SOLAR SYSTEM

Detailed explanation-1: -Comets are cosmic snowballs of frozen gases, rock, and dust that orbit the Sun. When frozen, they are the size of a small town. When a comet’s orbit brings it close to the Sun, it heats up and spews dust and gases into a giant glowing head larger than most planets.

Detailed explanation-2: -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.

Detailed explanation-3: -Comets are large objects made of dust and ice that orbit the Sun. Best known for their long, streaming tails, these ancient objects are leftovers from the formation of the solar system 4.6 billion years ago.

Detailed explanation-4: -The coma of a comet is made largely of water and dust. When a comet approaches the Sun, it warms up. Heat from the Sun changes the comet’s icy materials to gases. The comet releases these gases, forming the coma.

Detailed explanation-5: -As comets move close to the Sun, they develop tails of dust and ionized gas. 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-6: -Comet is an icy cosmic ball which orbits the Sun and while coming closer to Sun releases gases.
