Asteroid 1999 KW4 Distance from Earth
The distance of Asteroid 1999 KW4 from Earth is currently 268,088,714 kilometers, equivalent to 1.792062 Astronomical Units. Light takes 14 minutes and 54.2477 seconds to travel from Asteroid 1999 KW4 and arrive to us.
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 January 2013 and 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
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.
Asteroid 1999 KW4 rise and set times
The rise and set times are defined as the time at which the upper limb of Asteroid 1999 KW4 touches the horizon, considering the effect of the atmospheric refraction. As the atmospheric conditions cannot be modeled precisely the times reported here should be considered correct with an approximation of few minutes.
