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, and 2024 RW 1 are the only nine asteroids discovered before impacting into Earth (see asteroid impact prediction). Scientists estimate that several dozen asteroids in the 6–12 m (20–39 ft) size range fly by Earth at a distance ...
Beyond 1 LD. Below is an example list of near-Earth asteroids that nominally will pass more than 1 lunar distance (384,400 km or 0.00256 AU) from Earth in 2023. During 2022, over 1,000 asteroids passed within 10 LD (3.8 million km) of Earth. Rows highlighted grey indicate a planet or main-belt asteroid.
A list of known near-Earth asteroidclose approaches less than 1 lunar distance(0.0025696 AU (384,410 km; 238,860 mi)) from Earthin 2022.[1] During 2022 about 124 asteroids passed within 1 LD of Earth. As most asteroids passing within a lunar distanceare less than 40 meters in diameter, they generally are not detected until they are within ...
Goldstone radar images of asteroid 99942 Apophis on 8–10 March 2021. Goldstone radar images of asteroid 2001 FO 32 during closest approach on 21 March 2021. Below is an example list of near-Earth asteroids that passed or will pass more than 1 lunar distance (384,400 km or 0.00256 AU) from Earth in 2021. Object.
A near-Earth object (NEO) is any small Solar System body orbiting the Sun whose closest approach to the Sun (perihelion) is less than 1.3 times the Earth–Sun distance (astronomical unit, AU). [ 2 ] This definition applies to the object's orbit around the Sun, rather than its current position, thus an object with such an orbit is considered an ...
List of asteroid close approaches to Earth in 2024. Asteroid close approaches to Earth in 2024 include: 2009 JV1 close approach, 0.0571 AU (19.21 LD) on January 5, 2024. 2021 BL3 close approach, 0.0441 AU (17.16 LD) on January 23, 2024 [1] 2017 BG92 close approach, 0.0301 AU (11.71 LD) on January 25, 2024.
99942 Apophis (provisional designation 2004 MN4) is a near-Earth asteroid and a potentially hazardous object with a diameter of 370 metres (1,210 feet) [ 3 ] that caused a brief period of concern in December 2004 when initial observations indicated a probability up to 2.7% that it would hit Earth on April 13, 2029.
Near-Earth asteroids, or NEAs, are asteroids that have orbits that pass close to that of Earth. Asteroids that actually cross Earth's orbital path are known as Earth-crossers. As of April 2022, a total of 28,772 near-Earth asteroids were known; 878 have a diameter of one kilometer or larger. [51]
