Asteroid 2026 HZ3 Key Takeaways

• Newly discovered NEO: (2026 HZ3) is a recently observed Apollo-class near-Earth asteroid with a short data-arc (4 days) and a relatively high orbital uncertainty (condition code 7).
• Small object: With an absolute magnitude H ≈ 25.3, (2026 HZ3) is likely a small asteroid, on the order of a few tens of metres in diameter, depending on its surface reflectivity.
• Close approach in 2026: A nominal close approach to Earth occurs on 1 May 2026 at a distance of about 0.010 au (around 1.5 million km), well outside any impact scenario under current solutions.
• Earth MOID: The current Minimum Orbit Intersection Distance (MOID) with Earth is about 0.00497 au (~745,000 km), indicating close-approach potential but not an imminent threat.
• Preliminary orbit: Because the orbit is based on only 38 observations over 4 days, all risk and trajectory assessments are considered preliminary and will be refined as more data are collected.

Introduction

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.

Scientific Consensus Snapshot

The current orbital solution for (2026 GU) is based on a short observational arc and remains subject to refinement. While the object's classification as a PHA reflects its long-term orbital geometry, the 14 April 2026 encounter is well outside any hazardous threshold. Future observations will reduce uncertainties and improve long-term trajectory modelling.

Introduction

New updates found in our JPL Solution 2 Report

Asteroid (2026 GD) is a recently observed Apollo-class near-Earth object (NEO) identified in April 2026. With a short observational arc of just 1 day, its orbital solution remains preliminary and subject to refinement. Despite this, current data indicates an exceptionally close Earth approach occurring on 09 April 2026.

The object’s very low Earth Minimum Orbit Intersection Distance (MOID) and near-term encounter geometry place it within the category of close-approach monitoring priority objects, although no confirmed impact risk is currently established based on available solutions at this time. Astrophyzix will update you as new data comes in. 

Key Takeaways

• Apollo-class near-Earth asteroid with Earth-crossing orbit.
• Very close Earth approach on 2026-Apr-09 at ~0.00168 AU.
• Equivalent to approximately 0.65 lunar distances (~251,000 km).
• Estimated relative velocity: ~12.66 km/s.
• Small object (~20–30 meters estimated diameter range).
• Extremely low Earth MOID: 0.000525 AU.
• Orbit uncertainty remains high (condition code 7).
• No confirmed impact risk in current datasets at the time of this report. 

Scientific Consensus Snapshot

The orbital parameters for (2026 GD) are based on a limited observational dataset spanning approximately one day. As a result, uncertainties remain significant, reflected in its condition code of 7. (Explanation of Code 7 below) 

Additional observations are required to refine its trajectory and reduce positional uncertainty. Close-approach predictions at this stage should be treated as provisional.
