Small cosmic travelers with big stories — leftovers from the making of our solar system.
Asteroids and comets are ancient space rocks — remnants of the early solar system that never became planets. Though small compared to planets and stars, they carry clues about the formation of Earth, water, and possibly even life.
Some drift quietly. Others streak across the night as meteors — or visit us in spectacular returns like Halley's Comet.
