The comet passed about 0.335 AU (50.1 million km; 31.1 million mi) from the Earth on 5 May 1861 and last came to perihelion (closest approach to the Sun) on 3 June 1861. [3] C/1861 G1 is listed as a long-period "non-periodic comet" because it has not yet been observed at two perihelion passages.
The source of the meteor shower are particles of dust shed by the long-period Comet C/1861 G1 Thatcher. [1] The April Lyrids are the strongest annual shower of meteors from debris of a long-period comet, mainly because as far as other intermediate long-period comets go (200–10,000 years), this one has a relatively short orbital period of ...
The Lyrids are space dust from the comet Thatcher (C/1861 G1), which orbits the sun every 415 years. The comet was discovered in 1861, but the shower has been observed for more than 2,600 years.
The Great Comet of 1861, formally designated C/1861 J1 and 1861 II, is a long-period comet that was visible to the naked eye for approximately 3 months. [6] It was categorized as a great comet —one of the eight greatest comets of the 19th century.
In comet nomenclature, the letter before the "/" is either "C" (a non-periodic comet), "P" (a periodic comet), "D" (a comet that has been lost or has disintegrated), "X" (a comet for which no reliable orbit could be calculated —usually historical comets), "I" for an interstellar object, or "A" for an object that was either mistakenly ...
Discovered last year, the comet C/2023 A3 Tsuchinshan-ATLAS will be visible in the California sky on Saturday night for the first time in 80,000 years.
A bright comet could be visible in skies across the globe over the coming days for the first time in 160,000 years. Nasa said the future brightness of a comet is "notoriously hard" to predict, but ...
A rare comet is still glowing over Ohio. Here's how to see it before it's gone, and won't return for 80,000 years.
