The largest asteroid to pass within 1 LD of Earth in 2021 was 2021 SG with an estimated diameter of around 68 meters and an absolute magnitude of 24.0. The fastest asteroid to pass within 1 LD of Earth in 2021 was 2021 UA 7 that passed Earth with a velocity with respect to Earth of 27.7 km/s (62,000 mph). [2] [note 2]
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 ...
Risk-listed asteroid 2007 VE 191 (~60 meters in diameter) was not observed when it probably passed roughly 0.5 AU (75,000,000 km; 46,000,000 mi) from Earth on 27 November 2015. 2015 YB initially calculated to make a close approach to Earth on 19 December 2015 turned out to be a much further away inner main-belt asteroid.
The location of 2024 YR4 qualifies it not just as any asteroid, but a near-Earth object (NEO). NEOs are defined as asteroids that hug the inner solar system, where we live, coming within 1.3 ...
A small asteroid was visible in northern Siberia on Tuesday, as it closed in on its collision course with Earth. The European Space Agency issued an alert for the 27-inch asteroid at 4:27 a.m. ET ...

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.
2015 DR 215 was discovered on 18 February 2015 by the Pan-STARRS 1 survey at Haleakalā Observatory at Maui, Hawaiʻi. [2] It was first observed at apparent magnitude 20.7, located in the southern sky 28 degrees below the ecliptic with an angular separation (solar elongation) of 76 degrees from the Sun. [2] Follow-up observations from the Mauna Kea Observatory and Cerro Tololo Inter-American ...
