I WONDER - What Are The Different Parts of a Comet?

The video tutorial explains the main components of a comet: the nucleus, coma, hydrogen envelope, and tails. The nucleus is the solid core made of dust, rock, and frozen gases. The coma forms when a comet approaches the sun, causing the icy nucleus to release gas and dust. The hydrogen envelope surrounds the coma. Comets have two tails, an iron tail and a dust tail, which lengthen as they near the sun.
