科学家在2025年的一次调查中,利用鲁宾天文台的先进相机,发现了一颗快速喷射的、1,640英尺宽的小行星,即2025 MN45。 Scientists found a fast-spinning, 1,640-foot-wide asteroid, 2025 MN45, using the Rubin Observatory’s advanced camera during a 2025 survey.

科学家发现了小行星2025 MN45,宽度超过1,640英尺,旋转速度比任何类似大小的小行星都快,在5分钟内完成旋转。 Scientists have discovered asteroid 2025 MN45, over 1,640 feet wide and spinning faster than any similar-sized asteroid ever seen, completing a rotation in under five minutes. 2025年4月和5月进行为期七天的调查发现,该发现利用Vera C. Rubin天文台的强力摄像头发现了近2 000个新小行星,其中包括16个超快和3个超快旋转器。 Found using the Vera C. Rubin Observatory’s powerful camera during a seven-day survey in April and May 2025, the discovery revealed nearly 2,000 new asteroids, including 16 super-fast and three ultra-fast rotators. 大多数是近地物体,但没有任何物体在下一个世纪构成威胁。 Most are near-Earth objects, but none pose a threat in the next century. 该观测站的先进成像探测到了火星和木星区域之间主要地带迅速流转的小行星——这些物体以前很难发现——标志着观测能力的重大飞跃。 The observatory’s advanced imaging detected fast-spinning asteroids in the main belt between Mars and Jupiter—regions where such objects were previously hard to spot—marking a major leap in observing capabilities. Rubin天文台正准备启动其长达十年的空间和时间遗产调查。 The Rubin Observatory is preparing to launch its decade-long Legacy Survey of Space and Time.
