The average distance to the Moon (or lunar distance (LD)) is about 384,400 km (238,900 mi), which is around 30 times the diameter of the Earth. [3] Below are lists of close approaches less than one LD for a given year. (See also near-Earth asteroids and NEO Earth Close Approaches.)
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. Objects coming from the ...
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]
NASA scientists flag locations along these objects paths as close approaches when they are slated to arrive at points within 4.6 million miles from the Earth's surface, which equates to roughly 19 ...
During 2022 about 124 asteroids passed within 1 LD of Earth. 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. For reference, the radius of Earth is about 0.0000426 AU (6,370 km; 3,960 mi) or 0.0166 lunar distances.
Radar image of 2020 BX 12 and its satellite during close approach in February 2020 Path of 1998 OR 2 near close approach to Earth in April 2020. 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 2020.
Earth has a new “mini-moon” after an asteroid has joined our orbit. The object, known as 2024 PT5, has been chasing after us for years. Now, it has become close enough to be pulled in by our ...
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 [update] , 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 .
