Detailed explanation-1: -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-2: -Comets have two main tails, a dust tail and a plasma tail. The dust tail appears whitish-yellow because it is made up of tiny particles-about the size of particles of smoke-that reflect sunlight. Dust tails are typically between 1 and 10 million kilometers (about 600, 000 to 6 million miles) long.
Detailed explanation-3: -A comet is an icy, small Solar System body that warms and begins to release gases when passing close to the Sun, a process called outgassing.
Detailed explanation-4: -A comet is an icy, rocky mass that has passed close by the Sun within our Solar System, and has thus warmed up and begun to release gases, causing a visible atmosphere-and sometimes a ‘tail’-to form.
