  鲁宾天文台在小行星带中发现了一颗 710 米超快小行星

  天文学家发现了小行星 2025 MN45，直径为 710 米，每 1.88 分钟旋转一周。这一发现发生在智利维拉·C·鲁宾天文台的初始测试阶段，甚至在主要任务正式开始之前。该物体因超越了大型小行星已知的物理极限而脱颖而出，尽管旋转速度极高，但并未破碎。 此次观测是利用 2025 年 7 个晚上获得的大约 10 个小时的累积数据进行的。在这么短的时间内，设备捕获了有关太阳系中近 2,000 颗新小行星的信息。 2025 MN45 位于火星和木星之间的主带，由于光变曲线显示其加速旋转而立即引起人们的关注。 测试阶段的惊人发现 该望远镜配备了迄今为止最大的数码相机（3,200 兆像素），可让您快速捕捉天空的详细图像。这种能力使得以前所未有的精度识别远处物体的亮度变化成为可能。...
