How do you know you'll get three moons? You know we once had 2 though.
Another idea! Just, re-tellling again, I know I said this but, what about Ctrl+Alt to fix to see the sky from an object. Then there appears a new UI it has << (backwards) < (backwards one frame) || (pause) > (Forward one frame) >> (Forward), and a lines and a clicable edit preferences. From there you can choose (when you click lines) when a do it to plot with a date of an object. Say you choose 7. A line traks the object in the sky, and places a dot labeled with the day. There is also another button, it says time. If you click it and enable it, there is a drop down menu, it says Day (it fixes on the Sun), Morning (it fixes the sun just below (or on) the horizon), Mignight (direectly opposite from the sun), Evening (it fixes sun below (or on) the horizon)
Oh, you can Ctrl+Shift click to focus on any object.
