Editing 624 Hektor (section)

== Studies ==
624 Hektor was in a 2003 study of asteroids using the Hubble [[Fine Guidance Sensor (HST)|FGS]].<ref name="Tanga-2003" /> Asteroids studied include [[63 Ausonia]],  [[15 Eunomia]], [[43 Ariadne]], [[44 Nysa]], and 624 Hektor.<ref name="Tanga-2003" /> It has since been revisited several times, particularly as a test of the upgraded resolution of the Keck Observatory's LGS Adaptive Optics system which allowed Earth-based observation of binary asteroids for the first time.<ref name="Marchis-LGS" /><ref name="Marchis-2014" /> The asteroid has also been imaged by the [[NEOWISE]] and [[AKARI]] all-sky studies, which reported highly divergent size estimates of 147.4<ref name="Grav-2012" /> and 231.0&nbsp;kilometers,<ref name="AKARI" /> respectively. This mostly arises from large differences in estimated [[albedo]] (approximately 0.107 for NEOWISE, and a much lower 0.034 for AKARI) rather than its [[absolute magnitude]] being measured only briefly at opposing extremes of a widely varying cycle such as thought to account for the uncertainty over the size of [[1173 Anchises]] (624 Hektor's own abs. mag. recorded as a relatively similar 7.20 and 7.49 by the two studies). It is, unusually, not included in the published [[IRAS]] results, and is therefore the largest Jupiter trojan to be omitted from that study.
