Voyager 1, the farthest human-made object from Earth, is about to hit one light-day distance from us, or the distance that light travels in a single day. According to Science Clock, the satellite is going to be 16.1 billion miles or 25.9 billion kilometers away on November 15, 2026 — 49 years, 2 months, and 10 days since it launched. This means that the spacecraft travels at an approximate speed of 37,300 miles per hour (over 60,000 kilometers per hour) or more than 10 miles per second. At its current distance, it takes about a day to send commands to Voyager 1 and another day for it to respond.
NASA launched Voyager 1 on September 5, 1977, to explore the giant gas planets Jupiter and Saturn, as well as some of their moons, and completed this mission in November 1980. After 10 years, the space agency began the Voyager Interstellar Mission, where it would explore the space outside the vicinity of our solar system. By 2004, it had entered the space where the solar wind from the sun slows down, with the satellite entering interstellar space in 2012.
