[2] [1] As of 6 February 2025, 2024 YR 4 was rated 3 on the Torino scale with a 1 in 43 (2.3%) chance of impacting Earth on 22 ...

Jan 29, 2025 · Asteroid 2024 YR4 is now rated at Level 3 on the Torino Impact Hazard Scale: a close encounter that warrants attention from astronomers and the public. It is important to remember that an asteroid’s impact probability often rises at first before quickly dropping to zero after additional observations. For an explanation of why this happens ...

Jan 31, 2025 · Asteroid 2024 YR4 is most likely in the range of 40 to 90 meters (130 to 300 feet) in size. This estimate is based measurements of the asteroid’s brightness. The size cannot be further constrained without thermal infrared observations, radar observations, or imagery from a spacecraft that could closely approach the asteroid. ...

2 days ago · 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.

Jan 29, 2025 · Asteroid 2024 YR4 was first reported on Dec. 27, 2024, to the Minor Planet Center– the international clearing house for small-body positional measurements – by the NASA-funded Asteroid Terrestrial-impact Last Alert System station in Chile. The asteroid, which is estimated to be about 130 to 300 feet wide, caught astronomers’ attention ...

1 day ago · Asteroid 2024 YR4 is now rated at Level 3 on this scale, meaning it merits close attention by astronomers, the public, and government officials. This is the second time an asteroid has reached ...

3 days ago · The February 2025 edition focusses on asteroid 2024 YR4. 3 Feb: The Space Mission Planning Advisory Group will continue to monitor the situation. SMPAG coordinates the international response to any asteroid larger than 50 m across with a greater than 1% chance of impacting Earth within the next 50 years. As 2024 YR4 is currently very close to ...

5 days ago · 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. By staying informed and ready, experts ...

Jan 30, 2025 · Ratings of 1 are fairly common among newly discovered asteroids, but follow-up observations have always reduced that rating to 0. Asteroid 2024 YR4’s rating of 3 is the second-highest an asteroid has ever reached. The only asteroid ranked higher was Apophis, discovered in 2004 and rated 4, but subsequently downgraded to 1 and then 0. We now ...

4 days ago · The probability that the asteroid, called 2024 YR4, may impact Earth on 22 December 2032 is currently estimated to be 1.3%. Dr Robert Massey of the Royal Astronomical Society, says that he is "not ...
