a world, and launch across space to meet it. Drift past Saturn's rings, drop in on Jupiter's moons, or head far beyond Pluto to explore dwarf planets and distant icy worlds. Choose how you want to travel: - Tap any planet to fly there instantly - Visit moons directly and open fact cards along the way - Explore dwarf planets and named asteroids beyond the main planetary lineup - Launch cinematic tours with different flight styles and perspectives - Capture and share your favorite views This version lets you explore more than the classic solar system view. Alongside the 9 planets and 23 moons (now with Mimas, Iapetus, Miranda), you can now travel to worlds like Ceres, Vesta, Pallas, Haumea, Makemake, Eris, Sedna and Quaoar. Built for curiosity, not complexity: - Beautiful 3D planets, rings, lighting and atmosphere effects - Real science-inspired facts and orbital data - Simple touch controls with quick onboarding - Supports iPhone, iPad, Mac and Apple TV - Available in 19 languages No account. No setup. Just open the app and start flying.

Celestial Simulation Experience the universe as it truly moves. Celestial Simulation is a high-fidelity, physics-based app that lets you explore and understand celestial motion through real simulations—not animations or guesses. Every event is driven by time, location, and real celestial mechanics. From eclipses and planetary motion to lunar occultations and chaotic three-body dynamics, the app turns complex astronomy into intuitive, visual experiences. Observer-Based Simulation Your location matters. Set your observing position on Earth and watch how celestial events change with latitude, longitude, and time. Every simulation adapts instantly to your chosen place and moment. Solar System Geometry Explore the mechanics of the inner solar system: - Annular and hybrid solar eclipses with umbra and antumbra geometry - Planetary conjunctions and minimum angular separations - Mercury and Venus elongations for optimal visibility - Retrograde motion visualized over days and weeks - Transits of Mercury and Venus across the solar disk Most simulations are continuous and time-accurate. Lunar Occultations See how the Moon moves through the sky: - Occultations of bright stars and planets - Local and global visibility bands - Geometry that explains why an event is visible from certain locations Three-Body Dynamics Go beyond classical orbits and explore real gravitational complexity: - Circular Restricted Three-Body Problem (CR3BP) - Lagrange points L1–L5 with stability insights - Chaotic motion in non-rotating frames - Extreme sensitivity to initial conditions - These simulations reveal how real spaceflight dynamics and celestial chaos work. Special Focus: Total Solar Eclipse 2026 (Europe) A total solar eclipse will cross Europe in 2026 — a rare and unforgettable event. Celestial Simulation lets you explore the full path of totality, simulate eclipse geometry from different locations, and understand how timing and position affect what you will see. Use the simulation to: - Compare observing locations across Europe - Visualize eclipse paths and shadow motion - Plan where and when to experience totality Whether you are preparing a journey or simply exploring the mechanics behind the event, the app helps you understand why the eclipse unfolds the way it does. Built for Exploration - Interactive time control - Clean, focused visualizations - Designed for learners, enthusiasts, and curious minds - No clutter, no gimmicks—just the universe in motion Celestial Simulation is a pocket laboratory for understanding how the sky actually works. Whether you’re learning, teaching, or simply fascinated by celestial mechanics, this app lets you see the physics behind the beauty.
