Distance of Asteroid 11 Parthenope from Earth

The following chart shows the distance of Asteroid 11 Parthenope from Earth as a function of time. Distance data is measured in Astronomical Units and sampled with a 2 days interval.

The reported distances might be inaccurate around the times of closest approach for objects passing extremely close to Earth. The value of the distance of 11 Parthenope is also available as a real time updated value in the Live Position and Data Tracker.

Light Curve of Asteroid 11 Parthenope

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.
