SOLAR SYSTEM

Detailed explanation-1: -When the comet comes near the sun, some of its ice turns into gas. This gas and loose dust, freed from ice create a long illuminating tail.

Detailed explanation-2: -Tail of comets appears as a Tyndall cone because of the scattering of light by the tiny solid particles that are left behind by the comet in its route. We can define the Tyndall effect as the phenomenon of scattering of particles of light in its path.

Detailed explanation-3: -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.
