Description

Check out Periodycus! https://scratch.mit.edu/projects/107438426/ PLEASE ♥️ + ⭐️ and maybe even FOLLOW! Conquered lag! HAHAHA! My 8 best projects: https://scratch.mit.edu/studios/809574/ This is currently number 5. Other solar system projects: https://scratch.mit.edu/studios/1279054/ Inspired by Solar System Builder http://highered.mheducation.com/olcweb/cgi/pluginpop.cgi?it=swf::800::600::/sites/dl/free/0072482621/78780/Solar_Nav.swf::Solar+System+Builder Planet masses are nowhere near correct, sorry. The font is called "1979", for you font geeks. TIPS: Making lots of planets will cause the system to lag. It goes slightly slower when you are in the process of creating a planet. CHALLENGES: Make a moon around a planet. Create our solar system! Stabilize the first six planets.

Instructions

Create planets and watch the system evolve! T to turn on/off trails. C to clear R to reset the program Arrow keys to change what planet is being created Space to place a planet. PLACING A PLANET: Circular orbit: Just click to send the planet in a circle at the distance from the sun that the mouse currently is. Drag 'n' drop: Click once to set a starting position for the planet, then "pull" the mouse out from the planet to set its velocity. Let go to send the planet flying!
