Beginning about 1950, the accepted astronomers definition of a comet was a "dirty snowball". That's still not bad, but more recent research has revealed that comets have many more solids and "tholins" (very basic organic compounds) than previously thought. Hence, the "improved" definition of a comet today is a "snowy dirtball".
A comet is a celestial body composed of ice, dust, and rock that orbits the Sun. As a comet approaches the Sun, its icy surface vaporizes and releases glowing gases and dust, forming a bright, visible coma and tail that can stretch across millions of kilometers. Comets are known for their spectacular appearance in the night sky and are often referred to as "dirty snowballs."

What is a nucleus of a comet?
The nucleus of a comet is the solid, icy core of the comet. It is composed of a mixture of ice, rock, dust, and organic compounds. As a comet gets closer to the Sun, the heat causes the nucleus to release gas and dust, forming the characteristic coma and tail of the comet.
The tail of a comet is longest when the comet is?
The tail of a comet is longest when the comet is closest to the sun, as the sun's heat causes the comet's icy surface to vaporize, creating a bright glowing tail that streams away from the comet.
What is the definition of a comet head?
The comet head refers to the spherical cluster of dust and gas surrounding the comet's nucleus, which is primarily composed of ice, dust, and organic compounds. As the comet approaches the Sun, the heat causes this material to vaporize and form the comet's characteristic coma or fuzzy halo.
