Beijing (CNS) – China's unmanned lunar probe the Chang'e 2 departed from the Sun-Earth L2 point on April 15 and is now en route to the asteroid 4179 Toutatis, according to Ouyang Ziyuan, an academician and senior advisor to the leading group of the Lunar Orbiting Exploration Project.
Ouyang made the remarks at a symposium held in Beijing on Wednesday to mark "World Space Week."
At 4.6 kilometers long and about 700 million kilometers from Earth, the Toutatis is a potentially hazardous object to the planet, he said. If a collision happened, it would produce the equivalent of one trillion tons of explosives, or 50 million Hiroshima atomic bombs, he added.
Ouyang also said that China's solar system exploration until 2030 would use the exploration of Mars as an entry point, followed by the sun, asteroids, Venus and Jupiter.
The Chang'e 2 was launched on October 1, 2010, entered orbit around L2 on August 25, 2011, and began transmitting data from its new position in September 2011.
