Asteroid 2018 AJ Distance from Earth
The distance of Asteroid 2018 AJ from Earth is currently 93,701,266 kilometers, equivalent to 0.626354 Astronomical Units. Light takes 5 minutes and 12.5538 seconds to travel from Asteroid 2018 AJ and arrive to us.
The following chart shows the distance of Asteroid 2018 AJ 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 2018 AJ from Earth is also available as a real time updated value in the Live Position and Data Tracker.
Closest Approach of Asteroid 2018 AJ to Earth
Between 1 January 2013 and 30 December 2100, the closest approach of Asteroid 2018 AJ to Earth happens on Wed Jan 24 2018 at a distance of 0.012035 Astronomical Units, or 1,800,431 kilometers:
NOTE: values for the closest approach are computed with a sampling interval of 1 day.
Asteroid 2018 AJ Brightness and Light Curve
The following chart is the predicted light curve (visual magnitude as a function of time) of Asteroid 2018 AJ, 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.
