Scientists using a high-powered telescope in Chile have been able to measure Pluto's orbit precisely, to help with navigation as a US probe nears the planet in 2015.

This will help Nasa's New Horizons craft home in on its target, according to scientists at the US National Radio Astronomy Observatory, adding that the Atacama Large Millimeter/submillimeter Array, or ALMA, in Chile had made it all possible.

The dwarf planet was discovered back in 1930, but due to the enormous distance between earth and it, scientists until now had major problems finding its exact orbit and location.

That's because while the earth takes a year to orbit the sun, it takes Pluto 248 of our years to complete one trip around the sun.
