The word comet derives from the Old English cometa from the Latin comēta or comētēs. That, in turn, is a romanization of the Greek κομήτης 'wearing long hair', and the Oxford English Dictionary notes that the term (ἀστὴρ) κομήτης already meant 'long-haired star, comet' in Greek.

Comet Tucker, formally designated as C/2004 Q1, is a faint non-periodic comet that had a very distant perihelion on 11 December 2004. It was the second of two comets discovered by famed amateur astronomer, Roy A. Tucker .
The comet was first spotted as a magnitude 16.4 object by the ASAS-SN survey from images taken at the Cerro Tololo Observatory's 14-cm "Cassius" telescope between 7–11 July 2018. [ 3 ] [ 4 ] It made its closest approach to Earth on 19 October 2019 at a distance of 205 million mi (330 million km) before reaching perihelion on 11 November 2019.
Circumbinary planet – an exoplanet that orbits two stars. Hot Jupiter – an exoplanet whose characteristics are similar to Jupiter, but that have high surface temperatures because they orbit very close to their parent stars, whereas Jupiter orbits its parent star (the Sun ) at 5.2 AU (780×106 km), causing low surface temperatures.
In an attempt to link the 1843 and 1880 comets to the comet in 1106 and 371 BC, Kreutz measured the fragments of the 1882 comet and determined that it was likely a fragment of the 1106 comet. He then designated that all sungrazing comets with similar orbital characteristics as these few comets would be part of the Kreutz Group .

Soon after the first orbital elements could be calculated, it was suggested that the comet would become "a bright object, that could be observed with unaided eye."It was found to combine three favorable characteristics that made it an exceptional comet for observation: a short perihelion distance, a short distance from Earth, and high intrinsic brightness.
