Thanks to a continent-wide radio telescope, astronomers say they know where Saturn is - to within one mile.
The calculation is many times more accurate than previous estimations and will be useful for the future study of our solar system and beyond.
It used signals sent by the spacecraft Cassini, orbiting Saturn since 2004.
Ten antennae scattered from Hawaii to the Virgin Islands performed the precise measurement, despite Saturn being nearly a billion miles away.
This powerful assembly is known as the Very Long Baseline Array (VLBA), a giant telescope in ten parts.
The findings were reported at a meeting of the American Astronomical Society in Seattle.
