借助在旗舰级全天区测绘任务开始前采集的早期巡天数据，Vera C. Rubin 天文台已将 11,000 颗新识别的小行星加入太阳系天体名录。
当阿波菲斯小行星在2029年4月做出有史以来最近的地球接近时，它将被多个航天器迎接——包括私营登陆器——这将是有史以来最雄心勃勃的小行星遭遇任务。
NASA's Daily Minor Planet citizen science project has expanded to include data from the powerful Bok 2.3-meter telescope at Kitt Peak, enabling detection of near-Earth asteroids two to three times fainter than before.
The Vera Rubin Observatory's Legacy Survey will detect one-meter class objects heading for Earth, enabling precise impact site predictions.
Fan-like patterns on Dimorphos confirm material transfer between binary asteroids, a first in planetary science.
NASA has confirmed that its DART mission not only altered Dimorphos's orbit around Didymos but actually changed the asteroid system's orbit around the sun.
The Vera C. Rubin Observatory in Chile, featuring the world's largest digital camera at 3.2 gigapixels, is preparing to begin its decade-long survey of the southern sky. In its first year alone, the telescope will catalog more objects than every other optical observatory in human history combined.
