It duly did, though he was dead by then and it was actually the last few days of 1758 before it was observed.Īstronomy got a new class of object that orbited the Sun and historians had away to assign precise dates to historical sightings of a “great comet.” But the 1910 visit of Halley’s Comet was different because scientists warned that the comet could end life on Earth. The comet reappeared in 1835 and again in 1910. He knew of “great comet” sightings in 15, saw the comet that would later bear his name in 1682, worked that its orbit in 1705, and predicted that it would return in 1758. When the comet arrived on schedule, it became known as Halley’s Comet, although Edmond Halley didn’t live long enough to see his prediction come true. The comet, officially called 1P/Halley, is named after English. It was Edmond Halley who (in 1705) was able to deduce that various historic comet sightings were in fact all of a single comet. It approaches the Sun every 75-76 years and its visits may have been recorded as early as 467 BC. It was last here in 1986, and it is projected to return in 2061. Halleys comet is probably the most well known of all the comets. As a periodic comet, it returns to Earth’s vicinity about every 75 years, making it possible for a person to see it twice in their lifetime. He calculated that the “great comet” that kept on being seen every 75 years was, in fact, the same object. Halley’s Comet is arguably the most famous comet in history.
