PlanetFun is a 4D solar system simulation (3D + time) Sun, planets, Moon and star positions are calculated using various astronomical methods. App source code (Delphi Firemonkey) is available at: https://github.com/omarreis/vsop2013 PlanetFun features: * Solar system animation with configurable speed * Set any local date and time * Choose camera target (Sun, planets, etc) * Configurable camera distance-to-target * Touch gestures: one finger pan, two finger zoom, two finger rotation * show planet orbits. Each orbit is represented by 52 dots (for Earth it is one dot per week) * Heliocentric axis (x and z) * VSOP2013 and VSOP87 planet position calculations * Moon positions calculations ELP2000 * Star background image with 42455 stars of the Hipparcos Input Catalogue * Star and constellation lines and names ( a celestial sphere image ) * Constellation drawings ( 31 constellations ) * actual 3D spheres for the 150 brightest stars * Lighthouse on Earth on your GPS position * phone in the scene is positioned according to phone sensors (Azimuth,Elevation,Roll) * click the phone button to enter augmented reality mode. * Almanac module allows exploring the ephemeris calculators (stars, planets, Sun, Moon, Earth) controls: * camera distance and angle of view. * planet scales * local time, time animation speed * control visibility of various interface elements * app uses sensors compass, gyro and GPS - requires permission This app collects no user data.

Key Features: - Real-Time Moon Rendering: Witness the moon's phases, liberations, and apogee/perigee with astonishing realism and accuracy. Use the intuitive time controller to seamlessly move forwards or backwards, witnessing the Moon's phases unfold continuously. Or, simply pick a specific date and time to jump to using the time picker. - High Realism and User-Friendly Interface: The Moon app is designed to provide the highest level of realism, ensuring accurate depictions of the moon's behavior while maintaining an intuitive and easy-to-navigate interface. - Yearly Moon Phase Calendar: Select any year to view a detailed list of significant moon phases (full, new, half), along with the precise date and time of each phase. Click on any event to jump to that specific time instance. Also, explore moon's maximum declination and apogee/perigee (maximum distances) effortlessly. - Earth Map with Moon Position: View the moon's current overhead position on the map. You can also select your location to see the parallactic angle of the moon phase, offering a unique perspective based on your geographic location.
