Yes, it is possible for a comet to be visible from Earth more than once if it has a return orbit. Some comets have orbital periods that bring them back around and make them visible multiple times in a human lifetime.
Halley's Comet was seen in April 1066, just before the Battle of Hastings in October of that year. It was considered an omen by many, including the Anglo-Saxons and the Normans.
Approximately every 76 years 1986 + 76 = 2062
Comets don't or it the earth, they are in long irregular orbits around the sun. These orbits can range from a few years to thousands of years.
Yes, there are many comets other than Halley's comet. Comets are icy bodies that orbit the Sun and often have elongated orbits that bring them close to the Sun. Some well-known comets include Hale-Bopp, Comet NEOWISE, and Comet Lovejoy.
i think it comes past the earth every 76 years.
It doesn't rotate around earth, but around the sun. This happens every 75-76 years on average.
That is completely unpredictable at this time. Best can be said is probably not this week.
