Astrophyzix Digital Observatory
Asteroid News, Research & Analysis

Astrophyzix.com is the publication of the Astrophyzix Observatory, offering unpaywalled, evidence‑driven analysis and real‑time monitoring of PHAs and NEOs. Our tracking consoles and reporting systems use and provide access to official NASA CNEOS Scout, JPL CAD, NeoWs, SBDB, Horizons and Sentry observational API datasets, peer‑reviewed sources, and high‑precision numerical methods and integrators (IEEE‑754 Float64, RKN4, Yoshida-4, Dormand-Prince, N-Body, DE441, Meeus, Verlet, DOPRI5, Schwarzschild GR Correction, Simon1994). Astrophyzix doesn't just display data, it performs live and 100% verifiable probabilistic orbital analysis. Designed for students, educators, researchers, and the public. Every console is uniquely designed and engineered by us. Astrophyzix is the counter‑argument to every paywalled, ad‑ridden, low‑quality “asteroid tracker” on the Internet. We are trusted by over 2 million users each month. Our research papers and technical notes can be accessed at astrophyzix.academia.edu. Original research and development literature is DOI registered with Zenodo and academically indexed by OpenAire. .

Asteroids Approaching Earth This Week: NEO PHA Close Approach Report 20-23 March 2026

Astrophyzix Digital Observatory

Near-Earth Object (NEO) Close Approach Report

Observation Window: 20–23 March 2026


NEO Close Approach Infographic

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):
    • 2023 RJ3
    • 2017 RR15

Closest Approach Events (< 5 LD)

Object Date Size (m) Velocity (km/s) Miss Distance
2026 FU22 Mar 2026134.401.54 LD
2026 FS21 Mar 20263715.432.11 LD
2026 FD121 Mar 202684.502.71 LD
2010 RA9122 Mar 2026829.894.67 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

  • Diameter: ~269 m
  • 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
  • Large (>100 m): 5

Risk Assessment

  • Impact Probability: 0
  • Trajectory Stability: High
  • Monitoring: Routine

Conclusion

The observation window represents nominal NEO activity. All recorded objects pose zero threat to Earth.
