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, the best-known short period comet, returns to the inner solar system every 76 years or so. We aren't yet able to predict to the month when that will happen, and gravitational interactions with the outer planets sometimes alters the orbits of comets.
The next predicted perihelion of Halley's Comet is July 28, 2061.
The comet cycle is 75-76 years. It last appeared in 1986.
the next confirmed blue moon will be on august 21 2012 . it has not let been confirmed that there will a blue moon in may 2012
nobody knows when.
"Falling Stars" can happen at ANY time; including right now. There are several "meteor showers", which do happen on regular dates. They are named for the constellation from which they appear to originate. Meteor showers occur whenever the Earth passes through, or near, the path of an old comet. It is likely that the meteors we see are ancient comet dust striking the Earth. The next is apparently the Lyrids, on April 20.
This is estimated to be in 70,000 years, according to Wikipedia.
It is impossible to predict where the next tornado will occur.
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.
It can be seen every 75-76 years. The next predicted perihelion of Halley's Comet will be 28 July 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.
Comet Halley was last visible to us in 1997. It only appears about every 75 or 76 years. It is predicted to be visible again on the 28th July 2061.
halleys comet will return in 2061.
That is Halley's comet, named after English astronomer Edmond Halley,
HayleysComet will come about 2061!!!!!!!!!!!! It last came in 1986.
As of May 20, 2014 the next comet that will be coming by the Earth is Comet Faye at the end of May 2014. In June 2014, Comet Brooks 2 will be passing the Earth.
This does occur sometimes, with periods. The skipped month is not always fully understood, but there can be a number of reasons behind it (most of them nonpathologic).
Halley's Comet or Comet Halley (officially designated 1P/Halley) is the most famous of theperiodic comets and can currently be seen every 75--76 years. Halley's Comet last appeared in the inner Solar System in 1986, and will next appear in mid-2061.
