Jan 2, 2021 Replies: 3 Very very rough (and code not optimized at all)....planets in orbit around the sun: 1. Assumed all orbits are circular 2. Have not scaled the orbits (else I will run out of UI space) 3. Have not scaled the sun and the planets 4. When starting all planets will be aligned "due south" 5. Every "tick" event of the timer moves the planets by the angle that they will move in 24 hours (based on the approx number of days for each planet to orbit 360 degrees around the sun) I have added "Pluto" as well (9th "rock" from the sun") It gives a fair idea of how the planets move around the sun relative to one another.....

Johan Schoeman Expert Licensed User Longtime User Jan 3, 2021 #4 An improvement - the planets' starting positions are as what they should be (more or less - from literature) on 1 January 2021. Every tick of the timer then represents 24 hours and the planet positions are updated accordingly. The label (top left) indicates the change in date as what the timer ticks. Change the timer's tick "time" to speed it up or slow it down (a tick represents 24 hours) The calculation of planet positions are far better than that of the project in post #1 Attachments 1609677824639.png 238.9 KB · Views: 612 TurtelPlanets.zip TurtelPlanets.zip 70.5 KB · Views: 516
