Lutetia

[skipwords]Asteroid 2005 YU55 isn’t the only space flyer to make recent headlines. A new study reports that “the oddball asteroid Lutetia is a rocky remnant of the material that formed Earth, Venus and Mercury about 4.5 billion years ago.” Experts think Lutetia formed at the same time as the planets in our solar system, but that a collision with a young planet may have hindered its growth. Such a collision may have sent the space object spinning into the asteroid belt between Jupiter and Mars. It is imaged here as observed by the European Space Agency's Rosetta spacecraft, which flew past asteroid Lutetia on July 10, 2010.[skipwords]
