Scientists have discovered that comets emerge as deep in space as Saturn’s orbit.

When the first comets are seen near Earth, their glowing tails of ionized gas scatter the observers, but with each return, they become smaller.

Comets are ice balls. Therefore, astronomers believe that these objects are less likely to return to Earth because they released more ice and gas when they first visited the solar system inside. The comets melt and decrease because of the heat of the sun, the mind goes away, so when they return, there is less left over for release, and therefore a faint coma.
