4 6 Demonstration service of EPN-TAP v1: main characteristics of planets. Data are included in the table, therefore most relevant parameters are non-standard in EPN-TAP. Data are retrieved from Archinal et al 2009 (IAU report, 2011CeMDA.109..101A) [radii] and Cox et al 2000 (Allen's astrophysical quantities, 2000asqu.book.....C) [masses, heliocentric distances, and rotation periods]. </meta>
