< >: change preprogrammed system x: create a random system a: turn autozoom on/off p: change perspective: Enter the number of the planet you want to be centered i: stats for nerds: Shows you the mass, velocity and relative position of each planet 1+9: unlock admin tools (if you want to save or restore a system)
Check out some of my other projects: Game of Life: https://scratch.mit.edu/projects/225972534/ Pacman: https://scratch.mit.edu/projects/214470124/ Mega Miner: https://scratch.mit.edu/projects/197035306/ Fractals: https://scratch.mit.edu/projects/110744757/ If you want to add or tweak planets it's really easy. If you take a look inside you'll find a script with some explanation you can use to do this yourself. I challenge you to make a perfectly balanced system with seven or more objects. (I gave up at 5) IF YOU WANT TO CREATE A COPY OF OUR SOLAR SYSTEM be sure to set variable G to 6,67259E-11 first. It's currently set to 1 because that makes it easier for me and others to create custom systems. This is NOT a model of our own solar system. Everything is off-scale and mass ratio's are unrealistic. This doesn't mean it's not functional. This is a mathematically correct model of a theoretical 2D star-planet-moon system without collison, and only uses the following equation: Fg=(G*m*M)/r^2
