NASA Shares Observations of Recently-Identified Near Earth Asteroid
Jan 29, 2025 · 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. Such initial analysis will change over time as more observations are gathered.

Asteroid 2024 YR4 reaches level 3 on the Torino Scale
6 days ago · NASA analysis of a near-Earth asteroid, designated 2024 YR4, indicates it has a small chance of impacting Earth on Dec. 22, 2032. ... 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 ...

Study Finds Earth’s Small Asteroid Visitor Likely Chunk of Moon …
Jan 22, 2025 · Asteroid Lunar Studies. The discovery of 2024 PT5 doubles the number of known asteroids thought to originate from the Moon. Asteroid 469219 Kamo’oalewa was found in 2016 with an Earth-like orbit around the Sun, indicating that it may also have been ejected from the lunar surface after a large impact. As telescopes become more sensitive to smaller asteroids, more potential Moon boulders will ...
