• Asteroid 2023 UH9 flew past Earth at 0.2 LD

    A newly-discovered asteroid designated 2023 UH9 flew past Earth at a distance of 0.27 LD / 0.00070 AU (104 456 km / 64 906 miles) from the center of our planet at 17:12 UTC on October 18, 2023.

  • Asteroid Polyhymnia’s density beyond known elements

    A groundbreaking study by the University of Arizona reveals that asteroid Polyhymnia has a density exceeding that of any known elements on Earth. Led by Jan Rafelski, the research team used the Thomas-Fermi model to predict the existence of superheavy elements that could account for this extraordinary density. These findings not only challenge our understanding of the Periodic Table but also have significant implications for future asteroid mining endeavors.
