Rosetta space probe moves closer to 'rubber duck' comet
A plan to land on a icy comet in space will be more difficult than scientists previously thought.
The European Space Agency have released a video of the comet, nicknamed the space 'rubber duck' because of its shape.
Scientists didn't realise the surface of the icy object would be so uneven.
A probe called Rosetta will move closer to the comet in the next couple of weeks looking for a good place for a small robot to land later in the year.
