Asteroid 2024 YR4: Chances of collision with Earth in 2032 increased to 2.3%

  • 6 תגובות
NASA and international scientists are monitoring new data to determine the risk of a collision and potential impacts. Since it is a short-range event, actions to deal with it have already begun. Among other things, China has launched a campaign to recruit experts for the "protection" team.

Asteroid 2024 YR4 has been identified by NASA with a low chance – just over 1% – of colliding with Earth in December 2032. Scientists continue to collect data and refine calculations to assess the true risk.

A new study shows that the Taurid swarm contains fewer large asteroids than predicted, so the risk level from it is lower.

A new study reveals that most of the meteorites on Earth were formed as a result of collisions that occurred in the asteroid belt in the last tens of millions of years. The discovery provides new insights into the origins of meteorites and the possible threat to Earth

Hubble Space Telescope image of the barred spiral galaxy UGC 12158. The majestic galaxy has a pinwheel shape consisting of bright blue stars surrounding a yellow-white concentration of central stars. This concentration has a diagonal line of stars across it, called a bar. The galaxy is tilted inward to our view from Earth. A white S-shaped line slightly across the top is the Hubble image of an asteroid hovering across the field of view.. It looks dashed because the image is a composite of several exposures of the asteroid flying like a race car. Credit: NASA, ESA, PG Martín (Autonomous University of Madrid), J. DePasquale (STScI).
