Question

What happens as a comet approaches and moves away from the sun?

As a comet approaches towards the sun it becomes warm. Then as it moves away from the sun, it forms a glowing tail and extends over 100 million km.

Please tell me if this is correct, thanks

Answer 1

Farthest from the sun, the comet would have no tail. The tail would become prominent <I>closer</I> to the sun, because the solar radiation vaporizes parts of the comet. The tail always points away from the sun.

I hope this helps.
