Apprehending the approach of Judgment Day, crowds besieged the shop of Mr. Petty, our preaching tailor, invoking his prayers. ” On June 3, 1858, Italian astronomer Giovanni Battista Donati (1826–1873) discovered a comet in the constellation Leo. He called the comet faint and described its faint glow as 3 arcminutes across. Observations continued over the coming days and there was no indication, from the many notations of “very faint,” that this object would become a spectacle. 5 million km on October 10 and remaining visible for months.

The Great Comet of 1843 was so brilliant that numerous observers saw it in the daytime. At the end of February Italian observers described a “very beautiful star” with a tail stretching 5° long. Although Europe was in a cloudy period, North American sky watchers gobbled up the comet. Reports suggested that on February 28, a “large part of the adult population” of Waterbury, Connecticut, observed the comet. As March 1843 began, the Great Comet’s tail moved into the evening sky. On March 3 a number of observers reported seeing a double tail.

By December the tail had shrunk to 7° and after the New Year few observations were made. ” Tycho then wrote extensively about the Great Comet of 1577 and drew some scientific conclusions from his observations. He claimed the raylike structure of the comet’s tail represented the Sun’s rays shining through the comet. He tried to calculate the parallax and determined the comet was at least 230 times the radius of Earth away from our planet. He also realized that his size measurements of the comet – combined with the distance he had calculated – meant the comet was much larger than anything anyone had previously imagined.
