277 Elvira is a typical main belt asteroid and is a member of the Koronis asteroid family. It was discovered by Auguste Charlois on May 3, 1888 in Nice. (277) Elvira is possibly named for a character in Alphonse de Lamartine’s Méditations poétiques (1820) and Harmonies poétiques et religieuses (1830).<ref>Schmadel Lutz D.

A group of astronomers, including Lucy D’Escoffier Crespo da Silva and Richard P. Binzel, used observations made between 1998 through 2000 to determine the spin-vector alignment of the Koronis family of asteroids, including 277 Elvira. The collaborative work resulted in the creation of 61 new individual rotation lightcurves to augment previous published observations.<ref>Slivan, S. M., Binzel, R. P., Crespo da Silva, L. D., Kaasalainen, M., Lyndaker, M. M., Krco, M.: “Spin vectors in the Koronis family: comprehensive results from two independent analyses of 213 rotation lightcurves,”Icarus, 162, 2003, pp. 285-307.</ref>

Measurements of the thermal inertia of 277 Elvira give a value of around 190 m−2 K−1 s−1/2, compared to 50 for lunar regolith and 400 for coarse sand in an atmosphere.<ref name="Delbo2009"/>
