Comet 67P/Churyumov Gerasimenko, imaged by the Rosetta spacecraft in August 2014. Rosetta is the first spacecraft to orbit a comet, it has been traveling for more than 10 years to reach 67P, which is currently between the orbits of Mars and Jupiter. Later this year Rosetta will deploy a lander named Philae to the surface of the comet to determine its composition. Observations of 67P will continue through its closest approach to the Sun in August 2015, revealing the changes that occur as it heats up.
