The distance of Asteroid 87 Sylvia from Earth is currently
The following chart shows the distance of Asteroid 87 Sylvia 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 87 Sylvia from Earth is also available as a real time updated value in the Live Position and Data Tracker.
Closest Approach
Between 1 January 1900 and 31 December 2099, the closest approach of Asteroid 87 Sylvia to Earth happens on Mon Aug 22 2095 at a distance of 2.153632 Astronomical Units, or 322,178,836 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 87 Sylvia, 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.
