The asteroid will come relatively close to Earth by astronomical standards. ☄️
The PDCO is responsible for providing timely and accurate information to the government, the media, and the public on close approaches to Earth by potentially hazardous objects and any potential for impact," NASA says."If any PHO is found to pose a significant chance of impacting Earth , the PDCO will provide for NASA to send to the Executive Office of the President, the U.S. Congress, and other government departments and agencies.
NASA considers any NEO coming within 30 million miles of Earth's orbit as a potential hazard, but it is most concerned about those objects that cross Earth's orbit within one LD, which is close enough to potentially hit the planet. "Currently, an asteroid impact is the only natural disaster we might be able to prevent," NASA says."There are a few methods that NASA is studying to deflect an asteroid on a course to impact Earth." mission, which will send a spacecraft on a collision course with the asteroid system Didymos later this year."DART’s target is a binary asteroid system where one football-stadium-sized asteroid is orbiting a half-mile-wide asteroid ," NASA said.
While it might seem like NASA is trying to blow up the asteroid, that isn't necessary to be an effective planetary defense. "After all," NASA explains,"we’d only need to nudge an asteroid’s orbit enough to make it either seven minutes early or seven minutes late in its intersection with Earth’s orbit. It takes seven minutes for the Earth to travel the distance of its diameter, so if an asteroid arrives seven minutes early or late—it’ll miss us completely.
