INSTRUCTIONS: 1. Click the Green Flag 2. Press Space to enter into EXPLORE MODE. 3. Press Space again to change back to CALENDAR MODE. =================== >> EXPLORE MODE: - A special feature. Use the "month" and "date" sliders to calculate where the Earth's real position will be. >> CALENDAR MODE: - The default setting. It tracks a live-reading of where the Earth's real position is right now. ======================== This is a simple "Earth and Sun" orrery model. Most orreries include the Moon, but I couldn't figure out how to track the Moon's position around Earth's heliocentric orbit. If you know how I can add that in, please let me know in the comments. Thanks, :)
