What is the difference between a comet and an asteroid?

Indeed, sir, the distinction between a comet and an asteroid lies in their composition and behaviour. A comet is typically composed of ice, dust, and rocky materials, and it often has a tail that becomes visible when it approaches the Sun. This tail forms due to the heat from the Sun causing the comet's surface to sublimate, turning solid into gas, and releasing particles that are pushed by solar wind. An asteroid, on the other hand, is generally made of rock or metal, with little to no ice. They tend to follow more predictable orbits around the Sun and do not usually develop tails unless they come very close to the Sun or are perturbed in their path.
