2025年1月31日 · 2024 YR4 is currently observable and being tracked with several telescopes, including the Magdalena Ridge Observatory in New Mexico, the Danish Telescope, and the Very Large Telescope in Chile. As the asteroid moves away from Earth and becomes fainter, larger and larger telescopes will be required to detect it. The asteroid should remain ...

1 天前 · Dubbed 2024 YR4, the asteroid was first spotted on December 27, 2024, by the El Sauce Observatory in Chile. Based on its brightness, astronomers estimate it is between 130 and 300 feet wide.

2 天之前 · As 2024 YR4 is currently very close to these size and impact probability thresholds, the group has decided to continue monitoring the situation before initiating any further action. SMPAG will meet again in late April or early May as the asteroid fades from view to re-evaluate the situation, or earlier in the unlikely event that the impact risk ...

2025年1月29日 · Asteroid 2024 YR4 has an almost 99% chance of safely passing Earth on 22 December 2032, but a possible impact cannot yet be entirely ruled out.; The asteroid is estimated to be between 40 m and 100 m wide.

2025年1月29日 · NASA analysis of a near-Earth asteroid, designated 2024 YR4, indicates it has a more than 1% chance of impacting Earth on Dec. 22, 2032 – which also means there is about a 99% chance this asteroid will not impact.

4 天之前 · Preparing for asteroid 2024 YR4. Astronomers will soon switch to more powerful telescopes to track 2024 YR4 as it dims. They aim to collect enough measurements to refine orbital calculations and ease public concerns. SMPAG’s meeting next week will focus on next steps if the risk level remains the same.

3 天之前 · YR4 was detected on 27 December 2024. Astronomers calculated that it was between 40m and 90m across. This would have the power of a nuclear bomb were it to hit the Earth and cause severe damage if ...
