**PASADENA, United States, Nov. 4, 2026 -** NASA/JPL CNEOS has published Sentry impact risk entries for eight near-Earth asteroids, all with calculated impact probabilities for 4 November 2026.

All listed probabilities remain extremely low. No object on the list carries an impact chance greater than 1.15%.

Asteroid 2017 WT28 has the highest listed probability at 0.011544. [^1] Next is 2026 CQ4 at 0.00503041. [^2] Remaining objects in descending order are 2025 DT2, 1950 DA, 2008 JL3, 2021 GX9, 2023 BZ and 2024 JW16. [^3] [^4] [^5] [^6] [^7] [^8]

None of the objects are rated as presenting an immediate hazard. All entries are standard automated monitoring outputs from the Sentry system.

**Impact Insight.**
The Sentry system is NASA's automated near-Earth object monitoring service, which continuously calculates possible future impact trajectories for all catalogued asteroids. Entries on this list do not mean an impact is expected; they represent all mathematically possible outcomes within the current uncertainty of each object's measured orbit. Regular updates to orbit measurements almost always remove objects from this list as uncertainty is reduced.
