NASA's DART mission: What to know about the impact
Fox News
NASA will use its DART spacecraft to impact the faraway asteroid Dimorphos. The moonlet is nearly 7 million miles away from Earth and orbits Didymos.
The agency says the target asteroid, Dimorphos, is not a threat to Earth and the "perfect testing ground" to see if the asteroid deflection method would be a viable way to protect the planet should an asteroid on a collision course with Earth be discovered.
The small moonlet orbits a larger asteroid called Didymos, lapping it around every 11 hours and 55 minutes.
