2023 FW13
2023 FW13 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.
The orbit of 2023 FW13 has a one-to-one resonance with Earth and is very eccentric, reaching out halfway to Mars and halfway to Venus. It's estimated that it has circled Earth since 100 B.C. and will continue until 3700 A.D. If those estimates are correct, it would significantly overtake 469219 Kamoʻoalewa as the most stable quasi-satellite of Earth.
