Earth's second #moon #Cruithne (/kruːˈiːnjə/ or /ˈkrʊnjə/) 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 transition into a quasi-satellite orbit.
