Dwarf Planet Pluto Distance from Earth
The distance of Dwarf Planet Pluto from Earth is currently 5,262,386,055 kilometers, equivalent to 35.176878 Astronomical Units. Light takes 4 hours, 52 minutes and 33.4304 seconds to travel from Dwarf Planet Pluto and arrive to us.
The following chart shows the distance of Dwarf Planet Pluto 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 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 14.41.
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):
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.
