The term 'Celestial Streaker' is a combination of two words, 'METEOR' and 'COMET'. A METEOR is a small piece of rock or dust that enters the Earth's atmosphere and burns up, creating a streak of light in the sky. A COMET is a celestial body made up of ice, dust, and gas that orbits the sun and has a visible coma and tail. Together, these two words form the term 'Celestial Streaker', which is used to describe a bright streak of light in the night sky caused by either a METEOR or a COMET.
