Tokyo (CNN)A Japanese spacecraft has reached a diamond-shaped asteroid three years after setting off on its mission to learn about the origins of Earth.
The Hayabusa2 spacecraft arrived Wednesday at the asteroid Ryugu after leaving on a 300 million-kilometer (186.4 million-mile) journey from Earth that began in December 2014, the Japan Aerospace Exploration Agency said.
The spacecraft is roughly 20 kilometers (12.4 miles) from the asteroid, from where it will launch a projectile into the rock in a bid to excavate samples from beneath the surface.
