2024 YR4 is an asteroid with the potential to impact Earth on 22 December 2032. The latest impact probabliities can be found on the object pages below.
- The asteroid was first observed by the ATLAS Chile site (MPC Code W68) on 27 December 2024, with precovery images extending back to 25 December 2024.
- Observations by the world wide network of observers can be found on the MPC 2024 YR4 page.
- The absolute magnitude value is approximately 24. Its size is estimated to be in the 40-90 meter range.
- The asteroid's spectra has been observed, and is consistent with possibly an S or L spectral type (J. de Lèon, on the GTC, and N. Moskovitz, on the LDT).
- VLT data (M. Devogele) and La Silla 1.54 meter data (P. Pravec) indicate a rotational period near 19.5 minutes. The VLT observers have also obtained phase curve coverage from 5 to 35 degrees.
