Lutetia

Lutetia is an asteroid located in the asteroid belt between Mars and Jupiter. It is approximately 100 kilometers (62 miles) across and has a heavily cratered, irregular surface, indicating a long history of collisions. Lutetia's composition is mainly metal and rock, with some carbon-rich material, making it a valuable target for studying the early solar system. In 2010, the European Space Agency's Rosetta spacecraft flew by Lutetia, providing detailed images and data that help scientists understand its structure and history. Lutetia's study offers insights into the building blocks of planets and the processes shaping our solar system.
