Could this asteroid be a piece of the moon? A Chinese spacecraft is about to find out

China’s Tianwen-2 mission is approaching quasi-satellite 469219 Kamo’oalewa to determine whether it is a lunar fragment or a weathered LL chondrite asteroid. Kamo’oalewa is 30-60 metres wide, rotates once every 28 minutes, and sample-return analysis could reveal its mineral and isotopic origin.
