The following chart shows the distance of Asteroid 1999 KW4 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 1999 WK4 from Earth is also available as a real time updated value in the Live Position and Data Tracker.

Closest Approach of Asteroid 1999 KW4 to Earth

Between 1 January 2013 and 30 December 2100, the closest approach of Asteroid 1999 KW4 to Earth happens on Mon May 26 2036 at a distance of 0.016364 Astronomical Units, or 2,447,983 kilometers:

NOTE: values for the closest approach are computed with a sampling interval of 1 day.

Asteroid 1999 KW4 Brightness and Light Curve

The following chart is the predicted light curve (visual magnitude as a function of time) of Asteroid 1999 KW4, 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.
