Comet 4P/Faye (also known as Faye's Comet or Comet Faye) is a
periodic Jupiter-family comet discovered in November 1843 by
Hervé Faye at the
Royal Observatory in
Paris
Paris () is the capital and most populous city of France, with an estimated population of 2,165,423 residents in 2019 in an area of more than 105 km² (41 sq mi), making it the 30th most densely populated city in the world in 2020. S ...

perihelia
An apsis (; ) is the farthest or nearest point in the orbit of a planetary body about its primary body. For example, the apsides of the Earth are called the aphelion and perihelion.

There are two apsides in any ellip ...

The comet was first observed by Faye on November 23, but bad weather prevented its confirmation until the 25th.][ It was so faint that it had already passed perihelion about a month before its discovery, and only a close pass by the ]Earth

had made it bright enough for discovery. Otto Wilhelm von Struve reported that the comet was visible to the naked eye at the end of November.[ It remained visible for smaller telescopes until January 10, 1844, and was finally lost to larger telescopes on April 10, 1844.][
In 1844, Friedrich Wilhelm Argelander and Thomas James Henderson independently computed that the comet was a short-period comet; by May, its period had been calculated to be 7.43 years.][ ]Urbain Le Verrier

The comet was missed during its apparitions in 1903 and 1918 due to unfavorable observing circumstances.][ It reached a brightness of about 9th magnitude in 2006.][
