The following chart shows the distance of Asteroid 5 Astraea 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 5 Astraea from Earth is also available as a real time updated value in the Live Position and Data Tracker.
Closest Approach of Asteroid 5 Astraea to Earth
Between 1 January 1900 and 31 December 2099, the closest approach of Asteroid 5 Astraea to Earth happens on Fri Feb 13 1925 at a distance of 1.093100 Astronomical Units, or 163,525,365 kilometers:
NOTE: values for the closest approach are computed with a sampling interval of 1 day.
Asteroid 5 Astraea Brightness
The current visual magnitude of Asteroid 5 Astraea is 12.43.
The following chart is the predicted light curve (visual magnitude as a function of time) of Asteroid 5 Astraea, 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.
