3753 Cruithne is a Q-type, Aten asteroid in orbit around the Sun in 1:1 orbital resonance with Earth, making it a co-orbital object. It is an asteroid that, relative to Earth, orbits the Sun in a bean-shaped orbit that effectively describes a horseshoe, and that can change into a quasi-satellite orbit.

Orbital period: 364 days

Radius: 1.5534 mi

Gravity: 0.0014 m/s²

Orbits: Sun

Mean motion: 0° 59^m 20.436^s / day

Did you know: Cruithne orbits the sun about once a year, but it takes nearly 800 years to complete this messy ring shape around the Earth's orbit.
