The earth will not be called2024 yr4The threat of the asteroid, an asteroid that is enough to level a city, but7The moon will not be so safe after the New Year.
Asteroid2024 yr4At2024Year12moon27On Sunday, the “Asteroids” located in Rio Urtado, ChileEarthImpact warning systemโ (ATLAS) Discovery has attracted the attention of the international community.2024 yr4It is huge and known as the “city killer”, and has jumped to the most threatening asteroid in the “Durin Danger Index“.
The Dulin hazard index is a classification system used to assess the risk of near-Earth celestial bodies hitting the earth. The higher the rating, the higher the level of danger.2024 yr4The chance of hitting the earth once rose to its highest3.1%. but,2025Year2In late month, scientists reduced the probability of the asteroid hitting the Earth to almost zero through more precise observations.
After the earth is safe,2024 yr4exist7The chances of hitting the moon, the neighbor of Earth, continue to rise after the New Year.
NASA (NASA) James Webb Space Telescope (Jwst)exist5The month captures 2024 TheThe latest glimpse. By Dr. Rifkin (Andy Rivkin) led a team in collaboration with the Johns Hopkins University Applied Physics Laboratory to use the Weber Space Telescope’s near-infrared camera pair2024 yr4Perform accurate observations.
according toJwstInformation andNASAExperts from the Near-Earth Celestial Research Center have analyzed that the orbit of this asteroid has been accurately calculated, and it is2032Year12moon22The chances of the sun hitting the moon, from3Monthly observation3.8%Rise to5Monthly observation4.3%ใ

2024 yr4The estimated length is174~220Foot (approximately53~67Meter), equivalent to one building10~15A tall building.NASAIt means that if the asteroid really collides with the moon, it will not change its orbit, and the earth will be safe.
