SOLAR SYSTEM

Detailed explanation-1: -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-2: -When comets come near the Sun, their tails become visible because heat from the Sun vaporizes some of the icy nucleus or head and sunlight reflects from the vapor. Solar wind pushes the vapor in a direction away from the Sun to form the comet’s tail.

Detailed explanation-3: -Asteroids, which are mostly rocky, do not usually form tails when they approach the Sun. Comets, however, are a mix of ice and rock, and typically do form tails as the Sun vaporizes their ice, blasting material off their surfaces and leaving a trail along their orbits.

Detailed explanation-4: -properties of comets The dust tail forms from those dust particles and is blown back by solar radiation pressure to form a long curving tail that is typically white or yellow in colour.

Detailed explanation-5: -A comet is a heavenly body with a long glowing tail of light behind it. It is also called ‘tailed star’. Comets also are members of the sun’s family like other heavenly bodies.
