By definition, a hyperbolic orbit means that the comet will only travel through the Solar System once, with the Sun acting as a gravitational slingshot, sending the comet hurtling out of the Solar System entirely unless its eccentricity is otherwise changed. Comets orbiting in this way still originate from the Solar System, however.
Comet Delavan, formally designated as C/1913 Y1, is a hyperbolic comet discovered by astronomer Pablo T. Delavan on December 18, 1913, from the La Plata Observatory in Argentina. [ 2 ] The comet was last seen on September 19, 1915. [ 4 ]
In 1903, Manuel de Simas later revised it to a hyperbolic trajectory. [7] J. M. Poor found that the comet had accelerated during its inbound flight to the Sun in 1900, [8] with Brian G. Marsden and Ichiro Hasegawa later calculating this original trajectory had an orbital period of 66,000 years before it was ejected from the Solar System. [4]
By 1900 comets were categorized as "periodic", with elliptical orbits, or "non-periodic", one-time with parabolic or hyperbolic orbits. Astronomers believed that planets captured non-periodic comets into elliptical orbits; each planet had a "family" of comets that it captured, with Jupiter's the largest.
Comet Shajn–Comas Solá, formal designation C/1925 F1, is a hyperbolic comet co-discovered by Grigory Shajn and Josep Comas Solá in 1925. At the time, it was the comet with the most distant known perihelion distance (until the discovery of 29P/Schwassmann–Wachmann two years later), which enabled astronomers to continue observing it until March 1927.
This is a list of comets (bodies that travel in elliptical, parabolic, and sometimes hyperbolic orbits and display a tail behind them) listed by type. Comets are sorted into four categories: periodic comets (e.g. Halley's Comet), non-periodic comets (e.g. Comet Hale–Bopp), comets with no meaningful orbit (the Great Comet of 1106), and lost comets (), displayed as either P (periodic), C (non ...
Comet Brooks–Swift, also known as C/1883 D1 by its modern nomenclature, is a hyperbolic comet that was visible telescopically to Earth in the early months of 1883. It was discovered independently by two American astronomers, William Robert Brooks and Lewis A. Swift .
