 Glossary of astronomical terms
Note that the true comet nucleus is rarely, if ever, directly observed from the earth because of the large amount of gas and dust that is ever-present in the inner coma close to the nucleus, serving to hide the true nucleus' surface.
Thus, a 7th-magnitude comet is much harder to see than a 7th-magnitude star -- the latter having all its light in a pinpoint, and the former having the same amount of light spread out over a large area (imagine defocussing a 7th-magnitude star to the size of a diffuse comet).
Typically, however, when comets become very bright, their apparent coma sizes shrink so that the majority of visible light is in a small, intense core of the comet's head (and the comet may appear starlike with a tail emanating from the comet's head).

 Comet/Jupiter Collision FAQ - Pre-Impact   (Site not responding. Last check: 2007-11-06)
Comet Shoemaker-Levy 9 (1993e) was the ninth short-period comet discovered by Eugene and Carolyn Shoemaker and David H. Levy and was first identified on photographs taken on the night of 24 March 1993.
Only two comets have ever been known to orbit a planet (Jupiter in both cases), and this was inferred in both cases by extrapolating their motion backwards to a time before they were discovered.
Images of the comet taken with the Hubble Space Telescope in July 1993 indicate that the fragments are 3-4 km in diameter (3-4 km is an upper limit based on their brightness; the fragments have visual magnitudes of around 23).

PS, US This album is the result of over 3 years worth of collaboration, coming together to form a beautiful marriage of sweet female vocals, alongside pristine, lusciously textured and layered electronics, and some clever yet funky beat programming.

 Comet C/1995 O1 (Hale-Bopp)
It is most unusual for a comet to be discovered at such a great distance from the Sun and immediately astronomers were excited that Hale-Bopp might become the brightest comet in living memory.
The nucleus of a comet, often described as a dirty snowball, is typically a few kilometres in size and is thought to arise from the debris remaining after the formatiom of the Solar System.
Comet Hale-Bopp's orbit is inclined at almost 90 degrees to this plane.

 Comet Hale-Bopp's Light Curve   (Site not responding. Last check: 2007-11-06)
The observations show that the comet's behaviour has been very steady indeed since October, obeying a brightening law similar to the average for dynamically fairly new comets (ie: ones, like Hale-Bopp, which have orbited the Sun a few times, but still have periods of thousands of years).
For some comets the drop in the rate of brightening at this distance can be very large: even for Comet Halley it was more than a factor of 2 and for Comet Austin it was about a factor of 4, explaining why the comet was eventually so disappointing.
Comet Hyakutake did something similar, but at a rather closer distance to the Sun, hence it was spectaucular when it passed by the Earth, but a disappointing object near perihelion.

The comet, also known as C/1996 B2, was discovered by Japanese comet-hunter Yuji Hyakutake, who spotted the celestial object with powerful binoculars on Jan. 30.
Comets on their first trip through our neighborhood are usually less spectacular than ones that have been by before, says Magee-Sauer.
Although predicting the brightness of an approaching comet is notoriously tricky, Magee-Sauer says measurements thus far indicate that Comet Hyakutake has a good chance of becoming a notably bright object, even to the naked eye.

 PS Comet - Everything on PS Comet (information, latest news, articles,...)
In 1812 the Comet made a delivery voyage from Port Glasgow (a town just to the east of Greenock) 21 miles upriver to the Broomielaw, Glasgow, then sailed from Glasgow the 24 miles down to Greenock, making five miles an hour against a head-wind.
Then he had the Comet lengthened and re-engined and from September 1819 ran a service to Oban and Fort William (via the Crinan Canal) a trip which took four days, but in 1820 the Comet was shipwrecked in strong currents at Craignish Point near Oban.
Although Bell built a second Comet this was not a success.

A small portion of the samples will be used to make a preliminary study of the returned material, with the rest to be made available to scientists around the world for research.
Now that the team has the samples, they are going to have to search the grids for the comet and interstellar dust particles before they can analyze them.

 C/LINEAR : May 2001
The rest of the nucleus broke up into larger fragments, which resemble mini-comets and are seen clustered near the western tip of the tail (celestial east is the left and north is to the top).
Comet C/LINEAR, whose official name is C/1999 S4, was discovered on 27 September 1999 by the Lincoln Near Earth Asteroid Research (LINEAR) program when it was 4.3 astronomical units from the Sun (AU; 1 AU is the average Earth-Sun distance = 150 million km = 93 million miles).
At that time, the comet was unusually bright, given that it was still very far from the Sun (for comparison, Jupiter is about 5 AU from the Sun), which fueled expectations that C/LINEAR might become visible to the naked eye during the summer of 2000.

Now, if you're still convinced that what have found is really a comet, it would be helpful if you could check one of the several readily-available publications listing ephemerides of already-known comets.
At any given time, there are usually at least 2 or 3 (often more) comets visible in the night sky which are within the visual range of an 8-inch reflector.
Good sources for the positions of known comets include the International Astronomical Union (IAU) Circulars, the Minor Planet Circulars, the annual Comet Handbook of the International Comet Quarterly, and the annual Handbook of the British Astronomical Association.
