A list of known near-Earth asteroid close approaches less than 1 lunar distance (384,400 km or 0.00256 AU) from Earth in 2012. [note 1] Rows highlighted red indicate objects which were not discovered until after closest approach. Rows highlighted yellow indicate objects discovered less than 24 hours before closest approach.
The small near-Earth asteroids 2008 TC 3, 2014 AA, 2018 LA, 2019 MO, 2022 EB 5, 2022 WJ 1, 2023 CX 1 and 2024 BX 1 are the only eight 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 closer than ...
This is a list of asteroids that have impacted Earth after discovery and orbit calculation that predicted the impact in advance. As of January 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 . Asteroid.
Near-Earth asteroids between Saturn's and Uranus'. zones of influence. 1999 XS 35. 17.915. Apollo asteroid, Damocloid asteroid, Mars-crosser asteroid, Jupiter-crosser asteroid, Saturn-crosser asteroid, Uranus-crosser asteroid, Neptune-crosser asteroid.
2012 BX. 34. 2012 BX34 is a small Aten asteroid that made one of the closest recorded asteroid close approaches of Earth on 27 January 2012. It passed within 0.0004371 AU (65,390 km; 40,630 mi) of Earth during its closest approach at 15:25 GMT. [6] 2012 BX34 measures around 8 meters (26 ft) across; if it had impacted in 2012, it would have been ...
Geosynchronous satellites have an orbit with semi-major axis length of 0.000282 AU (42,200 km; 26,200 mi) or 0.110 lunar distances. In 2017, five known asteroids have traveled nearer than this, 2017 GM, 2017 UJ2, YU95BEF, 2017 EA, and 2017 WE30. P10ELNY and A104Vqx probably have traveled nearer, but knowledge of their orbits is too poor to be sure.
An Earth-crosser is a near-Earth asteroid whose orbit crosses that of Earth as observed from the ecliptic pole of Earth's orbit. [1] The known numbered Earth-crossers are listed here. Those Earth-crossers whose semi-major axes are smaller than Earth's are Aten asteroids; the remaining ones are Apollo asteroids. (See also the Amor asteroids .)
Seven radar observations show the mile-wide asteroid 2011 UL21 during its June 27 close approach with Earth from about 4 million miles away. The asteroid and its small moon are circled in white.
