One more moon, kind-of

There’s another sorta, kinda moon in a sorta, kinda orbit around Earth that was discovered only in 2016. The quasi-moon - named Kamo’oalewa, after a Hawaiian word that refers to a moving celestial object - is not much to speak of, measuring less than 50 m (164 ft) across.

It circles the Earth in a repeating corkscrew-like trajectory that brings it no closer than 40 to 100 times the 384,000 km (239,000 mi.) distance of our more familiar moon. Its odd flight path is caused by the competing gravitational pulls of the Earth and the sun, which continually bend and torque the moonlet’s motions.
