Live Independent Verifiable and reproducible Unpaywalled NASA-sourced

Astrophyzix Digital Observatory

Trusted for Asteroid News, Research, Data & Analysis

Delivering unpaywalled, evidence-driven analysis, public research tools, real-time datasets and monitoring and tracking of all PHA/NEO asteroids, comets and solar system objects.

Every tracking console is designed and engineered here. Systems directly ingest multiple NASA datasets covering over 1.57 million objects, then run live, verifiable probabilistic orbital analysis and deliver an instant deterministic summary of close approaches. Used by students, educators, researchers, and the public. Data provenance is traceable, verifiable and transparent. Original research papers are published on Astrophyzix.academia.edu, registered with official DOIs via Zenodo and academically indexed by OpenAIRE.

Live PHA/NEO Tracker, CNEOS Scout, Sentry & Orbital Viewer (NASA/JPL) Astrophyzix Observatory
LIVE PHA & NEO ASTEROID TRACKING
Live Multi-Watch Asteroid Tracking & NASA CAD /Scout/Sentry System V9.0

LIVE PHA/NEO ASTEROID TRACKER
NASA CAD - SCOUT - SENTRY - SBDB

Live console for confirmed near-Earth NEO/PHA close approaches (NASA/JPL SBDB CAD API), unconfirmed candidates on the Minor Planet Center's NEO Confirmation Page (NASA CNEOS Scout API), and officially tracked impact-risk objects (NASA CNEOS Sentry API). Orbital elements and physical parameters are pulled from JPL's Small-Body Database (SBDB) on demand. Requests are relayed through our custom-built console using a traceable, publicly accessible CORS-proxy fallback chain, ensuring that Astrophyzix operates in accordance with the terms and conditions governing public API usage on NASA.gov - This enables us to show genuinely live and comprehensive data with unrivalled depth. — see System Health for relay status and fully verifiable, transparent data provenance pipelines. Please be patient while the data is fetched and use the "manual sync" button to retrieve the very latest unfiltered, official data sets - live on demand. No login required.

Approach Radar Lunar-distance scale · rank-ordered bearing (schematic)
Schematic radar plot. The object list below contains the same data in accessible tabular form.

Bearing is rank-ordered for visual separation, not true sky position — CAD/Scout summary data does not include right ascension/declination at closest approach. Tap or focus a point for details.

Sentry Impact-Risk Watchlist Official CNEOS Sentry-II data · real Palermo/Torino scale values
Loading Sentry summary…

Sentry monitors objects with a non-zero computed chance of Earth impact over the next ~100 years. Presence on this list does not mean an impact is likely — nearly all listed objects will be removed as more observations refine their orbits. This is the same official data referenced in the ARI methodology disclaimer.
