== Speculated influence of the planets ==
A 2012 paper proposed that the torque exerted by the planets on a non-spherical [[tachocline]] layer deep in the Sun may synchronize the solar dynamo.<ref name=Abreu>{{cite journal |last1=José Abreu|display-authors=etal |title=Is there a planetary influence on solar activity? |journal=Astronomy & Astrophysics |volume=548 |pages=A88 |date=2012 |doi=10.1051/0004-6361/201219997 |url=https://www.aanda.org/articles/aa/pdf/2012/12/aa19997-12.pdf|bibcode=2012A&A...548A..88A |doi-access=free }}</ref> Their results were shown to be an artifact of the incorrectly applied smoothing method leading to [[aliasing]].<ref name=Poluianov>{{cite journal |last1=S.

In 1974 the book ''[[The Jupiter Effect]]'' suggested that the alignment of the planets would alter the Sun's solar wind and, in turn, Earth's weather, culminating in multiple catastrophes on March 10, 1982. None of the catastrophes occurred. In 2023, a paper by Cionco et al. demonstrated the improbability that the suspected tidal effect on the Sun driven by Venus and Jupiter were significant on whole solar tidal generating potential.<ref>{{cite journal |last1=Cionco |first1=Rodolfo G. |last2=Kudryavtsev |first2=Sergey M. |last3=Soon |first3=Willie W.-H. |title=Tidal Forcing on the Sun and the 11-Year Solar-Activity Cycle |journal=Solar Physics |date=May 2023 |volume=298 |issue=5 |page=70 |doi=10.1007/s11207-023-02167-w|arxiv=2304.14168 |bibcode=2023SoPh..298...70C |s2cid=258352738 }}</ref>
