The various planets are thought to have formed from the solar nebula, the disc-shaped cloud of gas and dust left over from the Sun's formation. The currently accepted method by which the planets formed is accretion, in which the planets began as dust grains in orbit around the central protostar.

Through direct contact and self-organization, these grains formed into clumps up to 200 m (660 ft) in diameter, which in turn collided to form larger bodies (planetesimals) of ~10 km (6.2 mi) in size.

These gradually increased through further collisions, growing at the rate of centimetres per year over the course of the next few million years.

    Does not look close to a simulation, or interactive. cool looking though.
