Extensive monitoring by NASA’s Sentry system and ESA’s risk lists shows no near-Earth objects with meaningful impact probability through the end of 2026, underpinning the 94.5% market-implied odds against a 10-kiloton-or-greater meteor strike. Ongoing sky surveys have cataloged thousands of NEOs this year, with all recent close approaches safely missing Earth by multiple lunar distances and predicted 2026 impacts limited to sub-10-meter objects that disintegrate harmlessly. Historical detection rates and model consensus indicate large, undetected impactors capable of 10 kt yields are exceedingly rare on annual timescales. Residual uncertainty stems from objects on very short observational arcs or potential non-gravitational perturbations, though follow-up observations typically retire such risks quickly.
如果在 1月1日 至 2026年12月31日, 23:59 ET 期间,有天然流星体(火流星)在地球大气层中爆炸,且总撞击能量大于或等于 10 千吨 TNT 当量,本市场将判定为“是”。否则,此市场将判定为“否”。 该物体必须被归类为天然流星体;涉及人造物体或再入飞行器的事件不符合条件。 主要判定来源为 NASA JPL Fireball and Bolide Data 存储库:https://cneos.jpl.nasa.gov/fireballs/。用于确定撞击能量的相关字段是“Impact Energy (kt)”列。如果该数据集在 2027年2月28日 前尚未更新以纳入所有相关日期,或者 NASA JPL Fireball and Bolide Data 存储库永久无法访问,则本市场可根据可信来源的共识进行判定,包括欧洲航天局(ESA)、国际小行星预警网(IAWN)、美国国防部,或有关科学共识的可信报道,例如 NASA 新闻稿。
