Intergalactic Education introduces Intergalactic Solar System, a mini-game that teaches about planets, moons, and countries. This space simulator lets you explore celestial bodies from the viewpoint of space itself. The latest edition adds the Milky Way as an observable galaxy. Intergalactic Solar System uses next generation science standards (Common Core aligned) astronomy and geography. (Follows standards ESS1.A, ESS1.B, and CCSS.ELA-LITERACY.RH.6-8.7) Try Intergalactic Solar System! Assess proficiency in Solar System knowledge according to educational standards. Rewarding levels of gameplay maintain engagement. You will forget you were doing astronomy and geography!

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.
