Ephemeris Sky is a unique application that calculates realtime positions for objects in our solar system, demonstrating the incredible computing power of the iPhone/iPad.
Ephemeris Sky calculates the following values for each of the planets...
Current Altitude*
Current Azimuth*
Planet Rise Time*
Planet Set Time*
Rise Azimuth*
Set Azimuth*
Culmination*
Distance from Sun
Distance from Earth
Orbital Velocity
Ecliptic Longitude
Ecliptic Latitude
Heliocentric Longitude
Heliocentric Latitude
Distance (angular) from Perihelion
Distance (angular) from Aphelion
Planets Declination
Planets Right Ascension
Planet Phase
Apparent Magnitude
Angular Diameter
Axial Tilt To Orbit
*Requires Location Services to be enabled
The following clocks are also included…
Local Civil Time (LCT)
Coordinated Universal Time (UTC)
Local Sidereal Time (LST)
In addition to all the above, Ephemeris Sky allows you to view the planet positions graphically in a 2D representation. This lets you not only see the orientation of the planets in our solar system, but it allows you to quickly see which planets are in position for optimal viewing.
