Pioneer 11 Distance from Earth

The distance of Pioneer 11 from Earth is currently 15,615,371,621 kilometers, equivalent to 104.382312 Astronomical Units. Light takes 14 hours, 28 minutes and 7.2731 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 January 2013 and January 2050, 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.

Pioneer 11 rise and set times

Today's Pioneer 11 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 Pioneer 11 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.

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!
