The European Space Agency’s Rosetta comet chasing spacecraft flew within 1,900 miles of the 83 mile wide Lutetia asteroid to obtain a close look at the mysterious object.
Scientists have been puzzled by the composition of Lutetia, which is named after the Latin name for Paris, since it was discovered 150 years ago.

They hope to be able to tell whether Lutetia, which is currently around more than 282 million miles from Earth, is either a primitive form of asteroid made of rock and carbon or a metallic one.
The information gleaned by Rosetta during its fleeting fly-by will provide scientists with new information about what giant asteroids are made of how the solar system formed.
