Distance of Asteroid 2 Pallas from Earth

The following chart shows the distance of Asteroid 2 Pallas 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 2 Pallas is also available as a real time updated value in the Live Position and Data Tracker.

Light Curve of Asteroid 2 Pallas

The following chart is the predicted light curve (visual magnitude as a function of time) of Asteroid 2 Pallas, 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.
