Voyager Spacecraft Distance from Earth: Current Measurements and Historical Context

Voyager 1 Distance from Earth and Solar System

Voyager 1, launched in 1977, is now traveling through deep space at a distance of more than 13 billion miles (about 0.0022 light-years) from Earth. This immense distance means that radio signals from Voyager 1 take over 19 hours to reach Earth, highlighting just how far the spacecraft has traveled since its launch .

Voyager 1 and the Edge of the Solar System

Voyager 1 crossed the boundary where the solar wind changes from supersonic to subsonic flow—known as the termination shock—at a distance of approximately 85 astronomical units (AU) from the Sun. One AU is the average distance from the Earth to the Sun, about 150 million kilometers. After passing this boundary, Voyager 1 briefly re-entered the supersonic solar wind at about 87 AU, before continuing its journey into interstellar space 35.

Voyager 2 Distance from Earth

Voyager 2, the twin spacecraft, was measured at a distance of 3 x 10^9 kilometers from Earth during a solar conjunction in 1985. This measurement was used to test the relativistic time-delay effect, confirming the vast distances these spacecraft have traveled .

Voyager Spacecraft Beyond the Solar Cavity

Since 2012, both Voyager spacecraft have been measuring cosmic radiation rates beyond the solar cavity at distances greater than 10^13 meters from Earth. These measurements have provided unique insights into cosmic electron and proton fluxes in the interstellar medium .

Conclusion

Voyager 1 is currently more than 13 billion miles from Earth, well beyond the edge of the solar system, while Voyager 2 also continues its journey through deep space. These distances are confirmed by multiple measurements and studies, demonstrating the incredible reach of human-made spacecraft and the ongoing scientific discoveries they enable 12345.

Voyager 1 exited the solar wind at a distance of ∼85 au from the Sun

Voyager 1 spacecraft experienced a large increase in energetic particles in the outer heliosphere, possibly due to the collision of anomalous cosmic rays and interstellar pick-up ions at the termination shock.
