The Moon Distance from Earth

The distance of The Moon from Earth is currently 363,686 kilometers, equivalent to 0.002431 Astronomical Units. Light takes 1.2131 seconds to travel from The Moon and arrive to us.

1.2131 seconds

The following chart shows the distance of The Moon 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.

Closest Approach of The Moon to Earth

Between 1 January 1600 and 30 December 2499, the closest approach of The Moon to Earth happens on Wed Jan 13 2275 at a distance of 0.002382 Astronomical Units, or 356,377 kilometers:

Wed Jan 13 2275

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

The Moon Brightness

The current visual magnitude of The Moon is -5.43.


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