Two asteroids may pass Earth by a narrow margin today, says NASA; Check size, speed and more
To discover, track and monitor asteroids, NASA has several tech marvels in place. The NEOWISE telescope, Atacama Large Millimeter/submillimeter Array (ALMA), Pans-STARRS1, and Catalina Sky Survey are some of the space and ground-based telescopes and satellites which the space agency uses. Since there is a historical precedent of asteroids impacting Earth and causing cataclysmic damage, it is imperative that we keep an eye on them for any potential impact scenarios. NASA has now revealed that two asteroids will pass Earth by a close margin today, April 4.
