1 Introduction. Trans-Neptunian objects (TNOs) are small Solar System bodies that orbit the Sun with a semi-major axis larger than that of Neptune (Jewitt et al. 2008).Due to the low spatial density of material in this orbital region and the significant distance from the Sun, their global physical-chemical composition has been largely unaffected since their formation.May 25, 2023 · Based on the results, Frame's team classified TOI-2498 b as a hot and bloated "super-Neptune."
