Here's a breakdown:
* Comet: A celestial body made of ice, dust, and rock.
* Comet tail: A stream of gas and dust that is emitted by a comet as it approaches the Sun. The tail is formed due to the pressure of sunlight and the solar wind pushing away the comet's material.
* Two types of comet tails:
* Dust tail: Composed of small particles of dust, which are reflected sunlight, giving the tail a yellowish or whitish color.
* Ion tail: Composed of ionized gas (atoms that have lost electrons) that are pushed away by the solar wind, giving the tail a bluish color.
It's important to note that comet tails always point away from the Sun, regardless of the comet's direction of travel. This is because the solar wind and sunlight are pushing the material outward.
