A comet is a celestial object that consists of a nucleus made of ice, dust, and rocky material. A comet is like a “dirty snowball” traveling through space. When a comet approaches the Sun, the heat causes the ice to vaporize, creating a glowing coma (a cloud of gas and dust) around the nucleus.
Comets are fascinating cosmic travelers that originate from the outer regions of the solar system and provide valuable insights into the early formation of our universe.
