130 Elektra facts for kids
|
130 Elektra is a very big farther main belt asteroid. It was found by C. H. F. Peters on February 17, 1873 and named after Electra, an avenger in Greek mythology. Its spectrum is of the G type, so it is probably made up like Ceres. Spectral signatures of organic compounds have been seen on Elektra's surface Recent optical sightings have found a moon (see below). Using its orbit, Elektra's mass can be found more correctly. The value of 1.3×1019 kg indicates an unusually high density (for asteroids) of 3.8 ± 0.3 g/cm³. Optical sightings have also determined that Elektra's shape is quite non-spherical, as well as giving indications of albedo differences of 5-15% on its surface. Moon (S/2003 (130) 1)
