Every 76 years, but the orbit of a comet is susceptible to gravitational disturbances from nearby masses out toward the other end of its orbit.
11.86 Earth years, or every 4330.6 Earth days
Every Year, but each year is different for each planet: Mercury- 88 Earth Days (.25 Earth Years) Venus- 255 Earth Days (.7 Earth Years) Earth- 365 Earth Days (1 Earth Year) Mars- 687 Earth Days (1.8 Earth Years) Jupiter- 4,346 Earth Days (11.9 Earth Years) Saturn- 10,774 Earth Days (29.5 Earth Years) Uranus- 30,680 Earth Days (84 Earth Years) Neptune- 60,625 Earth Days (165 Earth Years)
The moon is not getting closer but further
The Earth is approximately 4.567 Billion years old (4,567,000,000).There are 365.25 days in a year (hence leap years every 4 years).365.25 x 4,567,000,000 = 1,668,096,750,000.As such the earth is approximately 1.67 trillion days old.
Mars cannot orbit the earth. It orbits the Sun aprox. every 2 Earth years.

Approximately every 76 years 1986 + 76 = 2062
10000 years
About the next 100 years or so.
Halleys comet comes back around every 76 years.
It depends on the comet for example Haleys comet appears about every 95 to 100 years.
75 years
Halley's Comet returns once every 75-76 years.
Halley's comet was first seen in 1577 however it was not recognized as a comet. It was Edmund Halley that discovered it as a comet in 1705.
It takes roughly 75 years for Halley's comet to come by the earth. All comets orbit the sun, but they do not all originate from the same place, which accounts for their paths and how long their individual orbit takes.
commet fish live for 50 or 60 years
What comes past the Earth every 70-75 years?
