Blue-whale-sized asteroid to skim past Earth Monday — watch it live

A near-Earth asteroid called 2026 JH2, up to 115 feet (35 meters) wide, will pass about 56,000 miles from Earth on Monday, May 18, around 6 p.m. Eastern time—closer than many satellites. Discovered May 10 at Mount Lemmon Observatory, it orbits the Sun roughly every 3.7 years. It should reach about magnitude 11.5, making it visible with a decent telescope; a livestream from the Virtual Telescope Project will let viewers watch the flyby without special gear, and there is no chance of impact.
