A list of known near-Earth asteroid close approaches less than 1 lunar distance (384,400 km or 0.00257 AU) from Earth in 2012, based on the close approach database of the Center for Near-Earth Object Studies (CNEOS). [1]
A list of known near-Earth asteroid close approaches less than 1 lunar distance (0.0025696 AU (384,410 km; 238,860 mi)) from Earth in 2021, based on the close approach database of the Center for Near-Earth Object Studies (CNEOS). [1] For reference, the radius of Earth is about 0.0000426 AU (6,370 km; 3,960 mi) or 0.0166 lunar distances.
This is a list of asteroids that have impacted Earth after discovery and orbit calculation that predicted the impact in advance, which are cataloged by the Center for Near-Earth Object Studies (CNEOS).
The asteroid, described as "very small" by NASA, impacted Earth's atmosphere around 11:14 a.m. ET and created a fireball over eastern Russia, the space agency said in a post on X.
English: 2021 NASA Science Calendar 2021 NASA Science Calendar: Science and discovery have always required us to persevere. Through unprecedented times. Through storms and turbulence. Perseverance is more than facing challenges. It demonstrates our ability to hold on to a worthy goal with resilience.
The odds that asteroid 2024 YR4 could hit Earth in 2032 recently spiked from a little more than 1% to 2.3% as more observations are made. ... first spotted late last year on a potential collision ...
The asteroid that slammed into Earth 66 million years ago and led to the extinction of dinosaurs was estimated to be about 6.2 miles (10 kilometers) in diameter and marked the last known large ...
1950 DA made distant approaches to Earth on 20 May 2012, 5 February 2021 and 5 February 2023. [18] However, at these times it was a quarter to half an AU away from Earth, preventing more useful astrometrics and timing that occurs when an object is closer to Earth. The next close approach that presents a good opportunity to observe the asteroid ...
