Question

Quizplus · Accepted Answer

Asteroids are rocky and metallic remnants left over from the formation of the solar system, similar in composition to pieces of terrestrial planets. Comets, on the other hand, are made up of ice, dust, and rock, and their densities are much lower than that of asteroids. The Sun is a completely different entity, made up of mostly hydrogen and helium gases. Jovian moons may have similar densities, but their compositions differ greatly due to their formation in the gas and ice-rich outer solar system. Kuiper Belt objects like Pluto are also icy and have a different composition from asteroids. Asteroids are made up of rock and metal, similar to the composition of terrestrial (rocky) planets like Earth. Therefore, they resemble pieces of terrestrial planets in composition and density.
