      A single class capable of drawing the solar system from Sun to Pluto (including 1500 asteroids). NEW: Retrograde planets/moons now possible, coloured labels, more comments in code, more accurate numbers, more real moons. You can easily add more or design your own solar system. . Thanks for inspiration, assistance and support to Peter Wilson whose upload 'A Simple Solar System Simulator, v1.0' http://www.planet-source-code.com/vb/scripts/ShowCode.asp?txtCodeId=47973&lngWId=1 inspired this. -------------NOTE--------------------------------- If it runs too slowly reduce the number of asteroids at Private Const AsteroidNumber As Long = 500 . I have run it with up to 5000 but the graphic is not that much different and very slow. ---------UPDATED-------------------------------------------Thanks to Peter Wilson who improved his zooming code and kindly sent it to me. Upgrade 1 notes: Added a new solar equator view, labels for planets and moons, improved collection based functionality, Asteroids do not display orbits (un-comment piece of code if you like that). All orbits are now eliptical and Pluto has its eccentric orbit . Planets have extra properties (oblate= Flat). ------------ CODERS this class automatically produces the labels it needs to operate without a seed control. Cute Trick extended on article in Computer Shopper Jun 2003.
