Editing 16 Psyche (section)

=== Size ===
The first size estimate of Psyche was {{convert|253|km||abbr=}} and came from [[IRAS]] thermal [[infrared]] emission observations.<ref name=JPL/> This is 15% larger than the currently accepted mean value, but was later found to be an accurate estimate for the IRAS viewing aspect because Psyche was viewed pole-on at the time of the measurement.<ref name=Shepard-Richardson-etal-2017/><ref name=Lupishko-1999/>

Psyche has been observed to [[Occultation#Asteroids|occult]] a star on nine occasions.<ref name="Shepard-Richardson-etal-2017" /> Four of these, 2004,<ref name="Shepard-Richardson-etal-2017" /> 2010,<ref name="PSI-asteroid-data-sets" /><ref name="Psyche_occultation_2010" /> 2014,<ref name="PSI-asteroid-data-sets" /> and 2019,<ref name="Psyche_occultation_2019" /> generated [[Chord (astronomy)|multi-chord]] data sets<ref name=PSI-asteroid-data-sets/> and have been used along with adaptive optics imaging and three-dimensional modeling to estimate Psyche's mean diameter, with recent models all converging to an equivalent-volume mean diameter of {{val|222|3}}&nbsp;km.<ref name="Hanuš-Viikinksk-etal-2017"/><ref name=DAMIT-1806-cuni-cz/><ref name="Viikinksk-Vernza-etal-2018" /><ref name="Ferrais-Vernazza-etal-2020" /><ref name="Shepard2021" />
