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.
When many photons hit an object, they can speed it up or slow it down. ... Astronomers found asteroid 469219 Kamo’oalewa in 2016, which was also likely ejected from the lunar surface after ...
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 ...
Kamo'oalewa has an odd near-Earth orbit that perplexed scientists, especially given that its composition is not like other near-Earth satellites. How did part of the moon become a near-Earth asteroid?
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.
After limiting crater size based on simulations of impacts that could eject a piece this large into a quasi-satellite orbit, and limiting crater age to between 1 and 10 million years based on the instability of the asteroid's orbit, a 2024 study found that the most likely origin is the Giordano Bruno crater.

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.
