Distance from Earth
The distance of Asteroid 3 Juno from Earth is currently
The following chart shows the distance of Asteroid 3 Juno 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 3 Juno 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 3 Juno to Earth happens on Thu Nov 5 1874 at a distance of 1.028769 Astronomical Units, or 153,901,649 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 3 Juno, 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.
