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.

Distance from Earth
The distance of Asteroid 11 Parthenope from Earth is currently
The following chart shows the distance of Asteroid 11 Parthenope from Earth as a function of time. In the chart the distance data is measured in Astronomical Units and sampled with an interval of 1 day.
The value of the reported distance might be somewhat inaccurate around the times of closest approach for objects passing extremely close to Earth. The value of the distance of 11 Parthenope from Earth is also available as a real time updated value in the Live Position and Data Tracker.
Closest Approach
Between 1 January 1900 and 31 December 2099, the closest approach of Asteroid 11 Parthenope to Earth happens on Mon Aug 11 2081 at a distance of 1.187050 Astronomical Units, or 177,580,172 kilometers:
NOTE: values for the closest approach are computed with a sampling interval of 1 day.
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.
