179 Klytaemnestra is a stony Telramund asteroid from the outer regions of the asteroid belt, approximately Template:Convert in diameter. It was discovered on 11 November 1877, by Canadian-American astronomer James Craig Watson at the old Ann Arbor Observatory in Michigan, United States.<ref name="MPC-object" /> It was his last discovery three years before his death.<ref name="Leuschner-1919" /> The transitional S-type asteroid has a rotation period of 11.17 hours.<ref name="lcdb" /> It was named after Clytemnestra from Greek mythology.<ref name="springer" />

Orbit and classification

Together with asteroid 9506 Telramund, Klytaemnestra is the largest members of the Telramund family (Template:Small),<ref name="Ferret" /> a mid-sized family of stony asteroids in the outer main belt, which is also known as the Klytaemnestra family.<ref name="Nesvorny-2014" />Template:Rp

It orbits the Sun in the outer main-belt at a distance of 2.6–3.3 AU once every 5 years and 1 month (1,871 days; semi-major axis of 2.97 AU). Its orbit has an eccentricity of 0.11 and an inclination of 8° with respect to the ecliptic.<ref name="jpldata" /> The body's observation arc begins at Lick Observatory in February 1899, more than 21 years after to its official discovery observation at Ann Arbor.<ref name="MPC-object" />

Physical characteristics

In the Tholen classification, Klytaemnestra is a common stony S-type asteroid,<ref name="jpldata" /> while in the SMASS classification it is a Sk-subtype, that transitions between the S- and K-type asteroids.<ref name="jpldata" />

Rotation period and poles

Photometric observations of this asteroid at the Oakley Observatory in Terre Haute, Indiana, during 2006 gave a light curve with a period of 11.13 ± 0.02 hours and a brightness variation of 0.55 ± 0.02 in magnitude (Template:Small).<ref name="Ditteon-2007" /> A better rated lightcurve, already obtained by Alan Harris in October 1979, gave a period of 11.173 hours with an amplitude of 0.35 (Template:Small).<ref name="Harris-1983a" />

A modeled lightcurve using photometric data from a larger international collaboration was published in 2016. It gave a period of 11.17342 hours, identical to the 1979-observations by Harris, as well as two spin axes at (65.0°, −6.0°) and (248.0°, −9.0°) in ecliptic coordinates (λ, β).<ref name="Hanus-2016a" />

Diameter and albedo

According to the surveys carried out by the Infrared Astronomical Satellite IRAS, the Japanese Akari satellite and the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, Klytaemnestra measures between 64.25 and 90.17 kilometers in diameter and its surface has an albedo between 0.119 and 0.245.<ref name="AKARI" /><ref name="Masiero-2014" /><ref name="WISE" /><ref name="SIMPS" /><ref name="Masiero-2012" />

The Collaborative Asteroid Lightcurve Link adopts the results obtained by IRAS, that is, an albedo of 0.1609 and a diameter of 77.69 kilometers based on an absolute magnitude of 8.15.<ref name="lcdb" />

Naming

This minor planet was named from Greek mythology after Clytemnestra, the daughter of Leda and the Spartan king Tyndareus. She was the wife of Agamemnon and the mother Orestes, Electra, Iphigenia and Chrysothemis. Clytemnestra and her lover Aegisthus murdered Agamemnon on his return from the Trojan War.<ref name="springer" /> The minor planets Template:MoMP, Template:MoMP, Template:MoMP, Template:MoMP, Template:MoMP and Template:MoMP were named after these mythological figures.
