Answer:
A.) Meteorite: A meteoroid, especially one that has hit Earth's surface. Asteroid: A rocky object that orbits the sun and has an average size between a meteoroid and a planet. Comet: An object made mostly of ice and dust, often with a gas halo and tail, that sometimes orbits the sun.
B.) Meteoroids are lumps of rock or iron that orbit the sun, just as planets, asteroids, and comets do. ... They orbit the sun among the rocky inner planets, as well as the gas giants that make up the outer planets.
C.)A comet while going on elliptical orbit around the Sun has constant angular momentum due to no external torque and total energy due to Law of conservation of energy at all locations but other quantities vary with locations.
D.)The tail actually has twin pieces, a gas tail and a dust tail, that can extend for millions of kilometers from the comet nucleus as it travels around the Sun. As the comet gets very close to the Sun, small pieces of dust, rock grains, and ice are left behind as a trail of meteoroids.
