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 Pluto from Earth is also available as a real time updated value in the Live Position and Data Tracker.

Closest approach of Dwarf Planet Pluto to Earth

Between January 1900 and January 2100, the closest approach of Dwarf Planet Pluto to Earth happens on Tue May 8 1990 at a distance of 28.686961 Astronomical Units, or 4,291,508,288 kilometers:

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

Dwarf Planet Pluto brightness

The current visual magnitude of Dwarf Planet Pluto is 14.44.


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

Dwarf Planet Pluto rise and set times

Location: Greenwich, United Kingdom [change]
Latitude: 51° 28’ 47” N
Longitude: 0° 00’ 00” E
Timezone: Europe/London

Today's Dwarf Planet Pluto rise, transit and set times from Greenwich, United Kingdom [change] are the following (all times relative to the local timezone Europe/London):

Azimuth: 112.9°
Max altitude: 15.6°
Azimuth: 247.1°

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