Asteroid 2024 YR4 is a near‑Earth object discovered in late 2024. Based on its brightness, it is roughly on the order of tens to a few hundred meters across; continued optical (and where available, radar) observations through 2026‑04‑12 have substantially improved the precision of its orbit.
Planetary‑defense networks are continuing to monitor 2024 YR4 and update trajectory solutions as new data arrive. Current orbital determinations show no predicted impact threat in the near term, and routine follow‑up observations will keep improving long‑range forecasts.
