8 ‘potentially hazardous asteroids’ near Earth discovered by NASA
Eight new asteroids that could pose a threat to Earth were spotted by NASA’s asteroid-hunter among 439 other objects rotating around our planet, according to a report newly released by the space agency.
NASA’s Near-Earth Object Wide-field Survey Explorer (NEOWISE) telescope, which made a comeback in 2013 after going into hibernation mode in 2011, has come up with a second year’s worth of survey data on Earth’s surroundings that was published in a report by NASA.
â€œEight of the objects discovered in the past year have been classified as potentially hazardous asteroids (PHAs), based on their size and how closely their orbits approach Earth,â€ the report goes.
In what NASA described as a â€œmilestoneâ€ mission, the telescope, which is tasked with detecting, tracking, and characterizing asteroids and comets, detected a total of 439 NEOs (near-Earth objects) in 2015, of which 72 were newly discovered.
