一颗重达7,宽约6英尺的流星在2026年3月17日从威斯康辛州到马里兰州形成了一颗明亮的火球,然后在美国东北部破裂. 美国国家航空航天局证实它以高达16万英里的速度穿过上层大气超过34英里,但没有发现碎片. A 7-ton meteor, about 6 feet wide, created a bright fireball visible from Wisconsin to Maryland on March 17, 2026, before breaking apart over the northeastern U.S. NASA confirmed it traveled more than 34 miles through the upper atmosphere at speeds up to 160,000 mph, but no fragments have been found. 虽然大部分都没有被注意到, 但每天有成千上万的火球石进入地球大气层. Such fireballs—meteors brighter than Venus—are common, with thousands entering Earth’s atmosphere daily, though most go unnoticed. 现在,每天有100多份报告. In 2026, ten fireballs have drawn over 100 reports each, averaging nearly one per week. 科学家鼓励公众观测, 帮助研究. Scientists encourage public sightings to aid research.
