Ten more moons have been confirmed to orbit around Jupiter, bringing the planet’s total known satellite count to 79. That’s the highest number of moons of any planet in the Solar System. And these newly discovered space rocks are giving astronomers insight as to why the Jupiter system looks like it does today.
The Japanese space agency has successfully rendezvoused with a diamond-shaped asteroid millions of miles from Earth. After travelling for three and a half years, the Hayabusa2 spacecraft made its final approach to the space rock on June 27 and is ready to start its exploration and survey of the asteroid. During its year-and-a-half mission, Hayabusa2 aims to land on the surface of the asteroid three times to collect samples that it can return to Earth in 2020.
