Comets are made mostly of ice.
I am pretty sure that comets are lighter than moons but it depends on the comet
Asteroids and comets are both celestial bodies that orbit the Sun. They are remnants from the formation of the solar system and are composed of rock, metals, and other materials. However, comets are distinguished by their icy composition and tail of gas and dust when they approach the Sun.
Its composition is usually rocky or metallic.

Comets and comet composition
Asteroids are rocky, airless remnants from the early formation of the solar system, primarily found in the asteroid belt between Mars and Jupiter. Comets, on the other hand, are composed of ice, dust, and rocky material and originate from the outer regions of the solar system, such as the Kuiper Belt and Oort Cloud. When comets approach the Sun, they develop a glowing coma and tail due to the sublimation of their icy components. Thus, the main differences lie in their composition and behavior when near the Sun.
No, asteroids and comets are classified based on their characteristics and composition. Asteroids are rocky and metallic bodies that orbit the Sun, while comets are icy bodies that develop a fuzzy atmosphere and tail when they get close to the Sun. While some objects can exhibit characteristics of both, they are still considered either an asteroid or a comet based on their main features.

The rocky, gritty material in a cometary nucleus is probably much like a solid asteroid in chemical profile. But most asteroids are solid, barren rock - the comet has a large percentage of ices in it.
Asteroid Comets are icy conglomerations of material, so cannot be called a "rocky object".
