The most distant manmade object from Earth is Voyager 1. Launched by NASA on September 5, 1977, Voyager 1 is now in interstellar space, having crossed the heliopause (the boundary of the Sun’s influence) on August 25, 2012. As of May 2025, Voyager 1 is approximately 166.4 Astronomical Units, or roughly 24.9 billion km (15.5 billion miles) away from Earth.

Voyager 2, its twin probe, is the second-most distant human-made object. Voyager 1 continues to operate, sending back scientific data despite its great distance, and holds the record for the most distant craft for the foreseeable future. However, its onboard power source (radioisotope thermoelectric generators) is rapidly depleting.

By around 2025, its 50th anniversary, most of its systems will be shut down, likely ending communication with Earth. Even when it can no longer transmit, the spacecraft will continue its journey out of our solar system. Its next milestone will be to reach one light day from Earth, which is projected to happen in November 2026.

It is expected to enter the theorized Oort Cloud, a region of icy bodies at the edge of our solar system in the next 300 years. In about 20,000 years, Voyager 1 will pass through the Oort Cloud, fully leaving the Sun’s domain. About 40,000 years from now, Voyager 1 will pass within 1.6 light-years of the star Gliese 445, in the constellation Camelopardalis. 300,000 years into the future, it will pass within less than 1 light-year of the star TYC 3135–52–1.

Voyager 1, along with Voyager 2, will orbit the Milky Way galaxy, oscillating above and below its disk. Depending on events such as galactic mergers, these spacecrafts could be ejected or further altered by cosmic events, but if undisturbed, they could survive for trillions of years, drifting through space.

Its Golden Record, an analog message to extraterrestrial life, could theoretically survive for billions of years, protected from most cosmic hazards except rare collisions with dust or high-energy radiation. After star formation in the universe ceases, Voyager 1 could drift in a galaxy dominated by black holes, neutron stars, and white dwarfs, the remnants of a cosmic age far removed from our own. “The Voyagers are destined – perhaps eternally – to wander the Milky Way.” (NASA/JPL) References (2025, August 25).
