New Horizons is travelling outward through the outer Solar System, beyond its Pluto and Arrokoth encounters. It flew past Pluto; it did not stay in orbit around it.
Timestamped calculated positions, not spacecraft telemetry. This panel stays on current data when you explore historical dates in the map.
Today: explore the spacecraft's current outward journey. Milestone views use dated JPL samples when available.
Historical map views show a date snapshot and a sampled trajectory, not an exact encounter replay. The displayed map timestamp identifies the loaded epoch.

An educational simulation; this does not transmit a signal.
Estimate = sampled Earth distance ÷ 299,792.458 km/s. The round trip is approximately twice that value. Motion during transit, processing time and ground-station scheduling are excluded. Older samples are labelled and cannot start a new simulation.
Pluto continues moving around the Sun while New Horizons follows a different trajectory. Distance from Pluto is the direct separation between them at the stated time; subtracting their distances from the Sun would not give that separation.
The mission timeline connects three different investigations: Jupiter's gravity assist, Pluto and its moons, and the small Kuiper Belt world Arrokoth. Use the buttons above to examine those dates, then choose Today to return to the current map.

TRACKER GUIDE & MISSION EXPLAINER
New Horizons transformed Pluto from a distant point of light into a complex world and later completed the first close exploration of a Kuiper Belt object. The tracker above uses JPL Horizons ephemerides to show the spacecraft's continuing outward journey, current distances and Sun-centred vector.
NASA launched New Horizons on January 19, 2006. It flew past Jupiter for a gravity assist in 2007, reached Pluto on July 14, 2015 and passed the Kuiper Belt object Arrokoth on January 1, 2019.
The Pluto encounter mapped diverse terrain including mountains, glaciers and the bright heart-shaped region dominated by Sputnik Planitia. The spacecraft also studied Pluto's moons and atmosphere. Arrokoth revealed a contact-binary world that preserves information about early Solar System formation.
New Horizons is now travelling through the Kuiper Belt and outer Solar System. Its path differs from both Voyagers, so distance alone should not be used to imagine the spacecraft lined up in one direction.
Horizons produces position and velocity vectors for the spacecraft at requested epochs. The site caches a short series and interpolates the display. Earth distance varies with annual geometry, while Sun distance shows the long-term outward trend more directly.
The graphic compresses scale so that the Sun, Earth and spacecraft can be seen. Numeric values and the stated reference frame matter more than apparent spacing in the illustration.
The mission is a clear example of reconnaissance: a fast flyby must collect data during a brief encounter and can take months to transmit the complete dataset home. It also demonstrates that the Kuiper Belt is a broad population of icy bodies, not a narrow ring at one distance.
NASA reported New Horizons awakening from a long hibernation in 2026 at billions of kilometres from Earth. Mission updates should be consulted for current operational details; the tracker concerns ephemeris position.
The page does not receive spacecraft telemetry or indicate instrument activity. The vector and distance are calculated ephemeris values, and the scene is not a literal scale model.
New Horizons carried a compact suite of cameras and particle instruments, but the radio link from Pluto was slow compared with modern terrestrial networks. The spacecraft stored encounter data and transmitted it over many months. As distance increases, received signal strength falls and light time grows, making careful scheduling essential. The tracker's distance readout provides the physical reason for those constraints and shows why a successful flyby includes years of planning before encounter and long analysis afterward.
MISSION REFERENCE · RESEARCH & TRAJECTORY
New Horizons flew past Pluto and its moons in July 2015 after a Jupiter gravity assist earlier in its cruise. The close encounter transformed Pluto from a small, distant point of light into a world with varied terrain and atmosphere-related phenomena. On January 1, 2019 the spacecraft flew past Arrokoth, a small Kuiper Belt object. These two encounters were different types of investigation: one examined a dwarf-planet system, the other a primitive body whose structure offers clues about how small objects assembled early in Solar System history.
A spacecraft travelling at high relative speed cannot stop for a close look without an enormous change in momentum. New Horizons instead used preplanned observations on approach, at closest passage and while departing. Pointing, lighting and transmission opportunities mattered as much as the closest-distance number. A live trajectory plot today cannot reproduce the exact camera view of a past encounter. For historical images and discoveries, use NASA’s New Horizons mission archive alongside the position tracker.
The spacecraft’s distance from the Sun tracks its outward journey in broad terms, while distance from Earth also reflects Earth’s yearly orbit. One-way light time expresses the unavoidable signal delay. It is not the time a spacecraft needs to travel the remaining distance to another object. The 3D view uses compressed spatial scale so users can keep both the inner planets and a distant probe on screen; rely on numerical values for precise comparisons. Observer sky coordinates provide a calculated line of sight rather than a practical naked-eye target.
Beyond its primary encounters, New Horizons can investigate its distant environment and observe Kuiper Belt objects under favourable conditions. Its actual observing plan depends on mission operations, available power and communications windows. The word ‘live’ on this site refers to updated ephemeris calculations; it does not mean that every displayed spacecraft is streaming pictures or science data continuously. NASA publishes mission news when new data are returned and interpreted.
No. It flew past Pluto in 2015 and continues outward through the Kuiper Belt and outer Solar System.
Arrokoth is a Kuiper Belt object that New Horizons flew past on January 1, 2019.
The high-speed trajectory enabled a relatively rapid journey; entering Pluto orbit would have required a very large reduction in speed.
No. It displays JPL Horizons ephemeris-derived position and interpolated values.
