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 2 Pallas from Earth is also available as a real time updated value in the Live Position and Data Tracker.

Closest Approach

Between 1 January 1600 and 30 December 2499, the closest approach of Asteroid 2 Pallas to Earth happens on Sat Feb 16 1608 at a distance of 1.193832 Astronomical Units, or 178,594,670 kilometers:

Light Curve

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.
