A mostly scientifically-accurate representation of our inner Solar System, using real wold physics, where you can control the mass of the Sun and the speed of planets. Controls: - Space bar: Toggle the variables display, to see and change the mass of the Sun and the speed of planets. - 'P': Toggle the drawing mode, where planets leave a trail behind them.
The following data is accurate: - Planet's distance to the Sun (1AU = 100 pixels) - Mass of the Sun and planets, in kilograms - Orbital speeds of planets, in meters per second - Relative size of planets (for example, Mars is 0.53 Earths) What is not so accurate: - The size of objects relative to distances between them. If objects were to scale, all planets would be invisible, and the Sun would be just under a pixel wide. - The size of planets relative to the Sun. The Sun is much smaller than it should be. All data related to objects masses, sizes, speeds and distances to the Sun comes from Wikipedia.
