Observatory Status & Data Integrity

Astrophyzix Planetary Defence reports are written using a fully dynamic, on-demand data retrieval pipeline linked directly to NASA's CNEOS NeoWs API infrastructure.

The monitoring interval is calculated at runtime and spans seven days forward from the exact timestamp of system access.

No caching layers, pre-processing, or static datasets are used. Every value presented is sourced from the most recent orbital solutions available within NASA systems at the time of query execution by the Astrophyzix Planetary Defence System.

Certain data is computed through the Astrophyzix Risk Index and presented alongside the raw data to give readers an easy to visualise scale of how notable an object is an a clear interpretation of the data.

Introduction

Asteroid 192559 (1998 VO) is a well-characterised Apollo-class near-Earth object (NEO) classified as a Potentially Hazardous Asteroid (PHA). With a data arc spanning over two decades and hundreds of observations, its orbit is extremely well constrained, allowing for precise modelling of its trajectory across both past and future epochs.

The close approach on 2026-Apr-14 10:04 (TDB) represents a routine, distant flyby with no impact risk. Its PHA classification reflects orbital geometry (Earth-crossing potential) and size thresholds, not an immediate threat.

Potentially Hazardous Asteroid (PHA) news refers to verified reports of near-Earth asteroids that meet specific size and orbital proximity thresholds. Despite the classification, the vast majority of PHAs pose no impact threat during observed close approaches.

Key Takeaways

• Close approach on 2026-Apr-14 10:04 (TDB).
• Miss distance: 0.32726 AU (~127.3 LD / ~48.9 million km).
• Relative velocity: 17.60 km/s.
• Estimated diameter: ~300–700 meters.
• Condition code 0 (orbit extremely well constrained).
• No impact threat identified.
• Astrophyzix Risk Index® Notibility score: 48 (Elevated).

Scientific Consensus Snapshot

The orbit of 192559 (1998 VO) is derived from 575 observations spanning 1998-11-10 to 2018-11-13, producing a condition code of 0—the highest confidence level in orbit determination. The timing uncertainty for the 2026-Apr-14 10:04 (TDB) encounter is less than one minute, indicating negligible positional uncertainty.
