🚨 Close asteroid flyby today — but no danger to Earth! On May 18, 2026, building-sized asteroid 2026 JH2 will pass unusually close to our planet — at just 0.24 lunar distances, or about 90,000 km (56,000 mi) away. That’s closer than the Moon, but astronomers confirm there’s zero chance of impact. 2026 JH2 is estimated to be 15–34 meters wide — comparable in size to the Chelyabinsk meteor — and may brighten to magnitude 11.8 around its closest approach. You won’t see it with the naked eye, but observers with small telescopes may be able to catch it after sunset as it moves through Ursa Major and Leo. Don’t panic over scary headlines — this is a safe cosmic flyby and a rare chance to watch a near-Earth asteroid in real time. 🔭 Use the free Sky Tonight app to locate asteroid 2026 JH2 in your sky. #Asteroid# #2026JH2# #NearEarthAsteroid# #Astronomy# #StarWalk#
