Astronomy: Lunar (AL) v 0.1 Version 0.1 is a simple astronomy program showing orbital characteristics (circular simplified) using Turtle. It includes an animation of the light Comms delay to commemorate the anniversary of Apollo 11 in July. I am experienced, but this is my first Numworks script. There is a similar program by me on HP Prime. If your platform supports keyboard, change waittime to 0. (Numworks app has EXE key) https://www.hpmuseum.org/forum/thread-13311.html Tested on Numworks 19.4.0 Tested on Numworks 20 3.2
