Near-Earth Object (NEO) Close Approach Report
Observation Window: 20–23 March 2026
Executive Summary
During the monitoring period spanning 20–23 March 2026, a total of 25 Near-Earth Objects (NEOs) are recorded making close approaches to Earth within a range of 1.54 to 59.76 Lunar Distances (LD).
- Closest approach: 2026 FU at 1.54 LD
- Largest object: (2018 YU) at ~444 m diameter
- Highest velocity: 2022 SR2 at 24.33 km/s
- Potentially Hazardous Objects (PHAs): 2 identified
- Impact risk: None detected
All objects remain well within safe margins with no impact probabilities identified by current orbital solutions.
Key Observational Metrics
- Total Objects Tracked: 25
- Objects < 10 LD: 6
- Objects < 5 LD: 4
- Potentially Hazardous Objects (PHA):

Closest Approach Events (< 5 LD)
| Object | Date | Size (m) | Velocity (km/s) | Miss Distance |
|---|---|---|---|---|
| 2026 FU | 22 Mar 2026 | 13 | 4.40 | 1.54 LD |
| 2026 FS | 21 Mar 2026 | 37 | 15.43 | 2.11 LD |
| 2026 FD1 | 21 Mar 2026 | 8 | 4.50 | 2.71 LD |
| 2010 RA91 | 22 Mar 2026 | 82 | 9.89 | 4.67 LD |
Assessment:
These approaches remain well outside Earth’s gravitational capture influence. No orbital perturbations of concern are detected.
Mid-Range Approaches (5–20 LD)
- 2026 FK (6.90 LD)
- 2026 EE3 (10.13 LD)
- 2026 ER3 (18.27 LD)
- 2026 FQ1 (17.77 LD)
Assessment:
Routine flybys consistent with heliocentric orbital dynamics.
Distant Passes (> 20 LD)
- 2025 FR7 (26.22 LD)
- 2026 DH3 (26.97 LD)
- 2026 EM1 (36.95 LD)
- 2023 RJ3 (52.88 LD)
- (2018 YU) / 885377 (54.98 LD)
- 2017 RR15 (59.35 LD)
- 2009 VT (59.76 LD)
Assessment:
No measurable risk; included for catalog completeness.
Potentially Hazardous Objects (PHA) Analysis
2023 RJ3

- Velocity: 16.61 km/s
- Miss Distance: 52.88 LD
2017 RR15
- Diameter: ~312 m
- Velocity: 11.86 km/s
- Miss Distance: 59.35 LD
Assessment:
Both objects exceed size thresholds but remain far beyond hazard limits with no impact scenarios.
Velocity Distribution
- Lowest: 4.11 km/s
- Highest: 24.33 km/s
Size Distribution Overview
- Small (<20 m): 8
- Medium (20–100 m): 12
