Mass-radius diagram. Here we show planets from the TEPCat catalogue of ‘well-studied transiting planets’ (as of October 2022; Southworth 2011, https://www.astro.keele.ac.uk/jkt/tepcat/allplanets-noerr.html). Grey dots are measurements with uncertainties larger than 30%, while black and coloured dots have smaller uncertainties. Points are colour coded according to the insolation, F, for those objects where it can be calculated. TOI-640 b is shown as the large square.
