Contains functions for finding the Cartesian coordinates of the sun and the moon in the
Earth-centered inertial frame.
        
        
Methods
static Cesium.Simon1994PlanetaryPositions.computeMoonPositionInEarthInertialFrame(julianDate, result) → Cartesian3
    Computes the position of the Moon in the Earth-centered inertial frame
    
| Name | Type | Description | 
|---|---|---|
| julianDate | JulianDate | optional The time at which to compute the Sun's position, if not provided the current system time is used. | 
| result | Cartesian3 | optional The object onto which to store the result. | 
Returns:
    Calculated moon position
