Correction to: Nature Geoscience https://doi.org/10.1038/s41561-019-0330-x, published online 19 March 2019.

In the version of this Article originally published, in Table 1, there was an error in the ‘Period (equatorial J2000)’ parameter value. The value ‘4.276057’ should have been ‘4.296057’. Also, in the third paragraph of the main text, in the fifth sentence, the value ‘4.276057’ should have been ‘4.296059’. These have now been corrected in all versions of the Article.
