Pioneer 11 Distance from Earth
The distance of Pioneer 11 from Earth is currently 16,432,802,292 kilometers, equivalent to 109.846499 Astronomical Units. Light takes 15 hours, 13 minutes and 33.9283 seconds to travel from Pioneer 11 and arrive to us.
The following chart shows the distance of Pioneer 11 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 Pioneer 11 from Earth is also available as a real time updated value in the Live Position and Data Tracker.
Closest Approach of Pioneer 11 to Earth
Between 1 January 2013 and 31 December 2049, the closest approach of Pioneer 11 to Earth happens on Mon Jun 10 2013 at a distance of 85.782159 Astronomical Units, or 12,832,828,327 kilometers:
NOTE: values for the closest approach are computed with a sampling interval of 1 day.
Visualization of Pioneer 11 Orbit
This 3d orbit diagram is a feature of our 3D Solar System Simulator and shows the orbit of Pioneer 11 with respect of the Sun and the orbits of the major planets. The position of Pioneer 11 and the planets along their orbits in this diagram accurately represents the current configuration of the objects in the Solar System. This is an experimental feature and it requires a WebGL enabled browser. Please provide us feedback!
