Pioneer 10 Distance from Earth

The distance of Pioneer 10 from Earth is currently 19,018,329,827 kilometers, equivalent to 127.129683 Astronomical Units. Light takes 17 hours, 37 minutes and 18.3198 seconds to travel from Pioneer 10 and arrive to us.

The following chart shows the distance of Pioneer 10 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 10 from Earth is also available as a real time updated value in the Live Position and Data Tracker.

Closest approach of Pioneer 10 to Earth

Between March 1972 and January 2050 the closest approach of Pioneer 10 to Earth happens on Sat Mar 4 1972 at a distance of 0.00497342 Astronomical Units, or 744,014 kilometers:

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

Pioneer 10 rise and set times

Today's Pioneer 10 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 10 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 10 Orbit

This 3d orbit diagram is a feature of our 3D Solar System Simulator and shows the orbit of Pioneer 10 with respect of the Sun and the orbits of the major planets. The position of Pioneer 10 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!
