Close-up of Earth's rare minimoon captured by Tianwen-2
China's Tianwen-2 mission delivered the first close-up image of Earth's rare quasi-satellite Kamoʻoalewa (2016HO3) from about 20 km away after a year-long journey. The probe will study the rock, collect samples to return to Earth, and then proceed to main-belt comet 311P, advancing our understanding of near-Earth asteroids and their origins.
