China's space probe Chang'e-2 has successfully conducted a maneuver in which it flew by the asteroid Toutatis, about seven million km away from the Earth.
Travelling in deep space, Chang'e-2 made the flyby on Dec. 13 at 16:30:09 Beijing Time (08:30"09 GMT), the State Administration of Science, Technology and Industry for National Defense (SASTIND) announced on Saturday.
The flyby was the first time an unmanned spacecraft launched from Earth has taken such a close viewing of the asteroid, named after a Celtic god.
It also made China the fourth country after the United States, the European Union and Japan to be able to examine an asteroid by spacecraft.
Chang'e-2 came as close as 3.2 km from Toutatis and took pictures of the asteroid at a relative velocity of 10.73 km per second, the SASTIND said in a statement. Sources with the administration told Xinhua that Chang'e-2 is continuing its deep space travel and will reach a distance of more than 10 million km away from Earth in January next year.

"The success of the extended missions also embodies that China now possesses spacecraft capable of interplanetary flight," said Wu Weiren, chief designer of China's lunar probe program.
Chang'e-2's extended missions, which were conducted millions of km away from Earth, have tested China's spacecraft tracking and control network, including two newly built measuring and control stations in the northwest Xinjiang Uygur Autonomous Region and northeast Heilongjiang province, according to the SASTIND.
