Apophis 2029 Flyby Key Takeaways

  • No impact risk: NASA’s current orbital solutions for Apophis show zero impact probability for at least the next 100 years.[1]
  • The 2029 flyby: Using official NASA data, Astrophyzix can confirm that on Friday 13 April 2029, Apophis will pass at about 32,000 km above Earth’s surface (about 20,000 miles), closer than geostationary satellites but on a safe, non-impact trajectory.[1],[2]
  • Impact Risk removed: Astrophyzix can conform that high-precision radar observations in 2020–2021 allowed NASA to rule out all impact scenarios for 2029, 2036, and beyond within the 100‑year assessment window.[1],[3]
  • New Science opportunity: The upcoming 2029 encounter is now treated as a science scenario, not a hazard scenario. Astrophyzix Digital Observatory is looking forward to observing and studying this asteroid in 2029 during the flyby event.
  • A Benchmark object: Apophis is used as a reference case in planetary defence simulations, mission design studies, and public‑communication exercises.[4]

Author: Astrophyzix Digital Observatory — Evidence‑First Asteroid Report

326290 Akhenaten (1998 HE3) is a Potentially Hazardous Asteroid (PHA) belonging to the Aten-class of near‑Earth objects. Its orbit brings it extremely close to Earth’s orbital path, with a Minimum Orbit Intersection Distance (MOID) of just 0.00350906 au — approximately 525,000 km, slightly farther than the distance to the Moon. Despite this close geometry, current NASA/JPL orbital solutions show no impact risk for the foreseeable future.

Asteroid Overview

Asteroid 326290 Akhenaten was discovered on 21 April 1998 by R. A. Tucker at the Goodricke‑Pigott Observatory. It is named after the Egyptian pharaoh Akhenaten of the 18th Dynasty, known for attempting to shift Egypt toward monotheistic worship of the Aten — the visible surface of the Sun.

Akhenaten is classified as:

  • Aten asteroid — semi-major axis < 1 au
  • NEO — Near‑Earth Object
  • PHA — Potentially Hazardous Asteroid
  • SPK-ID: 20326290

The asteroid has been observed for over 33 years, giving it a Condition Code 0 — the highest possible confidence in its orbit.


Upcoming Close Approach of 326290 Akhenaten (1998 HE3)


Asteroid 326290 Akhenaten will make its next notable close approach to Earth on 2026‑May‑10. According to the latest JPL orbit solution (JPL 84), the asteroid will pass Earth at a nominal distance of 0.07355 au, which is approximately:

  • 11 million km
  • ~28.6 × the Earth–Moon distance

This encounter is classified as a safe, non‑hazardous flyby. The orbit is extremely well constrained, with a Condition Code of 0, meaning the uncertainty in the asteroid’s predicted position is effectively negligible.


Approach Velocity

During the 2026 flyby, Akhenaten will be traveling at a relative velocity of:

  • 10.81 km/s (relative to Earth)

This is typical for Aten‑class NEOs, which often have Earth‑crossing orbits and moderate encounter speeds.

A Potentially Hazardous Asteroid (PHA)  is a near-Earth object with an absolute magnitude of 22.0 or brighter (typically larger than ~140 metres) and a minimum orbit intersection distance (MOID) of 0.05 AU or less. This classification does not indicate an impact threat, but identifies objects that require precise orbital monitoring.

Asteroid (2026 GU) is an Amor-class near-Earth object (NEO) classified as a Potentially Hazardous Asteroid (PHA) based on its size and orbital proximity to Earth. The object was observed over a short 5-day arc in this week and its orbit is currently defined by the initial JPL solution (Solution 1 on 09 April 2026.) 


Despite its PHA classification, current orbital solutions indicate a relatively distant Earth flyby on 14 April 2026. Continued observations are required to refine its trajectory due to the limited observational baseline and elevated uncertainty level.

Key Takeaways


  • Close approach on 2026-Apr-14 at ~0.09884 AU.
  • Equivalent to approximately 38.4 lunar distances (~14.8 million km).
  • Classified as a Potentially Hazardous Asteroid (PHA).
  • Estimated diameter: ~150–300 meters (based on H magnitude).
  • Orbit currently constrained using 90 observations over 5 days.
  • Condition code 8 indicates high orbital uncertainty.
  • No impact threat identified.

What is a Potentially Hazardous Asteroid? 


A Potentially Hazardous Asteroid (PHA)  is a near-Earth object with an absolute magnitude of 22.0 or brighter (typically larger than ~140 metres) and a minimum orbit intersection distance (MOID) of 0.05 AU or less. This classification does not indicate an impact threat, but identifies objects that require precise orbital monitoring.


Close Approach Event — 27 March 2026


Asteroid 837253 (2013 FW13) undergoes a monitored Earth flyby on 27 March 2026 at approximately 02:27 UTC. This event represents a routine, non-hazardous close approach within the broader Near-Earth Object tracking catalogue, with a miss distance that remains comfortably beyond the Earth–Moon system.


Parameter Value
Close Approach Date 27 March 2026
Time (UTC) 02:27
Nominal Distance 0.17170 au
Distance (km) ~25,685,800 km
Distance (Lunar Distances) ~66.8 LD
Relative Velocity ~19.8 km/s (~71,100 km/h)


Dynamical Interpretation


At a nominal separation of 0.17170 astronomical units, this flyby occurs at approximately 66.8 times the average Earth–Moon distance, placing it far outside the regime typically considered a “close” encounter in planetary defence terms.


Despite its classification as a Potentially Hazardous Asteroid, this designation is based on long-term orbital geometry (MOID and size) rather than immediate encounter conditions. The March 2026 passage represents a distant orbital crossing alignment rather than a near-Earth interaction.


Context Within NEO Monitoring Framework


For comparison, objects typically flagged for heightened observational campaigns during close approaches pass within <10 lunar distances, and in some cases within 1–2 LD. In contrast, 2013 FW13 remains well beyond even the outer boundary of the Earth–Moon system during this event.

The significance of this flyby is therefore observational rather than hazardous. Events at this scale are routinely used to refine orbital solutions, validate dynamical models, and maintain continuity in long-arc tracking datasets.

2026 Close Approach to Earth

Asteroid 879537 (2014 AF51) will make a notable close approach to Earth on 19 March 2026 at 21:10 TDB. This object is classified as an Amor-type Near-Earth Object (NEO) and a Potentially Hazardous Asteroid (PHA), although its orbit remains safely exterior to Earth's path at perihelion, and no impact risk is associated with this encounter.
Parameter Value Units
Close Approach Date (TDB) 2026-03-19 21:10 UTC / TDB
Nominal Distance from Earth 0.11658 AU (~17.4 million km)
Relative Velocity 8.94 km/s
Minimum Orbit Intersection Distance (MOID) 0.0222536 AU
Classification Amor, NEO, PHA

Although classified as potentially hazardous due to its size and orbital proximity thresholds, this March 2026 approach occurs at a distance more than 45 times the average Earth–Moon separation, placing it well outside any collision scenario. Its Amor-type orbit ensures that it does not currently cross Earth's orbital path, instead approaching from just beyond 1 AU at perihelion.
