Halley’s comet returns to Earth’s neighborhood every 75 years — so depending on how old you are when you first see it, you might be able to see it twice.

Halley’s comet last approached Earth in 1986. Its next approach is scheduled for 2061.

For any given spot on Earth, a total solar eclipse will be visible once every hundred years or so.
