Meteorite that landed in Cape Cod was a ‘lone wolf’ from the outer solar system, scientists find
AI-summarised brief · reviewed before publication
On May 30, 2026, a bright daytime bolide streaked over Cape Cod Bay, producing a sonic boom heard across the northeastern United States. A multinational team led by Juha Vierinen combined data from MIT’s SIMONe radar, weather radars, infrasound stations and dash‑cam footage to reconstruct the meteoroid’s trajectory and origin. Radar head‑echoes captured the object between 56 mi and 44 mi altitude, while a trail echo persisted to 20 mi, where the rock fragmented with an explosive force equivalent to 500 tons of TNT. The total impact energy was about 1.1 kilotons, placing the event among the most energetic bolides recorded in recent years. Analysis traced the meteoroid to a small asteroid nudged by Jupiter onto a comet‑like orbit, classifying it as a “lone wolf” from the outer solar system.
