Parameters of other known exoplanets in comparison with WASP-117b. Left: metallicity content derived for several exoplanets, adapted from Chachan et al. (2019). WASP-117b is mainly comparable in mass and metallicity to WASP-107b (Kreidberg et al. 2018), WASP-39b (Wakeford et al. 2018) and Solar System values (e.g. Wong et al. 2004; Helled & Guillot 2018; Chachan et al. 2019; Movshovitz et al. 2020) Right: all transiting planets with orbital periods shorter than 100 days and the Neptune-desert limits as proposed by Mazeh et al. (2016). WASP-39b and WASP-107b lie clearly inside the Neptune desert and are thus probably subject to erosion processes. WASP-117b lies outside the Neptune desert.
