Asteroid 2012 TC4 Distance from Earth
The distance of Asteroid 2012 TC4 from Earth is currently 177,366,194 kilometers, equivalent to 1.185620 Astronomical Units. Light takes 9 minutes and 51.6299 seconds to travel from Asteroid 2012 TC4 and arrive to us.
The following chart shows the distance of Asteroid 2012 TC4 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 2012 TC4 from Earth is also available as a real time updated value in the Live Position and Data Tracker.
Closest Approach of Asteroid 2012 TC4 to Earth
Between 1 January 2013 and 30 December 2100, the closest approach of Asteroid 2012 TC4 to Earth happens on Thu Oct 12 2017 at a distance of 0.001009 Astronomical Units, or 150,973 kilometers:
NOTE: values for the closest approach are computed with a sampling interval of 1 day.
Asteroid 2012 TC4 Brightness and Light Curve
The following chart is the predicted light curve (visual magnitude as a function of time) of Asteroid 2012 TC4, 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.
