    Parameters:
    
    pMillis - seconds since unix epoch
  - getMoonPositionOnEarth
```
public static Coordinate getMoonPositionOnEarth(long pMillis)
```
    Given a particular time (expressed in milliseconds since the unix epoch), compute position on the earth (lat, lon) such that the moon is directly overhead. Based on duffett-smith **2nd ed** section 61; combines some steps into single expressions to reduce the number of extra variables.
    Verified.
