They are too difficult to see when they are in the outer solar system.
Heat from the Sun causes ices on the comet to sublimate.
The solar wind erodes the surface of the comet.
The Sun’s gravity pulls material from the surface of the comet.

Explanation / Answer
The reason why comet tails appear only when they move into the inner solar system is that heat from the sun causes ice on the comet to sublimate.
When comets approach closer to the sun, the ice will begin to sublimate in a process known as Outgassing, this process mets the ice and produces a visible tail.
