Editing 16 Psyche (section)

===Mass and bulk density===
Psyche is massive enough that its gravity observably [[gravitational perturbation|perturbs]] other asteroids' orbits, which can be used to calculate a [[mass]] estimate. Historical values for Psyche's mass have ranged from {{val|1.6|e=19|u=kg}} to {{val|6.7|e=19|u=kg}}.<ref name=Kuzmanoski_Kovacevic_2002/><ref name=Elkins-Tanton_2020/> However, most recent estimates have begun to converge on values near {{val|2.287|0.070|e=19|u=kg}}.<ref name=Elkins-Tanton_2020/><ref name=Siltala_Granvik/> Assuming the mean volume of {{val|5.75|0.19|e=6|u=km3}}, this equates to a bulk density of {{val|3.977|0.253|u=g/cm3}}, which is considerably higher than most [[Small Solar System body|small Solar System bodies]].<ref name=Vernazza2021/><ref name=Elkins-Tanton_2020/><ref name=Siltala_Granvik/>
