196 Philomela is a large and bright main-belt asteroid. It is an S-type asteroid.[citation needed]
It was discovered by C. H. F. Peters on May 14, 1879, in Clinton, New York and named after Philomela, the woman who became a nightingale in Greek mythology.[3]
In the late 1990s, a network of astronomers worldwide gathered light curve data that was ultimately used to derive the spin states and shape models of 10 new asteroids, including (196) Philomela. The shape model for this asteroid is described as asymmetrical and smooth, while the light curve varies by up to 0.4 in magnitude.[2][4]
To date there have been two reported Philomelian stellar occultations.[citation needed]
