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.

Distance of New Horizons from Earth between January 2013 and January 2025

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 January 2013 and January 2025, 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:

New Horizons rise and set times

Location: Greenwich, United Kingdom [change]
Latitude: 51° 28’ 47” N
Longitude: 0° 00’ 00” E
Timezone: Europe/London

Today's New Horizons rise, transit and set times from Greenwich, United Kingdom [change] are the following (all times relative to the local timezone Europe/London):

Azimuth: 110.2°
Max altitude: 18.3°
Azimuth: 249.8°

The rise and set times are defined as the time at which the upper limb of New Horizons 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 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!
