A nucleus and a tail
The three main parts of a comet are the nucleus (solid core made of ice and dust), coma (gaseous envelope surrounding the nucleus), and tails (two types, ion tail composed of ionized gas and dust tail made of dust particles).

The coma, the nucleus, and the tail are the parts of a comet after the tail has formed.

A Comet
What DO comet tails originate from? They are formed when the sun causes gas and dust to leave the comet, and are then swept away by solar winds. This is why that no matter which direction a comet is traveling, it's tail is always pointed awY from the sun.

The three main parts of a comet that are always present are the nucleus (composed of ice, gas, and dust), the coma (a cloud of gas and dust surrounding the nucleus), and the tail (formed when the coma is blown away by the solar wind).
