Every 76 years, Halley’s comet passes by the Earth and can be seen in the sky. In 1835, one of the years in which this phenomenon occurred, Mark Twain was born. Moreover, the writer predicted that his death would occur in the same year when the comet passed by again.

“The Almighty has said, no doubt, ’Now here are these two unaccountable freaks; they came in together, they must go out together,’” he said. Most surprisingly, he was not wrong, he died a day after the comet reached its closest point to Earth.
