Approaching One Light-Day

On Wednesday, Nov. 18, 2026, at 2:16:07 a.m. PST, NASA’s Voyager 1 spacecraft will be 16,094,799,096 miles (1,079,252,848 kilometers) away from Earth — or, the distance light travels in 24 hours, also known as one light-day.  

Voyager 1 will be the first human-made object to reach this distance from Earth, adding to a long list of historic firsts for the mission. Voyager 1 and its twin, Voyager 2, are the only spacecraft to ever operate outside the heliosphere, or the protective bubble of particles and magnetic fields generated by the Sun. 

Track the Voyagers’ progress through the cosmos with the interactive tools below.

Voyager 1 — Current Position

Use Eyes on the Solar System, NASA's 3D interactive visualization tool, to see where Voyager 1 is at this moment. Or, use the controls to see where it's going, or anywhere that it's already been since 1977, on its journey from Earth, past Jupiter and Saturn, to interstellar space.

Voyager 2 — Current Position

Use Eyes on the Solar System, NASA's 3D interactive visualization tool, to see where Voyager 2 is — right now. Or, use the controls to see where it's going, or anywhere that it's already been since it launched in 1977, left Earth for its Grand Tour of Jupiter, Saturn, Uranus, and Neptune, then headed for interstellar space.

Maintenance note: The Voyager “Mission Status” table is temporarily offline while we fine-tune the numbers to match the latest mission data. As Voyager 1 closes in on one light-day later this year, precision matters!
