The Sun Distance from Earth

The distance of The Sun from Earth is currently 149,315,805 kilometers, equivalent to 0.998115 Astronomical Units. Light takes 8 minutes and 18.0639 seconds to travel from The Sun and arrive to us.

8 minutes and 18.0639 seconds

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

Closest Approach of The Sun to Earth

Between 1 January 1600 and 30 December 2499, the closest approach of The Sun to Earth happens on Tue Dec 27 1605 at a distance of 0.983059 Astronomical Units, or 147,063,549 kilometers:

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

The Sun Brightness

The current visual magnitude of The Sun is -26.75.


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