Near-Earth Object Close-Approach Report: June 17, 2026

Near-Earth object encounters catalogued across a 7-day window, reported on the UTC civil time scale. NO IMPACT THREAT REPORTED 

On June 17, 2026,  screening of the NASA NeoWs catalogue resolves 37 near-Earth object close approaches across the report window. The single closest encounter reported by NASA NEOWS 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; no listed object is on an impacting trajectory. Screening of Live NASA JPL CAD shows only routine safe approaches. The next closest encounter reported by NASA CAD is 2026 LO1 at just over 14 lunar distances as shown below with five objects which are approaching shortly after.  A seven day outlook from NASA’s NeoWs is included for comprehensive coverage from both NASA data sets.

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.

Apollo NEO Condition Code 6 1‑Day Data Arc NO IMPACT RISK — See JPL Solution

Key Takeaways of Asteroid 2021 KN2

• NASA JPL Solution: Solution JPL 3 · Epoch 2461000.5 (2025‑Nov‑21.0 TDB) · SPK‑ID 54149826 · Producer: Otto Matic
• Orbit class: Apollo NEO — a = 1.4064 au, e = 0.3718, i = 3.77°, orbital period 609.23 days (1.67 years).
• Earth MOID: 0.001331 au (~199,000 km), placing the nominal orbit well inside the Earth–Moon system, but with no impact solutions in current JPL or CNEOS catalogues.
• Size estimate: Absolute magnitude H = 28.63 → approximate diameter ~5–12 m (albedo‑dependent), firmly in the small NEO regime.
• Rotation: Extremely fast rotation period of 0.021007 h (~75.6 seconds), based on LCDB data, suggesting a cohesive or monolithic body rather than a loose rubble pile.
• Orbit quality: Condition code 6, based on 65 observations over a 1‑day data arc (2021‑05‑30 to 2021‑05‑31), with a normalised RMS of 0.23451 — a short‑arc, moderately uncertain orbit.
• Recent close approach: On 2021‑05‑31, 2021 KN2 passed Earth at a nominal distance of 0.00097 au (~145,000 km) and the Moon at 0.00306 au, a close but non‑impacting flyby.
• Risk context: Not a Potentially Hazardous Asteroid — too small (H > 22) and no impact geometry in current solutions.
• Ignore clickbait and sensational claims about “mystery asteroids nearly hitting Earth” — the official data show 2021 KN2 as a small, well‑tracked, non‑hazardous NEO.

Confirmed Binary and Triple Near-Earth Asteroids

Introduction

Near-Earth asteroids (NEAs) are small rocky bodies whose orbits bring them close to Earth. Recent radar and optical observations have revealed that many of these objects exist not as solitary rocks but as binary or triple systems, where two or three bodies orbit one another. This article examines the confirmed cases of such systems, presenting only verified, peer-reviewed findings to provide an accurate, factual overview of their physical properties, orbital dynamics, and significance for planetary science.
