曼哈顿大小的彗星将在2025年10月底安全地通过火星附近,提供了罕见的科学机会。 A Manhattan-sized comet will safely pass near Mars in late October 2025, offering a rare science opportunity.

据哈佛天体物理学家Avi Loeb说,大约在2025年10月底,曼哈顿大小的一颗彗星预计将在火星附近通过。 A comet about the size of Manhattan is expected to pass near Mars in late October 2025, according to Harvard astrophysicist Avi Loeb. 该物体直径约1.5公里,在火星约100万公里内接近,不会对行星或地球造成任何威胁。 The object, roughly 1.5 kilometers in diameter, will approach within about 1 million kilometers of Mars, posing no threat to the planet or Earth. Loeb称飞行是研究一颗大型彗星的构成和轨迹的难得的科学机会,美国航天局和其他机构利用轨道器和望远镜对事件进行监测。 Loeb called the flyby a rare scientific opportunity to study a large comet’s composition and trajectory, with NASA and other agencies monitoring the event using orbiters and telescopes. 彗星的起源不确定,但很可能来自外太阳系。 The comet’s origin is uncertain but likely from the outer solar system.
