Halley's Comet
Halley’s (pronounced H-ah-lee) Comet is a comet that is only seen from Earth every 75-76 years, and is the only comet that can be seen from the naked human eye. It is also the only comet that can be seen twice in one lifetime. Haley's Comet is the most known out of all of the short period comets. The next time that Halley’s Comet is supposed to able to be seen on Earth is (approximately) mid 2061. The last Halley’s Comet was in 1986.
Halley's comet got its name from Sir Edmund Halley who predicted that the comet would have been seen in 1531, 1607, and 1682 and also would return in 1758. He predicted these dates by using Isaac Newton's Law of Motion. Sir Edmund Halley died before he got to see the comet again, but in 1759 Nicolas Louis de Lacaille named the comet after Sir Edmund Halley in honor of his discoveries.
The comet itself is said to be around 4.6 billion years old, and humans on Earth have been watching it since approximately 240 BC. In 1910, many people believed that Earth would fall into the comet’s tail, and the world would end. In the tail of Halley’s Comet, there is a toxic gas called Cyanogen, that could have possibly wiped out all life on Earth. May 19th had passed, and fortunately nobody died because of the comet except for 16-year-old Amy Hopkins, who fell off her roof while watching the comet with some of her friends.
