The comet reached minimum elongation on 13 March, on 25°. [4] It reached its peak brightness in April. Jacobson spotted the comet with naked eye on April 18. David H. Levy reported that the comet had an apparent magnitude of 4.7 with the naked eye on April 24. In the end of April the tail of the comet was reported to be up to 2–3 degrees long.
A thick accumulation of dust layers might be a good description of all of the short period comets, as dust layers with thicknesses on the order of meters are thought to have accumulated on the surfaces of short-period comet nuclei. The accumulation of dust layers over time would change the physical character of the short-period comet.
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 .
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.

The Extrasolar Planets Encyclopaedia [9] is an astronomy website, founded in Paris, France at the Meudon Observatory by Jean Schneider in February 1995, [10] [11] which maintains a database of all the currently known and candidate extrasolar planets, with individual "note" pages for each planet and a full list interactive catalog spreadsheet ...
For observers in the Northern Hemisphere, the comet could be seen on the northwestern horizon, below the Big Dipper. North of 45 degrees north, the comet was visible all night in mid-July 2020. On July 30, Comet NEOWISE entered the constellation of Coma Berenices, below the bright star Arcturus. NEOWISE was retroactively dubbed the Great Comet ...

Krüger 60 was proposed as the origin of interstellar comet 2I/Borisov (formerly named C/2019 Q4 (Borisov)) in a preprint submitted to arXiv by Dybczyński, Królikowska, and Wysoczańska. [13] These authors had from other work a list of stars and stellar systems that can potentially act as perturbers of the Oort cloud comets, and searched it ...
