The Moon Distance from Earth
The distance of The Moon from Earth is currently 393,952 kilometers, equivalent to 0.002633 Astronomical Units. Light takes 1.3141 seconds to travel from The Moon and arrive to us.
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 January 2013 and December 2100, the closest approach of The Moon to Earth happens on Sun Nov 26 2034 at a distance of 0.002383 Astronomical Units, or 356,452 kilometers:
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 -9.02.
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.
The Moon rise and set times
Location: Greenwich, United Kingdom [change]
Latitude: 51° 28’ 47” N
Longitude: 0° 00’ 00” E
Timezone: Europe/London
Today's The Moon rise, transit and set times from Greenwich, United Kingdom [change] are the following (all times relative to the local timezone Europe/London):
The rise and set times are defined as the time at which the upper limb of The Moon 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.
