Rosetta comet mission: What is 67P? In 60 seconds

The European Space Agency made history in November by landing a probe on a comet 500 million km, external from Earth.

The robot probe Philae has since been hitching a lift on Comet 67P/Churyumov-Gerasimenko as it orbits the Sun.

Here is a quick look at the comet - and what it could teach us - in 60 seconds.
