Goals: Chang'e 2 orbiter was China's second lunar mission. Once it completed its science and engineering objectives in lunar obit, it was sent to orbit around Lagrangian point L2 about 1.5 million km away from Earth, where gravity from the sun and Earth balances the orbital motion of a satellite.

Accomplishments: Chang'e 2 arrived at L2 as planned. China is now the world's third country or organization to successfully put a spacecraft into orbit around L2, after the European Space Agency (ESA) and NASA.
