Comet tail - Wikipedia
A comet tail and coma are visible features of a comet when they are illuminated by the Sun and may become visible from Earth when a comet passes through the inner Solar System. As a comet approaches the inner Solar System, solar radiation causes the volatile materials within the comet to vaporize and stream out of the nucleus , carrying dust ...

Sep 12, 2024 · What is a comets tail? A comet’s tail consists of two distinct parts: the dust tail and plasma tail. The dust tail contains small particles of ice and dust released by the comet’s nucleus. The plasma tail forms from ionized gas and charged particles.
Comets: Facts - NASA Science
Comets actually have two tails – a dust tail and an ion (gas) tail. Most comets travel a safe distance from the Sun. For example, Halley's comet gets no closer than 55 million miles (89 million kilometers).
