Comets
Comets are icy celestial bodies that develop visible tails as they approach the Sun, composed of ice, dust, and rock, and have historically inspired both scientific study and cultural significance.
Developing spectacular glowing tails stretching millions of miles as solar heat vaporizes their icy surfaces, these ancient celestial travelers have captivated and sometimes terrified human observers throughout recorded history.
Composed of Ice, Dust, and Rock
Comets are composed primarily of ice, dust, and rock, often described as "dirty snowballs" traveling through the solar system on often highly elliptical orbits.
Developing Dramatic Tails
As comets approach the Sun, solar heat causes their icy material to vaporize, creating dramatic glowing tails that can stretch for millions of miles.
Historical and Cultural Significance
Comets have held significant historical and cultural importance, often interpreted by ancient civilizations as omens, with Halley's Comet representing one of the most famous examples.
Providing Clues About the Early Solar System
Scientists study comets for clues about the early solar system's formation, since their composition has remained relatively unchanged since the solar system's earliest history.
