This is a list of asteroids that have impacted Earth after discovery and orbit calculation that predicted the impact in advance. As of December 2024, all of the asteroids with predicted impacts were under 5 m (16 ft) in size that were discovered just hours before impact, and burned up in the atmosphere as meteors.
As sky surveys improve, smaller and smaller asteroids are regularly being discovered. The small near-Earth asteroids 2008 TC 3, 2014 AA, 2018 LA, 2019 MO, 2022 EB 5, 2022 WJ 1, 2023 CX 1, 2024 BX 1, 2024 RW 1, 2024 UQ, and 2024 XA 1 are the only eleven asteroids discovered before impacting into Earth (see asteroid impact prediction).
Asteroid close approaches to Earth in 2024 include: Asteroid Perigee Date in 2024 2009 JV 1: 0.0571 AU (19.21 LD) January 5 2021 BL 3: 0.0441 AU (17.16 LD) January 23 [1]
Before that, an asteroid named 2006 RH120, which orbits the sun and passes close to Earth every few decades, was captured by Earth’s gravity in June 2006 and stayed until around September 2007.
An asteroid burned up in the Earth’s atmosphere just hours after it was detected last month, the European Space Agency revealed in its latest newsletter. The asteroid, called 2024 UQ, was first ...
The other four asteroids that NASA talked about will be making their way past Earth over the next few days, with some coming a bit closer than asteroid 2008 OS7.
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 2023. [1] As most asteroids passing within a lunar distance are less than 40 meters in diameter, they generally are not detected until they are within several million km of Earth.
The expedition is all part of the steps NASA and other space agencies have taken in recent years to protect humanity from threats posed by asteroids and other inbound space rocks, such as comets ...
