469219 Kamoʻoalewa (/ k ə ˌ m oʊ ʔ oʊ ə ˈ l ɛ v ə /), [6] provisionally designated 2016 HO 3, is a very small elongated asteroid, fast rotator and near-Earth object of the Apollo group, approximately 40–100 meters (130–330 feet) in diameter.
The asteroid Kamo’oalewa—which in Hawaiian means “the oscillating fragment”—is a small (by asteroid standards) chunk of rock roughly the size of a ferris wheel. Its quasi-satellite ...
An asteroid that orbited near Earth for a few months as a mini-moon may be a chunk of the moon that was blasted off by an impact thousands of years ago. ... The discovery of Kamo’oalewa excited ...
Asteroid 469219 Kamo’oalewa was found in 2016 orbiting the sun, suggesting it may also have been ejected from the lunar surface after a large impact. What's more, astronomers believe that still ...
2023 FW 13 is an asteroid that was spotted on March 28, 2023, from the Pan-STARRS telescope at Hawaii, United States. It circles the sun in sync with Earth in such a way that it appears to orbit Earth, but well outside Earth's Hill sphere, making it a quasi-satellite.
Kaʻepaokaʻāwela is the first example of an asteroid in a 1:–1 resonance with any of the planets. [5] This type of resonance had only been studied a few years before the object's discovery. [10] [11] One study suggests that it was an interstellar asteroid captured 4.5 billion years ago into an orbit around the Sun.
In 2016, astronomers spotted an asteroid about the size of a ferris wheel in an Earth-like orbit around the Sun. Turns out it's actually a chunk of the moon.
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.
