Daily Near-Earth Object Close-Approach Report: June 11, 2026

Near-Earth object encounters catalogued across a 7-day window, reported on the UTC civil time scale.

On June 11, 2026 (UTC), daily screening of the NASA NeoWs catalogue resolves 39 near-Earth object close approaches across the report window. The single closest encounter is 2003 LN6, passing at approximately 3.68 lunar distances (1,417,040 km) with a relative velocity near 3.9 km/s. Its order-of-magnitude kinetic energy, for scale only, is near 0 Mt TNT equivalent; Astrophyzix can confirm that no listed object is on an impacting trajectory. There is currently no known impact threat reported.

Methodology

Close-approach geometry is taken from NASA NeoWs, which is fed by the Jet Propulsion Laboratory Solar System Dynamics small-body solutions that also underpin CNEOS. No local trajectory integration is performed; the report consumes NASA solutions directly to preserve the authoritative state. 

The Astrophyzix Dual-watch System can be accessed for real time, comprehensive data from JPL CAD and CNEOS Scout data. To open the console please click here - This system offers the highest level of real time astroid data available to the public. 

  • Source choice. NeoWs (api.nasa.gov) is used for this report: it carries the same underlying JPL small-body database. 
  • To view our live CAD and Scout Data in our official monitoring system please click here for the real time data. 
  • Time scale. NeoWs reports close-approach epochs on the UTC civil scale. For reference the BCRS dynamical offset is TT - UTC = 69.184 s for 2026 (37 leap seconds plus the 32.184 s TAI-to-TT constant).
  • Distance units. Miss distance is taken from NeoWs in astronomical units and lunar distances (1 au = 149,597,871 km, 1 LD = 384,400 km, IAU 2012).
  • Size estimate. Diameter uses the NeoWs estimated_diameter bracket (derived from absolute magnitude H with standard albedo bounds); the geometric mean is reported.
  • Energy context. Impact-energy figures are order-of-magnitude only: KE = 0.5 m v^2 with mass from the estimated diameter and an assumed bulk density of 2600 kg/m^3. They quantify scale, not risk - no listed object is on an impact trajectory.
  • Validation. Every record is range-checked (0 < dist ≤ 1 au; 0.05 ≤ v_rel ≤ 100 km/s; -5 ≤ H ≤ 40) and a diameter-from-H constant self-test runs each build. Result: PASS (H=22 -> 0.106-0.237 km); flagged records: 0.
