Comet Skjellerup–Maristany, formally designated C/1927 X1, 1927 IX, and 1927k, was a long-period comet which became very bright in 1927. This great comet was observable to the naked eye for about 32 days.[2] It was independently discovered by amateur astronomers John Francis Skjellerup in Australia on November 28, 1927 and Edmundo Maristany in Argentina on December 6, 1927, and noted for its strong yellow appearance, caused by emission from sodium atoms.

Forward scattering of light on December 15 and 16 of 1927 allowed the comet to be seen during daylight if the observer blocked the Sun.[3] C/1927 X1 passed only 1.4° from the Sun on 1927-Dec-15.[4]
It has been more than 105 AU (15.7 billion km) from the Sun since 2010.
The comet was mentioned in J. R. R. Tolkien's book Letters From Father Christmas.

C/1927 X1 (Skjellerup-Maristany) ist ein Komet, der in den Jahren 1927 und 1928 auch am Tage mit dem bloßen Auge gesehen werden konnte. Er wird aufgrund seiner außerordentlichen Helligkeit zu den „Großen Kometen“ gezählt.- [en] Comet Skjellerup–Maristany

El cometa Skjellerup-Maristany, nombre oficial C/1927 X1, 1927 IX, y 1927k, fue un cometa que se volvió muy brillante en el año 1927. Fue descubierto por separado por dos astrónomos aficionados: John Francis Skjellerup en Australia el 28 de noviembre de 1927 y Edmundo Maristany en Argentina el 6 de diciembre de 1927, y fue notorio por su fuerte aspecto amarillo, causado por la emisión de átomos de sodio. Fue considerado un Gran cometa.Другой контент может иметь иную лицензию.
