The planets are the stars of online documentary

It is an old story, more than 4.5 billion years old.

Eight celestial bodies, each with their own distinct personality, born together and battling the violence of our early solar system, vying for their own survival and thriving to become stable planets.

Geological epochs come and go, entire atmospheres are formed and lost, and the planets themselves even begin to alter course. Thanks to a new documentary made by BBC Studios' Natural History Unit, it's all vividly portrayed with groundbreaking special effects and computer-generated imagery more akin to that of big-budget sci-fi movies.
