The probe, which is now "in good conditions", reached the height at around 1 a.m. Sunday Beijing Time, the State Administration of Science, Technology and Industry for National Defence(SASTIND) said in a statement.

Chang'e-2 will be able to travel to a distance as far as 300 million km away from Earth, according to calculations done by scientists from the Beijing Aerospace Control Center.

Chang'e-2 was launched on Oct. 1, 2010 from Xichang Satellite Launch Center in southwest China and later orbited the moon to finish a more extensive probe than its predecessor Chang'e-1.

On June 9, 2011, after finishing its lunar objectives, Chang'e-2 left its lunar orbit for an extended mission to the Earth-Sun L2 Lagrangian point.
