/*
* ORRERY face
*
* The Orrery watch face is similar to the Astronomy watch face in that it
* calculates properties of the planets, but instead of calculating their
* positions in the sky, this watch face calculates their absolute locations
* in the solar system. This is only useful if you want to plot the planets
* on graph paper, but hey, you never know!
*
* The controls are identical to the Astronomy watch face: while the title
* screen (“Orrery”) is displayed, you can advance through the available
* planets with repeated short presses on the Alarm button. The available
* planets:
*
* ME - Mercury
* VE - Venus
* EA - Earth
* LU - Luna, the Earth’s moon
* MA - Mars
* JU - Jupiter
* SA - Saturn
* UR - Uranus
* NE - Neptune
*
* Note that the sun is not available in this menu, as the sun is always at
* (0,0,0) in this calculation.
*
* Long press on the Alarm button to calculate the planet’s location, and
* after a flashing “C” (for Calculating), you will be presented with the
* planet’s X coordinate in astronomical units. Short press Alarm to cycle
* through the X, Y and Z coordinates, and then long press Alarm to return
* to planet selection.
*
* The large numbers represent the whole number part, and the two smaller
* numbers (in the seconds place) represent the decimal portion. So if you
* see “SA X 736” and “SA Y -662”, you can read that as an X coordinate of
* 7.36 AU and a Y coordinate of -6.62 AU. You can literally draw a dot at
* (0, 0) to represent the sun, and a dot at (7.36, -6.62) to represent
* Saturn. (The Z coordinates tend to be pretty close to zero, as the
* planets largely orbit on a single plane, the ecliptic.)
