Voyager 1 and 2: Exploring the Outer Reaches of Our Solar System
Subtle Changes in Distance
As Earth orbits the Sun at varying speeds, the distance between Earth and the Voyager 1 and Voyager 2 spacecraft fluctuates. This is because Earth's orbital velocity is faster than the spacecraft's travel speed. The distance between Earth and each spacecraft changes by approximately 1468800 kilometers (nearly 5 light seconds) every day, a distance roughly four times the Earth-Moon distance or 36 times the speed of light.
One-Way Light Travel Time
Due to the fluctuating distance, the one-way light travel time between Earth and each Voyager spacecraft also varies. The signal takes approximately 22 hours and 33 seconds to reach each spacecraft.
Voyager's Journey
As of April 30, 2024, Voyager 1 had been traveling in space for 17032 days and was approximately 16319 astronomical units (AU) from the Sun, equivalent to roughly 2441 billion kilometers. Both Voyager 1 and Voyager 2 successfully explored Jupiter, Saturn, Uranus, and Neptune before embarking on their interstellar journeys.
