Space comets are cosmic objects made up of ice, dust, and gas. When they approach the sun, the heat causes the ice to vaporize, forming a glowing tail. They originate from the distant Oort Cloud or Kuiper Belt, and their orbits are highly eccentric and unpredictable, unlike the more stable orbits of planets. Comets are often seen as “wildcards” in the solar system and can appear unexpectedly, creating a spectacular sight as they streak across the sky.
