Comets become visible only when they are near the sun

Answer 1

yes , Comets become visible only when they are near the sun.

Explanation:

Comets are very large in size but they appear to be small as they are far from our Earth. They are large dirt particles . They can't emit their own light so when they come near to sun the light falls on comet and they shine. So Comets become visible only when they are near the sun.

Answer 2

$\huge\tt{Answer:-}$

Yes, Comets become visible only when they are near the sun.

$\tt{Reason:-}$

As we know, comets are huge ice stars. They get melted as they get in contact with solar heat (sun's radiation). As a result, gaseous substances form a tail and hence, we can see the comet. They get a huge tail made up of gases and liquids. They are visible to our naked eye in this way.
