Variations in the orbit of comets in the outer solar system can cause periodic comets to appear earlier or later than anticipated. We expect Halley's Comet to appear again in 2061. I don't believe that it would be accurate to narrow it down much further.
Further, the telescopes of 2060 are likely to be orders of magnitude better than the current Hubble and Spitzer space telescopes. It is possible that astronomers 50 years from now will be able to detect the comet well in advance of it becoming a naked-eye object.
Halley's Comet is a well-known comet that orbits the Sun approximately every 76 years. It last appeared in 1986 and will next be visible from Earth in 2061.
The next visible comet that is expected to be visible to the naked eye is Comet Leonard in late 2021.
The next blue moon in May will occur on May 18, 2022.
Halley's comet is not predicted to hit Earth in the foreseeable future. The next time it will be visible from Earth is in 2061.
This is estimated to be in 70,000 years, according to Wikipedia.
2061
Halley's Comet is a well-known comet that orbits the Sun approximately every 76 years. It last appeared in 1986 and will next be visible from Earth in 2061.
Halley's Comet is a Short Period Comet. It is actually the brightest known short period comet, one of the main reasons for it's popularity. It is visible from Earth once every 75–76 years. The last being in 1986 and the next being in 2061.
Halley's Comet has never been 10 miles above Earth. It is always millions of miles from us, even when closest to us. It was last visible from Earth in 1986. It will next be visible in 2061.
Halley's Comet was last visible from Earth in 1986. Its next predicted return is in 2061.
Halley's Comet was a periodic comet; it returns to the inner system every 76 years. Hale-Bopp is a very long-period comet; it may have been last seen in 2215 BC. That may have been Hale-Bopp's first approach to the Sun; its orbit was likely altered by close brushes with Jupiter then, and again during its last pass in 1997. Hale-Bopp's next appearance may be in or around the year 4530 AD.
That is Halley's comet, named after English astronomer Edmond Halley,
Halley's Comet was last visible from Earth in 1986. It orbits the Sun roughly every 76 years, so its next predicted return is around 2061.
It can be seen every 75-76 years. The next predicted perihelion of Halley's Comet will be 28 July 2061.
halleys comet will return in 2061.
It's unclear what you mean by "hades comet." If you are referring to a comet named Hades, there is no specific comet with that name. If you meant Halley's Comet, it will next be visible from Earth in 2061.
The next visible comet that is expected to be visible to the naked eye is Comet Leonard in late 2021.
