Solar System

Co-orbital Objects

Bodies that share Earth’s year around the Sun without orbiting Earth: quasi-moons such as Kamoʻoalewa, and horseshoe companions such as 3753 Cruithne.

Earth and (277810) 2006 FV35

Earth with quasi-moon (277810) 2006 FV35 in 1:1 resonance — co-orbiting the Sun with Earth — on JPL Horizons states for 1 January 2025.

Earth and 2013 LX28

Earth with quasi-moon 2013 LX28, a 110–250 m asteroid in temporary 1:1 resonance with Earth, on JPL Horizons heliocentric states for 1 January 2025.

Earth and 2014 OL339

Earth with quasi-moon 2014 OL339, a ~70–160 m asteroid in temporary 1:1 resonance with Earth, on JPL Horizons heliocentric states for 1 January 2025.

Earth and 2022 YG

Earth with quasi-moon 2022 YG, a ~16–30 m asteroid in 1:1 resonance discovered by Gennadiy Borisov, on JPL Horizons states for 1 January 2025.

Earth and 2023 FW13

Earth with quasi-moon 2023 FW13, a decametre-scale asteroid in 1:1 resonance discovered by Pan-STARRS, on JPL Horizons states for 1 January 2025.

Earth and 2025 PN7

Earth with quasi-moon 2025 PN7, the newest known Earth quasi-satellite (discovered August 2025), on JPL Horizons states for 1 January 2025.

Earth and Cardea (2004 GU9)

Earth with quasi-moon 164207 Cardea (2004 GU9) on a 1:1 resonant path — co-orbiting the Sun beside Earth, not bound as a satellite — using JPL Horizons states for 1 January 2025.

Earth and Cruithne (3753)

Earth with asteroid 3753 Cruithne, the first-known co-orbital companion of Earth — locked in a 1:1 mean-motion resonance but on a horseshoe path rather than a quasi-satellite loop — using JPL Horizons states for 1 January 2025.

Earth and Kamoʻoalewa (2016 HO3)

Earth with quasi-moon 469219 Kamoʻoalewa (2016 HO3), the most stable known Earth co-orbital — in 1:1 resonance since at least 1900 — on JPL Horizons states for 1 January 2025.
