Voyager 1 is currently so far away that a radio signal traveling at the universal speed limit the speed of light takes over 23.6 hours to reach it. If you sent a "ping" to the spacecraft right now, you would not get a reply until the day after tomorrow.
Despite being launched nearly half a century ago, these twin explorers are still screaming through the dark, and we have the fresh data to prove exactly where they are two tiny machines adrift beyond the edge of our solar system entirely.
What are the Voyager probes and why do they still matter in 2026?
Launched in 1977, Voyager 1 and Voyager 2 were originally designed for a four-year "Grand Tour" of the outer planets. They turned blurry dots in our telescopes into living worlds giving humanity its first close-up views of Jupiter's Great Red Spot, Saturn's ring structures, and the eerily smooth surface of Europa.
Today, they have transitioned from planetary explorers to interstellar scouts, acting as our only instruments operating outside the Sun's direct influence. The Voyager missions represent the longest-running and most distant human experiment in history.
Where is Voyager 1 now in 2026? The live numbers
As of May 2026, the distances these machines have covered are difficult for the human brain to process without a reference frame. Scientists measure these distances in Astronomical Units (AU), where 1 AU is the average Earth–Sun distance of approximately 149.6 million kilometres.
- →Voyager 1: approximately 170.5 AU from the Sun (25.5 billion kilometres)
- →Voyager 2: approximately 142.8 AU from the Sun (21.4 billion kilometres)
To put that in perspective, if you were driving a car at 100 km/h non-stop, it would take you roughly 29,000 years to reach Voyager 1's current position. At these distances, the Sun is no longer a warming disk it is merely the brightest star in a very dark sky.
To make these numbers even more visceral, consider this comparison for Voyager 1's current distance of 170.5 AU:
| Mode of Travel | Time to reach Voyager 1(Approx.) |
|---|---|
| Walking (5 km/h) | ~860,000 years |
| Car (100 km/h) | ~29,000 years |
| Commercial jet (900 km/h) | ~3,200 years |
| New Horizons spacecraft | ~78,000 years |
| Speed of light | 23.6 hours |
The table above is not a typo. Even travelling at the fastest speed physically possible in this universe, you would still spend nearly a full day in transit. And Voyager 1 is getting farther away at roughly 17 kilometres every single second faster than any bullet ever fired, faster than any aircraft ever built, yet still achingly slow against the true scale of interstellar space.
Voyager 2 is no slouch either, currently sitting at 142.8 AU approximately 21.4 billion kilometres from the Sun and moving at around 15 kilometres per second. The fact that two machines built with 1970s transistor technology are still in motion, still communicating, and still scientifically relevant nearly 50 years after launch is one of the quiet miracles of human engineering.
How I plotted their position using NASA JPL Horizons data
To create the visualisation below, I did not estimate or guess I pulled the vectors directly from the NASA JPL Horizons system
using a Python library called astroquery. This system provides the most accurate real-time ephemeris data available the precise position and velocity of every significant object in our solar system, updated continuously.
By querying the Horizons API for Voyager 1 (NAIF ID: -31) and Voyager 2 (NAIF ID: -32), I extracted their Cartesian coordinates relative to the Sun in AU. The plot below shows a heliocentric top-down view of the solar system, with both probes marked at their exact May 2026 positions. The subtle curves in their paths reflect the gravitational bends from planetary flybys decades ago permanent signatures of encounters with worlds they will never visit again.

Why their trajectories look so different
If you look at the plot above, you will notice the two probes are not travelling together they are heading in entirely different directions, separated by tens of AU. The reason traces back to deliberate choices made by mission planners in the late 1970s.
The Titan encounter is worth dwelling on for a moment, because it was a genuine fork in the road. Scientists had to choose between sending Voyager 1 closer to Saturn's moon Titan for a detailed atmospheric study, or keeping it on a path that would allow a later Uranus flyby. They chose Titan, and that encounter flung the spacecraft sharply above the ecliptic plane ending its planetary tour but giving it the fastest escape velocity of any object humanity had launched at that time.
Voyager 2 took the road less travelled. By threading a precise gravitational needle at Saturn, it became the only spacecraft in history to visit all four gas giants in a single mission. Each planetary flyby acted like a slingshot, stealing a tiny fraction of each planet's orbital momentum and converting it into raw spacecraft speed. By the time Voyager 2 departed Neptune in 1989, it was travelling fast enough to escape the Sun's gravity entirely a feat that would have been impossible with the rocket technology of the era without these carefully choreographed encounters.
Because the two probes are exiting the heliosphere at different angles, Voyager 1 heading north of the ecliptic toward the constellation Ophiuchus, Voyager 2 diving south toward Pavo and Indus NASA is effectively sampling the solar system's boundary from two latitudes simultaneously. Think of it as having two weather stations at opposite ends of a continent rather than just one.

Crossing the heliosphere: truly in interstellar space
One of the most common questions about Voyager is whether the probes have "left the solar system." The answer depends on your definition, but for physicists, the boundary that matters is the heliopause (visible clearly in the logarithmic scale diagram above.) .
This is the region where the solar wind a continuous stream of charged particles blown outward from the Sun is finally pushed back by the pressure of gas between the stars. Voyager 1 crossed this frontier in 2012, making it the first human-made object to enter the interstellar medium. Voyager 2 followed in 2018, confirming that the heliopause is not uniform it sits slightly closer to the Sun in the southern direction.
In this interstellar medium, the probes are detecting cosmic rays far more intense than what we experience on Earth because out here, there is no solar magnetic field to deflect them. Every reading they send back is genuinely new science, from a place no instrument has ever sampled before.
Will we ever lose contact? The Deep Space Network situation
The biggest threat to the Voyagers is not the cold or the distance it is power. Their Radioisotope Thermoelectric Generators (RTGs) lose approximately 4 watts of output every year, and the budget is now critically tight.
The DSN is not a single dish but a global network of three major complexes one in Goldstone, California; one near Madrid, Spain; and one in Canberra, Australia. Spaced roughly 120 degrees apart in longitude, they ensure that as Earth rotates, at least one complex always has line-of-sight contact with any deep space spacecraft. For the Voyagers, antenna sessions are scheduled months in advance, because the 70-metre dishes are among the most in-demand scientific instruments on the planet, shared between dozens of active missions simultaneously.
The signal that arrives from Voyager 1 after its 23.6-hour journey is extraordinarily faint roughly 20 billion times weaker than the power needed to run a digital watch. NASA's receivers must distinguish this whisper from the background noise of the universe itself.
The RTG power budget is now so tight that NASA has been forced to shut down instruments one by one. Heaters that protect components from the interstellar cold hovering around minus 269 degrees Celsius have been switched off entirely on some subsystems. Engineers estimate that meaningful science data can be sustained until approximately 2025–2030, after which the transmitters themselves may not have sufficient power to bridge the distance. When that day comes, humanity's first interstellar ambassadors will go silent still moving outward, still carrying the Golden Record, but no longer able to tell us anything about the journey.
If you are interested in how NASA tracks objects much closer to home, our piece on the Apophis 2029 flyby uses similar JPL tracking techniques for near-Earth asteroids. And unlike the outward-bound Voyagers, the Parker Solar Probe holds the record for the fastest human-made object, but achieves that speed by diving toward the Sun, not away from it.
Frequently Asked Questions
How far is Voyager 1 from Earth right now?
As of May 2026, Voyager 1 is approximately 170.5 AU from the Sun roughly 25.5 billion kilometres (15.8 billion miles). Because Earth orbits the Sun, this distance fluctuates slightly, but the probe is moving away at about 17 kilometres every second.
Is Voyager 1 still sending data in 2026?
Yes. Despite technical challenges with its flight data system, NASA engineers have maintained communication. Voyager 1 continues to send back data about the interstellar medium, though instruments are being turned off one by one to conserve its decaying nuclear power source.
How long would it take to reach Voyager 1?
With current rocket technology, several decades. Even at the speed of light, the journey takes 23.6 hours. A car at 100 km/h would take approximately 29,000 years to cover the same distance.
Will Voyager ever reach another star?
In about 40,000 years, Voyager 1 will pass within 1.6 light-years of the star Gliese 445. It will not collide it will simply drift past. Space is so empty that the probability of hitting anything is essentially zero.
What is Voyager 1 made of?
Primarily aluminium and titanium, featuring a 3.7-metre high-gain antenna dish. It carries the famous Golden Record a copper phonograph disc containing sounds and images representing life and culture on Earth, addressed to any extraterrestrial intelligence that might one day find it.
Has Voyager 1 left the solar system?
It depends on the definition. Voyager 1 crossed the heliopause in 2012, entering the interstellar medium. However, it will not exit the Oort Cloud the outermost shell of icy bodies gravitationally bound to the Sun for another roughly 300 years.
