The Moon Position
The Moon is currently in the constellation of Ophiucus. The current Right Ascension is 18h 11m 56s and the Declination is -22° 04’ 59”.

The Moon Distance
The distance of The Moon from Earth is currently 391,640 kilometers, equivalent to 0.002618 Astronomical Units. Light takes 1.3064 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 0.00238278 Astronomical Units, or 356,459 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 -12.45.
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, consideting the effect of the atmospheric refraction. As the atmoshpere conditions cannot be modeled precisely the times reported here should be considered correct with an approximation of few minutes.
