The professor tells the history of Earth's neighbouring worlds, using the latest scientific research - Here's everything you need to know about the fascinating programme.
What is The Planets about?
In this major new landmark series for BBC Two co-produced by the Open University, Professor Brian Cox tells the extraordinary life story of our solar system.
Using the data from the very latest space explorations, groundbreaking CGI will reveal the unimaginable beauty and grandeur of each planet, and whether there really is life on other planets.
The Planets shares the spectacle and drama of 4.5 billion years of planetary history in stunning new detail.
The show will look at the development of the four rocky worlds closest to the Sun: Mercury, Venus, Earth and Mars.
Born together, they battled the unbelievable violence of the early solar system to become stable planets.
For a while each had a moment of hope when they enjoyed almost Earth-like conditions. Yet today Mercury is a scorched barren world, Venus is a runaway greenhouse world with a scorching atmosphere and Mars is a frozen desert.
Only on Earth do oceans - and life - survive.

What has Brian Cox said about The Planets?
Speaking to the , Brian said: "This is a much bolder series intellectually.
"Particularly things like the grand tack model, they've only been around a couple of years and it's unusual to put those cutting-edge theories into landmark television, you tend to be rather more conservative.
"The other difference is there's an underlying philosophy to the series. I like the Jupiter film, in particular, for this reason.
"The philosophy is that the solar system is a system but I think that's quite surprising, and an important point actually, because it is quite natural for us, I think, to focus our eyes on the Earth alone and think that we're isolated from the goings on in the rest of the Universe."
