Asteroid 87 Sylvia was discovered on May 16, 1866, by English astronomer Norman Robert Pogson. It is a relatively large main-belt asteroid, with a diameter of approximately 286 kilometers. The asteroid is named after Rhea Sylvia, the mythical mother of the founders of Rome, Romulus and Remus. Sylvia has an orbital period of 5.5 years and an average distance from the Sun of approximately 3 astronomical units. It is a member of the Cybele group, which is a large group of asteroids that share similar orbital characteristics.
Sylvia is notable for having a satellite system discovered in 2001 by Franck Marchis and his team and composed by two orbiting satellites named (87) Sylvia I Romulus and (87) Sylvia II Remus.

Light Curve
The following chart is the predicted light curve
(visual magnitude as a function of time) of Asteroid 87 Sylvia,
according to the most recent ephemerides data.
Magnitude data is sampled with a 2 days interval and there might be inaccuracies
for objects changing brightness very rapidly during the course of a few days. For comets there could be large discrepancies
between the observed and predicted brightness because of their highly dynamic behaviour.
