Hally'sComet
There is no relationship whatsoever between Earth's moon and any comet.
The name of the comet seen in 1986 is Halley's Comet. You can see it every 75-76 years, and is the only short period comet that is clearly visible to the naked eye from earth, and thus the only naked-eye comet that might appear twice in a human lifetime.
The next notable comet scheduled to pass by Earth is Comet Leonard, which is expected to be visible in December 2021. It will be the brightest comet of the year and should be observable with binoculars or a small telescope from dark sky locations. Keep an eye out for updates from astronomers as the date approaches for the best viewing opportunities.

EARTH
Yes, they are visible. Every year the earth passes through the orbits of old comets (or similar objects) and these result in meteor showers. Amongst the better known ones, visible in the Northern hemisphere, are the Perseids in mid August from the comet Swift-Tuttle and the Leonids in mid November from the comet Tempel-Tuttle..
