Interesting fact: Comets are often called 'dirty snowballs' because they are made of ice, dust, and rocky material.
The answer: Comets typically weigh between a few billion to several trillion kilograms, depending on their size and composition. For example, Comet 67P/Churyumov–Gerasimenko weighs about 10 billion kilograms.
Comets are icy bodies that orbit the Sun, developing glowing comas and tails when near the Sun due to sublimation of ice. Their mass varies widely; smaller comets may weigh a few billion kilograms, while larger ones can reach trillions. Their composition of ice and dust makes them less dense than asteroids. Studying comet mass helps understand the early solar system and potential impact threats.
