162173 Ryugu (provisional designation 1999 JU 3) is a near-Earth object and a potentially hazardous asteroid of the Apollo group. It measures approximately 900 metres (3,000 ft) in diameter and is a dark object of the rare spectral type Cb, [11] with qualities of both a C-type asteroid and a B-type asteroid .
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. Rows highlighted green indicate a comet ...
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.
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.
