Explanation:
Detailed explanation-1: -The first, and the only part that is constantly visible, is the comet nucleus. This is the central part of the comet and the only part that is solid. It consists of varying proportions of rock, dust, ice and gas that give comets their “dirty snowball” reputation.
Detailed explanation-2: -Physical structure. A comet consists of five distinct parts: a nucleus, a coma (constantly escaping atmosphere), an extended hydrogen halo, a plasma (type I) tail, and a dust (type II) tail. Associated with the dust is a trail of large dust particles distributed in the comet’s orbit.
