Comets reflect light from the sun. This is the same way you see the moon glowing. When a comet's orbit nears the Sun it starts to warm up since they are usually black in colour. Water vapour sublimes from the surface of this 'dirty snowball' and forms a cloud of ice crystals known as the 'Coma'. It is this white cloud that reflects sunlight and makes it visible to us.

What are 3 parts of a comet?
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).
