Younger Dryas impact theory involves comet fragmentation

Younger Dryas impact theory involves comet fragmentation. Younger Dryas impact event occurred approximately 12,800 years ago Multiple theories exist: comet impact, solar flare, or combined event Microspherules and KT boundary provide evidence of impacts

A comet likely grazed the Sun ~12,800 years ago, ejected a massive flare, fragmented, and struck Earth in multiple locations. Evidence includes microspherules and similarities to the KT boundary. Fragments keep returning—the Taurid Stream meteor still produces thousands of hourly sightings, with the last major piece arriving around AD 1280, possibly inspiring King Arthur legends.

Key Facts

• Younger Dryas impact event occurred approximately 12,800 years ago
• Multiple theories exist: comet impact, solar flare, or combined event
• Microspherules and KT boundary provide evidence of impacts
• A comet likely came close to the Sun which ejected a major flare, fragmenting the comet and causing multiple impacts on Earth
• Fragments continue returning to Earth because they maintain the same orbital speed
• The Tarid Stream meteor recorded thousands of sightings per hour
• The last Younger Dryas fragment arrived around AD 1280, possibly connected to the King Arthur legend
