'''2022 YG''' is a [[near-Earth asteroid]] and a potential [[quasi-satellite]] of Earth, discovered by [[amateur astronomer]] [[Gennadiy Borisov]] at [[Nauchnyi]], [[Crimea]] on 15 December 2022. It has an estimated diameter of 16–30 meters, given [[Absolute magnitude#Solar System bodies (H)|H]] of 26.7, and an albedo 4-15%.{{efn|[[Absolute magnitude#Planets as diffuse spheres]] <math display="block">D = \frac{1329}{\sqrt{p}} \times 10^{-0.2H} \mathrm{km}.</math>}} Its closest approach to Earth was on 22 December 2022, at a distance of 0.0163 [[Astronomical unit|AU]].<ref name="jpldata"/>
