PlanetFun features:

• Solar system animation with configurable speed
• Set any local date and time
• Choose camera target (Sun, planets, etc)

• 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
