China's state-run news service Xinhua reports that the nation's deep-space probe Chang'e-2 has successfully conducted a flyby of the asteroid Toutatis, at a distance of about 4.3 million miles (7 million kilometers) away from Earth.
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 6.2 million miles (10 million km) away from Earth in January next year.

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

In related news, scientists working with NASA's 230-foot-wide (70-meter) Deep Space Network antenna at Goldstone, Calif., have generated a series of radar data images of the three-mile-long (4.8-kilometer) Toutatis that made its closest approach to Earth on Dec. 12, 2012.
