Scientists find asteroids throw debris at their own Moons

NASA/Johns Hopkins APL/Steve Gribben Around 15 percent of near-Earth asteroids have small moons, which suggests binary systems are fairly common. Many of the larger asteroid pairs have likely formed ...

NASA demonstrates humanity may be able to stop an Earth-bound asteroid

The pair, millions of miles away, continues to pose no danger to Earth, and scientists say it will remain safely distant for at least the next century. But the experiment has already delivered ...
