The Sun
The Sun is currently in the constellation of Leo. The current Right Ascension of The Sun is 09h 40m 16s and the Declination is +13° 56’ 16” (topocentric coordinates computed for the selected location: Greenwich, United Kingdom [change]). The current magnitude of The Sun is -26.71 (JPL).
Summary of key facts about The Sun [tip: you can also create a Quick Access page for this data if you access it frequently and would like to have a simpler view]:
- Sun is above the horizon from Greenwich, United Kingdom [change].
- It is visible looking in the East-South-East direction at an altitude of 40° above the horizon.

The Sun Distance from Earth
The distance of The Sun from Earth is currently 151,507,482 kilometers, equivalent to 1.012765 Astronomical Units. Light takes 8 minutes and 25.3746 seconds to travel from The Sun and arrive to us.
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 January 1900 and January 2100 the closest approach of The Sun to Earth happens on Thu Jan 3 1901 at a distance of 0.98319152 Astronomical Units, or 147,083,358 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 -26.71.
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):
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.
