Which Celestial Bodies Are Earth's "Quasi-Satellites"?

Quasi-satellites are asteroids that orbit the Sun but remain in a 1:1 orbital resonance with Earth, appearing to orbit our planet without being gravitationally bound.

The top 3

1. Kamoʻoalewa: Earth's Most Stable Quasi-Satellite: Kamoʻoalewa (2016 HO3) is considered Earth's most stable known quasi-satellite, following a bean-shaped path around Earth relative to the Sun and possibly being a fragment of the Moon.
2. Other Earth Co-Orbital Asteroids: Beyond Kamoʻoalewa, Earth has several other known quasi-satellites, including 2023 FW13 and 2025 PN7, though their stability in this configuration varies over time.
3. Quasi-Satellites vs. True Moons: Unlike a true moon gravitationally bound to a planet, a quasi-satellite primarily orbits the Sun, sharing the planet's orbital period but with a more eccentric path, making it a temporary companion.
