Newly Discovered Asteroid to Make Close Pass by Earth

The Apollo-class asteroid is estimated at 50 to 115 feet wide and will offer astronomers a rare close-range observation opportunity.

  • On Monday, May 18, newly discovered asteroid 2026 JH2 will safely pass Earth at about 56,000 miles, with NASA's Jet Propulsion Laboratory classifying it as an Apollo-class near-Earth object posing no collision risk.
  • Astronomers at the Mount Lemmon Survey in Arizona and Farpoint Observatory in Kansas recently discovered 2026 JH2, noting that such small asteroids are notoriously difficult to track due to limited light reflection.
  • Scientists estimate the asteroid measures between 50 and 115 feet, comparable to the object behind Russia's 2013 Chelyabinsk airburst, and will pass within 24% of the average lunar distance.
  • The Virtual Telescope Project will broadcast the flyby live online at 21:45 UTC on May 18, while amateur astronomers may observe the asteroid through modest telescopes as it brightens before closest approach.
  • This flyby precedes the 2029 encounter with near-Earth asteroid Apophis, which will pass just 20,000 miles from Earth as improved observation capabilities continue expanding the database of smaller bodies.
