New Horizons Distance from Earth
The distance of New Horizons from Earth is currently 8,357,866,339 kilometers, equivalent to 55.868886 Astronomical Units. Light takes 7 hours, 44 minutes and 38.8412 seconds to travel from New Horizons and arrive to us.
The following chart shows the distance of New Horizons 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 New Horizons from Earth is also available as a real time updated value in the Live Position and Data Tracker.
Closest Approach of New Horizons to Earth
Between 1 January 2013 and 31 December 2024, the closest approach of New Horizons to Earth happens on Tue Jun 4 2013 at a distance of 25.550327 Astronomical Units, or 3,822,274,576 kilometers:
NOTE: values for the closest approach are computed with a sampling interval of 1 day.
Visualization of New Horizons Orbit
This 3d orbit diagram is a feature of our 3D Solar System Simulator and shows the orbit of New Horizons with respect of the Sun and the orbits of the major planets. The position of New Horizons 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!
