Plot Synopsis

Hosted by TOP GEAR's Richard Hammond, HOW TO BUILD A PLANET interviews the world's top scientists and engineers and, starting with the raw materials of gas, dust, ice, and metal, uses interactive computer graphics to show step by step how a world, galaxy, and universe are put together. It's the ultimate engineering project and construction challenge: build a fully functioning planet in the night sky right above our heads, with experts like Michio Kaku explaining how he would build a sustainable planet around another star in our galaxy.
