In which way are a comet and an asteroid most different?
A
size
B
speed
C
how they are studied
D
what they are made of
Explanation: 

Detailed explanation-1: -A comet also orbits the Sun, but unlike an asteroid, it’s composed of ice and dust. So, when a comet gets close to the Sun, its ice and dust content start to vaporize. So, when seen in a telescope, a comet appears fuzzy and/or has a tail.

Detailed explanation-2: -What is the difference between asteroids and comets? Comets are visible without a telescope. Asteroids are mostly rock and rock pieces, comets are composed of ice, gases, and dust.

Detailed explanation-3: -The main difference between comet and meteor is that a comet is a cosmic object made of ice, gases, rock and dust that orbits the Sun while a meteor is a meteoroid that has entered the Earth’s atmosphere. Meteors, meteoroids, meteorites, and asteroids are all objects that originate in the space.

Detailed explanation-4: -The S-types ("stony") are made up of silicate materials and nickel-iron. The M-types are metallic (nickel-iron). The asteroids’ compositional differences are related to how far from the Sun they formed.

Detailed explanation-5: -Comets are frozen leftovers from the formation of the solar system composed of dust, rock, and ices. They range from a few miles to tens of miles wide, but as they orbit closer to the Sun, they heat up and spew gases and dust into a glowing head that can be larger than a planet.
