The Great Comet of 1811 (formally designated C/1811 F1) was a comet that was visible to the naked eye for around 260 days. In October 1811, at its brightest, it displayed an apparent magnitude of 0, with an easily visible coma. In December one length of the double tail extended for over 60 degrees. It was categorized as a Great Comet , the 54th in recorded history and one of eight in the 19th century.
In many ways the comet was quite similar to Comet Hale-Bopp. It became spectacular without passing particularly close to either the Earth or the Sun, but had an extremely large and active nucleus. It was discovered on March 25, 1811 by Honoré Flaugergues at 2.7 AU from the sun and confirmed by Jean-Louis Pons and Franz Xaver, Baron Von Zach in April.
The sightings continued until June when it was lost to solar glare , it was recovered in August as a 5th magnitude object. The comet brightened as it approached perihelion in September and its minimum distance from Earth at 1.1 AUThe astronomical unit AU is a unit of distance, approximately equal to the mean distance between Earth and Sun. The currently accepted value of the AU is 149,597,870,691+-30 metres (about 150 million kilometres or 93 million miles). Earth's orbit is not a. The comet nucleus was estimated at 30-40 kmTo help compare different orders of magnitude this page lists lengths between 10 and 100 km (104 to 105 m). See also lengths of other orders of magnitude.

There are several kinds of orbital periods for objects around the Sun: The sidereal period is the time that it takes the object to make one full orbit around the was calculated at 3,757 years (later adjusted to 3,065 years).

Note that not all eyes have the same anatomy as a human eye. An eye is an organ that detects light. Different kinds of light-sensitive organ are found in a varie for 9 months, a record it held until the appearance of Comet Hale-Bopp.
