Rosetta is attempting to become first spacecraft to orbit and land on a comet. European Space Agency's 10-year mission has taken Rosetta billions of miles across solar system .

Alternatively, the comet’s orbit could be the handiwork of an as-yet-unseen planet whose mass lies somewhere between that of Earth’s moon and Mars, the researchers say.

Rosetta is the first satellite to orbit a comet, but it's not the first to study one close up. In 2004 NASA's Stardust spacecraft passed within a few hundred miles of the comet Wild 2.
