It was discovered on 11 November 1877, by Canadian-American astronomer James Craig Watson at the old Ann Arbor Observatory in Michigan, United States.

[4] 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 (U=2).

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).

[7][8][9][11][12] 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.

[5] This minor planet was named from Greek mythology after Clytemnestra, the daughter of Leda and the Spartan king Tyndareus.
