Halley's Comet By Ravi
Transcript of Halley's Comet By Ravi
2. In ancient times a comet signified bad luck. During the Norman invasion in 1066, as Halley's Comet appeared from seemingly nowhere, one of King Harold's servants told him that this "comet star" may be a sign of God's wrath of King Harold unrightfully claiming the English throne.
4. Halley's Comet is darker than coal, and reflects only 4% of the sunlight it receives. It only shines brightly when it nears the Sun and releases a vapour of shiny ice.
5. American writer Mark Twain was born on November 30th 1835, two weeks after an appearance of Halley's Comet's. In his biography, he stated that he was born with Halley's Comet, and is likely to die with it. Mark Twain died on April 21st 1910 - the day after Halley's Comet reappeared. Mad facts!
