Asteroid 1997 NC1 to skim past Earth at 6.7 lunar distances — live viewing planned
Asteroid (152637) 1997 NC1, a potentially hazardous Aten-class near-Earth object estimated at 0.75–1.65 km across, will pass Earth at about 6.67 lunar distances (0.017 AU) around 11:16 UTC on June 27, 2026—the closest approach since before 1600. It may reach roughly magnitude 10, making it observable with small telescopes under dark skies; the approach speed is about 8.9 km/s. Live viewing is planned via the Virtual Telescope Project starting at 23:00 UTC on June 26–27 as part of Asteroid Day 2026.
