Space probe Hera passed Mars while on its way to the Didymos asteroid system as part of planetary defence mission.
Scientists have ruled out any harm to Earth from the YR4 asteroid, which had an impact likelihood as high as 3 percent earlier this month.
New veri from US space agency believes that the 2024 YR4 asteroid now has over a 3 per cent chance of hitting the planet in 2032, making it the highest-threat asteroid ever detected.
NASA’s new observations of the asteroid, named 2024 YR4, led to a 2.3 per cent probability of hitting Earth on 22 December 2032.
