Comet Shajn–Comas Solá, formal designation C/1925 F1, is a hyperbolic comet co-discovered by Grigory Shajn and Jose Comas Solá. At the time, it was the comet with the most distant known perihelion, which enabled astronomers to continue observing it until 1927.
Little is known of what people thought about comets before Aristotle, who observed his eponymous comet, and most of what is known comes secondhand.From cuneiform astronomical tablets, and works by Aristotle, Diodorus Siculus, Seneca, and one attributed to Plutarch but now thought to be Aetius, it is observed that ancient philosophers divided themselves into two main camps.
Scientists believe Comet 12P/Pons-Brooks boasts an enormous diameter of about 10.5 miles, and the last time it passed this close to Earth was in 1954. Extremely rare 'devil comet' expected to pass ...
Periodic comets usually have elongated elliptical orbits, and usually return to the vicinity of the Sun after a number of decades. The official names of non-periodic comets begin with a "C"; the names of periodic comets begin with "P" or a number followed by "P". Comets that have been lost or disappeared have names with a "D". Comets whose ...
Comets whose aphelia are near a major planet's orbit are called its "family". [81] Such families are thought to arise from the planet capturing formerly long-period comets into shorter orbits. [82] At the shorter orbital period extreme, Encke's Comet has an orbit that does not reach the orbit of Jupiter, and is known as an Encke-type comet.
The 96P sungrazer family is a small group of sungrazing comets, originating from the comet 96P/Machholz. It is only observed by LASCO corongraphs aboard SOHO (Solar and Heliospheric Observatory) probe. It contains three subgroups: Marsden, Kracht and Kracht II.
Comet Kohoutek (formally designated C/1973 E1 and formerly as 1973 XII and 1973f) [c] is a comet that passed close to the Sun towards the end of 1973. Early predictions of the comet's peak brightness suggested that it had the potential to become one of the brightest comets of the 20th century, capturing the attention of the wider public and the press and earning the comet the moniker of "Comet ...
New research finds that the dark silicate glass strewn across a vast swath of the Atacama Desert was created by an exploding comet around 12,000 years ago. (Image/P.H. Schultz, Brown University)
