Just watch the planets and if you want some more fun press space. Tell me if the planets line up with a picture to prove.
I just had the idea to make a solar system to rotational speed but x 100. The calculations were simple take the number of (earth) days for a year, divide 1 by the number of days in a year for the planet you want to calculate then multiply the outcome by 100 but you can also try different speed feel free to experiment. Isn't the best and Saturn looks like an egg, sorry. You might see some buffering with Neptune this is because there are too many clones for scratch to uphold. I will add moons in the next version. Heart and Star please
