The outermost world
About three billion miles away (the distance varies due to the eccentricity of its orbit), Pluto is about thirteen thousand times more distant from us than the Moon is. It has taken the probe nine and a half years to get there from Earth.
Looking at Pluto's surface features, we're seeing things which (as far as we know) no eye has ever seen before.
The mission page is here; new pictures and information are being posted as they come in.
