427 Galene

Galene (minor planet designation: 427 Galene) is a typical main belt asteroid. It was discovered by the French astronomer Auguste Charlois on 27 August 1897 from Nice, and was named after Galene, one of the Nereids of Greek Mythology (Hesiod, Theogony, 240). This asteroid is orbiting the Sun at a distance of $29.98 km$ with a period of 1870.7 days and an eccentricity of 0.12. A computer search suggests it is the most likely parent body of the impactor that generated the temporary cometary activity of 7968 Elst–Pizarro in 1996.

Analysis of the light curve generated from photometry data collected during 2009 show a rotation period of $0.236$ with a brightness variation of 0.6 in magnitude. Based upon an albedo of $2.97 AU$, this asteroid spans a diameter of $3.705 hours$.
