'''32P/Comas Solà''' is a [[List of numbered comets|periodic comet]] with a current orbital period of 9.7 years around the [[Sun]].

== Observational history ==
''32P/Comas Solà'' was discovered November 5, 1926, by [[Josep Comas Solà]]. As part of his work on [[asteroid]]s for the [[Fabra Observatory]] ([[Barcelona]]), he was taking photographs with a {{convert|6|in|mm|adj=on}} telescope. The comet's past orbital evolution became a point of interest as several astronomers suggested early on that the comet might be a return of the then lost periodic comet ''Spitaler'' ([[113P/Spitaler]]). In 1935 additional positions had been obtained, and P. Ramensky investigated the orbital motion back to 1911. He noted the comet passed very close to [[Jupiter]] during May 1912 and that, prior to this approach, the comet had a [[perihelion]] distance of 2.15 [[astronomical unit|AU]] and an orbital period of 9.43 years. The identity with comet ''Spitaler'' was thus disproven.

In 1933, the Danish astronomer [[Julie Vinter Hansen]] undertook significant new research which calculated the orbit of the comet up to 1980, predicting when it would return to the Earth's orbit.<ref>{{Cite journal|title=The periodic comet Comas Sola (1926 f) at its return in the year 1935|last=Hansen|first=Julie M.

In 1969, Soviet astronomers [[Klim Churyumov]] and [[Svetlana Gerasimenko]] searched for 32P/Comas Solà on photographic plates, and [[serendipity|serendipous]]ly discovered a new comet, [[67P/Churyumov-Gerasimenko]].<ref name="Kronk">{{cite book |chapter-url=https://books.google.com/books?id=qV4Q49x8PTsC&pg=PA241 |chapter=67P/1969 R1 (Churyumov-Gerasimenko) |title=Cometography: A Catalog of Comets; Volume 5: 1960–1982 |publisher=Cambridge University Press |first1=Gary W. |last1=Kronk |first2=Maik |last2=Meyer |name-list-style=amp |pages=241–245 |year=2010 |isbn=978-0-521-87226-3}}</ref>
