Where do comets with those long tails hide when they aren't coming to visit us? Little Panda tells you: The vast majority of comets live quietly in the 'super deep-freeze' at the very edge of the solar system—places called the 'Kuiper Belt' and the even more distant 'Oort Cloud.' It is freezing cold there all year round, keeping countless ancient small celestial bodies frozen solid. They pack tightly together like little ice cream cubes chilled inside a giant refrigerator. Sometimes, a tiny gravity tug from nearby large planets gives one of these comets a little push, sending it on a long, lonely road trip across the solar system. Scientists absolutely love studying comets because their bodies seal up primitive materials from 4.6 billion years ago when the solar system was just born. Investigating them is just like unlocking a magical 'cosmic time capsule'!
