When will Hale-Bopp Comet return within Earth's view?
AnswerThe Hale-Bopp comet is now beyond the orbit of Uranus but is expected to still be visible by large telescopes until about 2020. After then, it is not expected to make a return until the year 4534.
Halleyâ??s Comet is a periodic comet and returns to earth at roughly every 75 years as predicted by Edmond Halley. Who happened to notice the pattern but was unable to see its return in 1758. In 1910 the comet was especially fantastic, having passed Earth by at about 13.9 million miles, and was photographed for the first time. The return of the comet in 1986 was met by a number of nationâ??s satellites. This fleet…
Halley's Comet is a short-period comet; we can predict that it will return to the inner solar system within our lifetimes, and several times in recent history. Most other comets are either long-period and will not return for centuries, or will never again be visible. Sometimes it is very bright; sometimes it is a "fizzle". It is this element of reassuringly-predictable repeating mystery that makes it noteworthy.
Halley's Comet was named after Edmond Halley, after he predicted the return of a comet known since 240 BC. He published Synopsis Astronomia Cometicae, which stated his belief that the comet sightings of 1456, 1531, 1607, and 1682 were related to the same comet, which he predicted would return in 1758 His predictions were spot on, although he did not live long enough to witness the return of the comet.
Halley's comet got its name from Sir Edmund Halley who, using Newton's laws of motion, predicted that the comet seen in 1531, 1607, and 1682 would return in 1758. Unfortunately, Halley died before seeing the comet return, but when it returned just as he had predicted, the comet was named in his honour by French astronomer Nicolas Louis de Lacaille in 1759. Halley's Comet was named for Edmond Halley, the English astronomer who identified it…
It rather depends on the path of the comet. Some comets (such as Encke's comet) return in as little as 20 years - others might not return to our solar system for centuries (Comet McNaught has an orbital period of over 92,000 years !) It's possible to see at least one comet per year if the weather conditions ar favourable.
No. Halley's Comet is visible for several days when it does appear- about every 75 years. But Einstein was born about 39 years after the visit of the comet- and died 31 years before it's return. However, Samuel Clemens (Mark Twain) was born the year of the appearance of the comet, and was convinced he would die at its return.
