Asteroid 11 Parthenope
Asteroid 11 Parthenope is a large, main-belt asteroid with a diameter of approximately 162 kilometers. It was discovered on May 11, 1850, by Italian astronomer Annibale de Gasparis and named after the Siren of Greek mythology, Parthenope. The asteroid orbits the Sun between Mars and Jupiter, with a semi-major axis of approximately 2.45 astronomical units (AU) and an orbital period of about 4.04 years. Parthenope's orbit is relatively eccentric and inclined compared to other asteroids in the main belt. It rotates slowly, with a rotation period of about 16 hours. Parthenope is also classified as a C-type asteroid, indicating that its surface is likely rich in carbonaceous materials.
Asteroid 11 Parthenope is currently in the constellation of Ophiucus.
The current Right Ascension of Asteroid 11 Parthenope is 17h 02m 28s and the Declination is -16° 21’ 34” (topocentric coordinates computed for the selected location: Greenwich, United Kingdom ). The current magnitude of Asteroid 11 Parthenope is 9.54 (JPL).

Asteroid 11 Parthenope Brightness and Light Curve
The following chart is the predicted light curve (visual magnitude as a function of time) of Asteroid 11 Parthenope, 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.
