NASA has upgraded the impact risk for a massive asteroid recently discovered by Ukrainian observers that will pass close to the Earth in 2032, although a collision remains unlikely.
According to an update on NASA’s Near Earth Object Program site, the impact risk is now 1 in 9,090; up from 1 in 63,000 at the time the asteroid, identified as 2013 TV135, was discovered.
However, the updated figures still mean that the chance of the asteroid completing a safe flyby is 99.989 percent, slightly down from 99.992 percent in the original estimate.
The 400-meter-wide asteroid, discovered by an observatory in Ukraine’s Crimea earlier this month, is one of two asteroids to currently rank above zero on the 10-degree Torino Scale, which estimates asteroid impact hazards.
