Update for 2026-04-17: Astronomers reported new optical and radar observations of asteroid 2024 YR4 today. The additional data have tightened the asteroid’s orbit and rotation parameters, reducing uncertainties in its trajectory around the Sun. The revised orbit confirms it remains a routinely monitored near-Earth object and does not present an impact threat in the near term.
The new measurements also improved constraints on 2024 YR4’s size and shape, showing it to be a small, irregular body typical of near-Earth asteroids. Observatories will continue periodic tracking to refine its orbit further and to plan future observing opportunities during the next favorable windows.
