Embark on an immersive journey through the solar system! Solar Explorer brings the solar system to life with a stunning 3D simulation based on real astronomical data, featuring 60+ celestial bodies and spacecraft. Experience the grandeur and mysteries of the universe in the palm of your hand. Key Features • Realistic Simulation – Explore the orbits of celestial bodies and spacecraft, along with the rotation of planets and moons, in an immersive 3D simulation. • Close-Up View – Observe surfaces and rotation up close, follow moons around their parent planets, and examine detailed 3D spacecraft models. • Landing View – View a realistic starry sky and the Milky Way from selected surface locations on different celestial bodies. • Time Acceleration – Speed up time or run it backward to explore how celestial bodies and spacecraft move. • Mission Replay – Replay selected space missions with trajectory overviews and close-ups of key events. • Surface Features – Zoom in to discover surface features and place names on the Moon, Mars, and other celestial bodies. Professional-Grade Experience • Planet, moon, and spacecraft positions are calculated using astronomical data and celestial mechanics, with information panel data updated to match the simulation time. • Inspect high-resolution surface textures up close and discover the varied landscapes of planets and moons. • Examine detailed 3D spacecraft models, including all five probes that have traveled beyond Neptune’s orbit, and track their speed and distance from Earth as simulation time changes. • Discover historic landing sites on the Moon, Mars, Venus, and other worlds, with details about landers and surface features. • Landing view uses celestial mechanics and viewing geometry to recreate the local sky and celestial motion, reflecting effects such as the Moon’s tidal locking and Venus’s retrograde rotation. • The Earth-Moon view extends to the Sun-Earth Lagrange points L1 and L2, with orbital paths for space telescopes such as JWST, Roman, and Euclid. • Enjoy detailed planetary rings, the Sun’s corona and glow, and sweeping views of the asteroid belt and Kuiper belt, along with shadows and transits. Intuitive Controls • Tap a celestial body or its name label to enter close-up view, or browse celestial bodies and spacecraft in the catalog. • Drag with one finger to rotate the view, and pinch with two fingers to zoom. • In close-up view, use the location picker to choose a landing viewpoint. On Earth, you can also use your current location. • Adjust the speed and direction of time in orbit view, close-up view, and landing view to observe rotation and orbital motion. Whether you’re an astronomy enthusiast, an educator, or a curious explorer, Solar Explorer opens a gateway to the mysteries of the universe. Download now and begin your space adventure!
