The Sun Distance from Earth

The distance of The Sun from Earth is currently 151,055,158 kilometers, equivalent to 1.009741 Astronomical Units. Light takes 8 minutes and 23.8658 seconds to travel from The Sun and arrive to us.

8 minutes and 23.8658 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.

Distance of The Sun from Earth between January 1900 and January 2100

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 January 1900 and January 2100, the closest approach of The Sun to Earth happens on Thu Jan 3 1901 at a distance of 0.983192 Astronomical Units, or 147,083,358 kilometers:

Thu Jan 3 1901

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 -26.72.


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.

The Sun 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 Sun rise, transit and set times from Greenwich, United Kingdom [change] are the following (all times relative to the local timezone Europe/London):

Azimuth: 72.7°
Max altitude: 55.9°
Azimuth: 287.5°

The rise and set times are defined as the time at which the upper limb of The Sun 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.
