Comets Growing Old

TNRTB Archive - Retained for reference information

A variety of studies show that solar system comets have aged. As many observations confirm, thermal heating from passing stars, collisions among comets, interactions with the interstellar medium, and radiation damage all have significantly altered the top one or two meters of comets’ surfaces. These studies establish that solar system comets are about four billion years old and that surface samples of meteorites and comets do not reflect the interplanetary delivery of prebiotics to Earth.
