This question was posted on September 3, 2011, so the year 2010 is already in the history books. I don't recall any especially impressive comets in 2010.
But basically, there are several new, never-before seen comets (or long-period comets last seen during the reign of the Pharaohs, like Hale-Bopp) for which we have no orbital knowledge, that appear each year. Once the comet has been seen three times, we can calculate an orbit, and determine, more or less, where it will be at any future date. But until then, it's a mystery.
Halley's Comet is still orbiting the Sun. It was close to Earth in 1986.
The name of the comet that will pass Earth on August 15, 2011, is the comet Honda.
No. in 1961 the comet was way out in the solar system, the recent close approaches were in 1910 and 1986 - non of there were as close as 10 miles from the nucleus, although Earth did pass through the comets tail in 1910.
i dunnoo... jeez
We expect the only Halley's Comet there is to return to the inner solar system in 2061. That means it'll get close enough to the sun so that we can see it, but we can't tell yet exactly how close to earth it's likely to get.
Haley's Comet, officially known as Halley's Comet, is projected to pass closest to Earth in 2061 on its 76-year orbit cycle. The last time Halley's Comet was visible from Earth was in 1986.
It will be back again in 2061. The 1986 flyby was a bit of a disappointment. Comet Kohoutek in 1973 was much better, but it won't be back for another 75,000 years.
none we hope .
in 2016 .
Halley's Comet is next due to pass by Earth in 2061. It follows a roughly 76-year orbit around the Sun.
The next comet will be Comet Ison which will pass by the earth in 2013. It will be visible with lenses during late summer and will be visible to the naked eye by approximately November.
When they pass close to the sun, the heat creates vapor which becomes a tail
