Description
Halley-type comets aren’t solid “snowballs.” Inside the nucleus is a packed mix of rock, dust, and ice—like a frozen rubble pile. When a comet swings into the inner solar system, sunlight heats it up, jets erupt, fractures spread, and the nucleus can begin to shed countless fragments. Those fragments can range from pebbles to city-destroying, Tunguska-sized objects, turning one comet into a long-lasting debris stream. This explainer shows a realistic cutaway of a Halley-type comet nucleus and what happens as it starts to break apart near the Sun. Randall Carlson presents Cosmography101
