The year 1858 in science and technology involved some significant events, listed below.
Alphonse Louis Nicolas Borrelly was a French astronomer born in Roquemaure, Gard.
Antonio Pacinotti was an Italian physicist, who was Professor of Physics at the University of Pisa.
Giovanni Battista Donati was an Italian astronomer.
Comet Donati, or Donati's Comet, formally designated C/1858 L1 and 1858 VI, is a long-period comet named after the Italian astronomer Giovanni Battista Donati who first observed it on June 2, 1858. After the Great Comet of 1811, it was the most brilliant comet that appeared in the 19th century. It was also the first comet to be photographed.
Giovanni Battista was a common Italian given name in the 16th-18th centuries. It refers to "John the Baptist" in English, the French equivalent is "Jean-Baptiste". Common nicknames include Giambattista, Gianbattista, Giovambattista, or Giambo. In Genoese the nickname was Baciccio, and a common shortening was Giovan Battista, Giobatta or simply G.B.. The people listed below are Italian unless noted otherwise.
Comet Pons may refer to any one of these comets:
D/1770 L1, popularly known as Lexell's Comet after its orbit computer Anders Johan Lexell, was a comet discovered by astronomer Charles Messier in June 1770. It is notable for having passed closer to Earth than any other comet in recorded history, approaching to a distance of only 0.015 astronomical units, or six times the distance from the Earth to the Moon. The comet has not been seen since 1770 and is considered a lost comet.
Martin Hoek was a Dutch astronomer and experimental physicist.
The Great Southern Comet of 1865, also known as C/1865 B1 by its modern nomenclature, was a non-periodic comet, which in 1865 was so bright that it was visible to unaided-eye observations in the Southern Hemisphere. The comet could not be seen from the Northern Hemisphere.
Donati is an Italian surname. Notable people with the surname include:
2018 VG18 is a distant trans-Neptunian object (TNO) that was discovered when it was 123 AU (18 billion km; 11 billion mi) from the Sun, more than three times the average distance between the Sun and Pluto. It was discovered on 10 November 2018 by Scott Sheppard, David Tholen, and Chad Trujillo during their search for TNOs whose orbits might be gravitationally influenced by the hypothetical Planet Nine. They announced the discovery of 2018 VG18 on 17 December 2018 and nicknamed the object "Farout" to emphasize its distance from the Sun.
2018 AG37 is a distant trans-Neptunian object and centaur that was discovered 132.2 ± 1.5 AU (19.78 ± 0.22 billion km) from the Sun, farther than any other currently observable known object in the Solar System. Imaged in January 2018 during a search for the hypothetical Planet Nine, the confirmation of this object was announced in a press release in February 2021 by astronomers Scott Sheppard, David Tholen, and Chad Trujillo. The object was nicknamed "FarFarOut" to emphasize its distance from the Sun.
Comet Donati, formally designated as C/1855 L1, is a long-period comet that has an orbital period of approximately 252 years. It was the second comet discovered in 1855, and the first of five comets discovered by Italian astronomer, Giovanni Battista Donati.
Comet Donati–van Arsdale, formally designated as C/1857 V1, is a parabolic comet co-discovered by Giovanni Battista Donati and Robert van Arsdale a few hours apart on 10 November 1857. It was calculated to have a retrograde trajectory around the Sun.
Comet Donati–Toussaint, formally designated as C/1864 O1, is a non-periodic comet co-discovered by Italian astronomers, Giovanni Battista Donati and Carlo Toussaint in July 1864.
Comet Donati, formally designated as C/1864 R1, is a parabolic comet discovered in 1864. It was the last of five comets discovered by Italian astronomer, Giovanni Battista Donati.
