SOLAR SYSTEM

Detailed explanation-1: -They range from a few miles to tens of miles wide, but as they orbit closer to the Sun, they heat up and spew gases and dust into a glowing head that can be larger than a planet. This material forms a tail that stretches millions of miles. Comets are cosmic snowballs of frozen gases, rock, and dust that orbit the Sun.

Detailed explanation-2: -The ion tail is made up of ions (surprise!)-mostly CO+, N2+, CO2+. As the comet comes into the inner solar system, the Sun’s radiation heats up the nucleus, “boiling off” and ionizing these gases.

Detailed explanation-3: -The Short Answer: 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 Sun’s heat vaporizes some of the comet’s material, releasing dust particles that were trapped in the ice. A combination of solar radiation pressure and solar wind blow away gas and dust from the comet’s nucleus, forming two separate tails: the ion tail and the dust tail.

Detailed explanation-5: -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.
