Johann Baptist Cysat, Swiss Jesuit geometer and astronomer and one of Christoph Scheiner's pupils, becomes the first to study a comet through the telescope and gives the first description of the nucleus and coma of a comet. September 6–25 – The Great Comet of 1618 is visible to the naked eye. James I described it as "Venus with a firebrand ...
Reconstruction of the comet's trajectory indicates that C/1831 A1 must have been bright enough to be seen with the naked eye throughout the southern hemisphere (possibly even brighter than Venus) [6] prior to its perihelion on December 28, 1830. However, no written records of its appearance prior to its discovery have yet been found. [6]
As space objects go, comets and meteors are not very big. While a planet like Earth is about 8,000 miles in diameter and a star like our Sun is about 865,000 miles across, the largest asteroid ...

A comet is an icy, small Solar System body that warms and begins to release gases when passing close to the Sun, a process called outgassing.This produces an extended, gravitationally unbound atmosphere or coma surrounding the nucleus, and sometimes a tail of gas and dust gas blown out from the coma.
Comet C/2024 G3 has mesmerized astronomers and amateur skygazers for months as the world tried to spot the bright comet in the sky nearing its fatal encounter with the Sun. ... Science & Tech ...
