    ByTeo Blašković

    A newly-discovered asteroid designated 2023 XJ1 will fly past Earth at a distance of 0.27 LD / 0.00066 AU (98 242 km / 61 045 miles) from the center of our planet at 18:57 UTC on December 6, 2023.

  • Yale-led study reveals orbital tilt in pristine solar systems as common phenomenon

    ByTeo Blašković

    A new study spearheaded by Yale astronomer Malena Rice and published in The Astronomical Journal has made a significant discovery about the orbital tilt of planets in pristine solar systems. Contrary to previous assumptions that slanted orbits result from cosmic disturbances, this research suggests that even in stable solar systems, planets can exhibit an orbital tilt of up to 20 degrees.

  • Asteroid 2023 WA to fly past Earth at 0.07 LD

    ByTeo Blašković

    A newly-discovered asteroid designated 2023 WA will fly past Earth at a distance of just 0.071 LD / 0.00018 AU (27 379 km / 17 012 miles) from the center of our planet at 03:41 UTC on November 17, 2023.

  • Asteroid 2023 VB2 flew past Earth at 0.085 LD

    ByTeo Blašković

    A newly-discovered asteroid designated 2023 VB2 flew past Earth at a distance of 0.085 LD / 0.00022 AU (32 769 km / 20 362 miles) from the center of our planet at 07:00 UTC on November 7, 2023. This is one of 3 asteroids to fly past Earth within 1 lunar distance today — the others are 2023 VS at 01:18 UTC and 2023 VD2 at 12:53 UTC.

  • Evidence of cataclysmic planetary collision 1 800 light years from Earth

    ByTW

    In December 2021, astronomers observed unprecedented fluctuations in the light of a star identified as ASASSN-21qj, located 1 800 light years away from Earth. Now, a study published in Nature suggests these fluctuations were the result of a colossal collision between two giant planets, potentially providing a rare opportunity to witness the birth of a new planet.

  • Asteroid 2023 UH9 flew past Earth at 0.2 LD

    ByTeo Blašković

    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

    ByTW

    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.
