SOLAR SYSTEM

Detailed explanation-1: -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-2: -When far from the sun, a comet is like a stone rolling around the universe. But when it approaches the sun, the heat evaporates the comet’s gases, causing it to emit dust and microparticles (electrons and ions). These materials form a tail whose flow is affected by the sun’s radiation pressure.

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.

Detailed explanation-4: -Scientists sometimes call comets dirty snowballs or snowy dirtballs, depending on whether they contain more ice material or rocky debris according to NASA. Related: How to view and photograph comets.
