# Simon1994PlanetaryPositions

#### Simon1994PlanetaryPositions()
Core/Simon1994PlanetaryPositions.js 28

  Contains functions for finding the Cartesian coordinates of the sun and the moon in the Earth-centered inertial frame.

### Methods

#### staticCesium.Simon1994PlanetaryPositions.computeMoonPositionInEarthInertialFrame(julianDate, result) → Cartesian3
Core/Simon1994PlanetaryPositions.js 516

  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
