126P/IRAS is a Jupiter-family comet with an orbital period of 13.4 years. It was discovered in images taken by the Infrared Astronomical Satellite (IRAS) on 28 July 1983 by J. Davies. The discovery was confirmed with images taken with the 1.2-m Schmidt telescope at Palomar Observatory.
== Observational history == Upon discovery the comet had an apparent magnitude of 15 and appeared stellar in appearance. The comet brightened and in mid September 1983 reached an apparent magnitude of 11 while a tail 3.5 arcminutes long was observed. Brian G. Marsden computed its orbit and found it is a short period comet with an orbital period of 13.32 years. The comet was observed again during its next apparition in 1996, when it brightened up to magnitude of about 11 in September 1996 and faded to about 12 in October. The comet was observed during its 2010 and 2023 apparitions.
