Voyager 1: The Farthest Human-Made Object in Space
Subheadline: Journey to the Unknown
Moving at a speed of 38000 mph, Voyager 1 is the farthest object created by humans. Launched in 1977, it has ventured into interstellar space and continues to explore the unknown.
As of January 2024, Voyager 1 is approximately 136 AU (15 billion miles or 20 billion kilometers) from Earth, making it the farthest human-made object from our planet. Along with its twin, Voyager 2, it has reached interstellar space, a vast region beyond the influence of our sun.
Voyager 1's journey began in 1977 when NASA launched it to study the outer planets. It made historic flybys of Jupiter and Saturn, capturing stunning images of their moons and gaseous rings. In 2012, it crossed the heliopause, the boundary between the solar wind and interstellar space.
Today, Voyager 1 continues its solitary voyage through the interstellar void. It is powered by a radioisotope thermoelectric generator, which provides a steady supply of electricity. The spacecraft's instruments continue to collect data on the space environment, including cosmic rays, magnetic fields, and interstellar particles.
