KIDS TRIVIA

Detailed explanation-1: -These compounds include water, ammonia, methane, carbon monoxide, and smaller amounts of other, more complex compounds. The dust in comets is composed of silicates and some metals. Recently, ethane gas was detected in comet C/1996 B2 (Hyakutake).

Detailed explanation-2: -At the heart of every comet is a solid, frozen core called the nucleus. This ball of dust and ice is usually less than 10 miles (16 kilometers) across – about the size of a small town.

Detailed explanation-3: -Every comet has a nucleus, a stable, porous central mass of ice, gas, and dust that if often between 1 and 10 kilometers (0.6 to 6 miles) in size. The ice is made of varying amounts of water, carbon dioxide, ammonia, and methane. The dust may contain hydrogen, oxygen, carbon, nitrogen, silica, and some metals.

Detailed explanation-4: -Asteroids are solid, rocky and irregular bodies that are the rocky remnants of the protoplanetary disk of dust and gas that formed around our young sun over 4.5 billion years ago. Much of the disk coalesced to form the planets, but some of the debris remained.
