Cometary science studies the composition, structure, and behavior of comets, which are icy bodies that originate from the outer regions of the solar system. Understanding comets helps scientists learn about the early solar system and the formation of planetary bodies.
Long-period comets are comets that have orbital periods greater than 200 years. They originate from the Oort Cloud, a distant region of icy bodies surrounding the solar system, and can take thousands of years to complete one orbit around the Sun.
Comets are icy celestial bodies that originate from the outer regions of the solar system. They are composed of ice, dust, and rocky material, and when they approach the Sun, they develop a glowing coma and tail due to the sublimation of their icy components.
