The sequence 1531, 1607, 1682, 1758, 1835, 1910, 1986, 2062 represents the years in which Halley’s Comet appears (or in the case of 2062, will appear).
The life of Mark Twain, the pen name of Samuel Clemens, is intertwined with the comet in a unique way. Mark Twain was born (1835) and died (1910) during Halley’s comet years. What is even more remarkable is that Clemens predicted the year of his death. In 1909, he said:
“I came in with Halley’s Comet in 1835. It is coming again next year, and I expect to go out with it. It will be the greatest disappointment of my life if I don’t go out with Halley’s Comet. The Almighty has said, no doubt: ‘Now here are these two unaccountable freaks; they came in together, they must go out together.”
True to his prediction, he died of a heart attack one day after Halley’s Comet appeared at its brightest in 1910.
