Voyager 1 Is About One Light-Day from Earth
November 26th, 2025Via: Science Clock:
After nearly 50 years in space, NASA’s Voyager 1 is about to hit a historic milestone. By November 15, 2026, it will be 16.1 billion miles (25.9 billion km) away, meaning a radio signal will take a full 24 hours—a full light-day—to reach it. For context, a light-year is the distance light travels in a year, about 5.88 trillion miles (9.46 trillion km), so one light-day is just a tiny fraction of that.
