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.
As the science of astronomy developed planetary theories, understanding the nature and composition of comets became a challenging mystery and a large area of study. Halley's comet, reappearing every 75–76 years, was pivotal to the study of comets, especially of their orbits.
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 ...
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 ...
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.
Due to the massive size of its nucleus, Comet Hale–Bopp was observed intensively by astronomers during its perihelion passage, and several important advances in cometary science resulted from these observations. The dust production rate of the comet was very high (up to 2.0 × 10 6 kg/s), [43] which may have made the inner coma optically ...

Halley's Comet is the only known short-period comet that is consistently visible to the naked eye from Earth, [16] appearing every 72–80 years, [17] though with the majority of recorded apparations (25 of 30) occurring after 75–77 years.
