However, due to the faintness of the stars, only a few of the planets were also detected with radial velocity follow-ups, and therefore the planetary masses were mostly unknown. It therefore yet to be determined whether planetary systems indeed behave as &quot;peas in a pod&quot;.&nbsp;<br> &nbsp;Follow-up programs of TESS targets significantly increased the number of confirmed planets with mass measurements, allowing for a more detailed statistical analysis of multi-planet systems. In this work we explore the similarity in radii, masses, densities, and period ratios of planets within planetary systems.&nbsp;<br> &nbsp;We &nbsp;show that planets in the same system that are similar in radii could be rather different in mass and vice versa. Nevertheless, planets are somewhat &nbsp;similar in mass up to masses of ~100Me and radii of ~10Re. We find that in general, the planetary radii of a given planetary system are more similar than the masses. &nbsp;We conclude that other quantities like the density may be crucial to fully understand the nature of planetary systems and that, due to the diversity of planets within a planetary system, increasing the number of detected systems is crucial for understanding the exoplanetary demographics.&nbsp;</p></dct:description> <dct:accessRights rdf:resource="http://publications.europa.eu/resource/authority/access-right/PUBLIC"/> <dct:accessRights> <dct:RightsStatement rdf:about="info:eu-repo/semantics/openAccess"> <rdfs:label>Open Access</rdfs:label> </dct:RightsStatement> </dct:accessRights> <dcat:distribution> <dcat:Distribution> <dct:license rdf:resource="https://creativecommons.org/licenses/by/4.0/legalcode"/> <dcat:accessURL rdf:resource="https://doi.org/10.5281/zenodo.5561371"/> </dcat:Distribution> </dcat:distribution> <dcat:distribution> <dcat:Distribution> <dcat:accessURL rdf:resource="https://doi.org/10.5281/zenodo.5561371"/> <dcat:byteSize>723313</dcat:byteSize> <dcat:downloadURL rdf:resource="https://zenodo.org/record/5561371/files/poster.pdf"/> <dcat:mediaType>application/pdf</dcat:mediaType> </dcat:Distribution> </dcat:distribution> </rdf:Description> </rdf:RDF>
