Close Flyby Details
On May 18 2026 at 5:23 p.m. EDT (21:23 UTC) the Apollo-type near-Earth object 2026 JH2 will skim Earth at a minimum distance of roughly 56,000 miles (? 91,000 km), about 24 % of the average Earth-Moon separation. Relative to Earth it will travel at ? 19,400 mph (31,200 km/h). The asteroid’s predicted brightness will peak near magnitude 11.5, well below naked-eye visibility but reachable with modest telescopes.
Discovery, Size, and Orbital Classification
2026 JH2 was first detected by the Mount Lemmon Survey (part of the Catalina Sky Survey) on May 9-10 2026, with follow-up observations from Farpoint Observatory and other sites. Size estimates range from 16 m to 35 m (? 50-115 ft), reflecting uncertainties in albedo and limited observation arcs. Its orbit places it in the Apollo class: a semi-major axis > 1 AU and a perihelion < 1.017 AU, meaning its path crosses Earth’s orbit.
Public Viewing and Live Coverage
The Virtual Telescope Project, led by astronomer Gianluca Masi, will stream a live feed from its Manciano, Italy facility beginning at 3:45 p.m. EDT (19:45 GMT). The asteroid will appear as a moving dot against the star field, reaching magnitude 11.5-11.8. European observers will have the best sky conditions; in the United States the object will be daylight-lit and therefore difficult to see without a telescope.
Official Statements & Responses
NASA’s Center for Near-Earth Object Studies (CNEOS) confirms that current orbital calculations show zero impact risk for 2026 JH2. ESA’s Near-Earth Object Coordination Centre echoes this assessment, noting the flyby is “well outside any hazard zone.” The Virtual Telescope Project adds that its advanced tracking will keep the asteroid in view throughout its closest approach. All agencies stress that objects under 140 m are not classified as globally hazardous.
Criticism & Opposition
Some commentators argue that the asteroid’s discovery only days before closest approach highlights gaps in early-detection capability. The New Scientist-style coverage cited “hyperbolic terms like ‘grazing’” as potentially overstating risk, prompting calls for clearer public communication about NEO monitoring limits.
Conflicting Reports & Gaps
- Size: Sources list 16-35 m, 33 m, and an outlier of up to 250 ft.
- Distance: Reported closest approaches vary between 56,000 mi (91,135 km) and 56,628 mi (91,600 km).
- Brightness: Peak magnitude quoted as 11.5 in some outlets and 11.8 in others.
- Observations: The asteroid has been tracked 24 times according to some reports, while others note “limited observations” without a precise count.
Verbatim Quotes
- “At the time of the observation, the object will be moving pretty fast against the stars, but our advanced telescopes will precisely track 2026 JH2 while it will be almost at its minimum distance from us, peaking in brightness, around magnitude 11.5, before it will set below our horizon,” — Gianluca Masi, Virtual Telescope Project founder
- “This is much closer than the moon, but about twice as far as GPS satellites,” — Carson Fuls, Director, Catalina Sky Survey
- “These asteroids have an orbit that is larger than Earth's orbit around the Sun and their path crosses Earth's orbit,” — NASA spokesperson
- “In astronomical terms, it’s as close as you can get without hitting,” — Mark Norris, University of Lancashire
- “ ‘It’s the kind of thing that would ruin a city quite efficiently, if it hit,’ Mark Norris, from the University of Lancashire, told New Scientist.” — Mark Norris, University of Lancashire
What’s Next
After 2026 JH2, asteroid 2026 JH1 will pass at 3.68 million mi on May 15, and the larger Apollo asteroid 99942 Apophis will approach within 20,000 mi on April 13 2029. Ongoing planetary-defense projects such as NASA’s DART mission and international tracking networks aim to improve early-warning times for future close encounters.
