NASA has discovered the 10,000th Near Earth Object (NEO) is about 1,000 feet (300 meters) wide asteroid named 2013 MZ5. NEO’s are asteroids and comets that approach the Earth. They will come within 28 million miles (45 million kilometers) of our planet during their orbit around the sun.
NASA Headquarters said that finding 10,000th near-Earth objects is a significant milestone. Many more to be found before they can be assured of any impact and do significant harm to Earth.They may be at least 10 times of this. 2013 MZ5 is not a hazardous asteroid and is not be any threat to Earth in future.
