what is the diameter of Halley's comet how bright is Halley's comet and some more junk
The new comet, Hale-Bop, was very bright when it came past about 6 years ago.
Halley's Comet takes about 76 years to complete one orbit around the Sun. It was last seen in the inner Solar System in 1986 and is predicted to return in 2061.
Edmund Halley was the fellow who first realized that the historical accounts of comets seemed to show that they were not solitary events; that they came back into view on a regular schedule. Examining the records, Halley calculated the probable orbit of the comet and concluded that the comet of 1682 was probably the same comet that had been seen in 1607 and before that in 1531. Halley predicted that the comet would once again be visible in 1758. When it was observed in December, 1758, it was dubbed "Halley's Comet", a title it retains.To astronomers, Halley's Comet is called "1P/Halley"; the 1P indicates that in the catalog of comets, this is the first entry and that it is "Periodic".
Halley's Comet has a nucleus (solid center) estimated to be about 9 miles (15 kilometers) wide. The most recently verified sighting of Halley's Comet was in 1986.
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.
The last sighting of Halley's Comet was in 1986. It is expected to return in 2061.
It is believed that Mark Twain (aka Samuel Clemens) was born the same month as the passing of Halley's comet in November 1835. Halley's Comet passed on November 10th 1835 and Twain was born November 30th 1835. Twain vowed he would "go out"with the passing of the comet, as it passes in 75 year cycles. Halley's comet passed again April 20th 1910, Twain passed April 21st 1910.

Halley's comet was named after Edmond Halley, the English astronomer who first discovered that it was a periodic object in 1705. The comet had been seen and recorded as early as 240 B.C., but no one realized it was the same comet in the sky before Halley.
Halley's Comet is expected to return to pass Earth in 2061. It follows a periodic orbit that brings it back approximately every 75-76 years.

Every 76 years or so. The precise orbit is difficult to calculate precisely because the irregular thrust given off by escaping gasses, and by the variance of Halley's passes by the outer planets.
