CAPE CANAVERAL, Fla. (AP) -- NASA's Voyager 1 has traveled farther from Earth than any other spacecraft. It's a mind-boggling 12.9 billion miles away, 40 years after its launch.

A list of the world's most distant spacecraft, according to NASA. All flew from Cape Canaveral.

---

1. Voyager 1 at 12.9 billion miles distant. Launched Sept. 5, 1977. Only spacecraft to reach interstellar space.

2. Pioneer 10 no longer communicating at an estimated at 11.1 billion miles distant. Launched in 1972.

However, the science and knowledge these spacecraft have delivered far surpasses their costs.

Keep up the great work, NASA.

Thanks for the link, Judi Lynn! Enjoy your weekend.

is that 12.9 bln miles only equals 0.0022 of a light year...With the nearest stars about 4 ly away, another 79,960 years should do it. Not that they're pointed that way.
