Why Pluto?

Humans have spent almost a decade getting a spacecraft, New Horizons, all the way to Pluto – but why did we go to so much effort? Nature Video takes a look at the history of this famous 'non-planet' and asks why it is that we care so much about Pluto.

Thank god we've got great pictures of Pluto now. Just think of how this breakthrough will benefit humanity. Just the breakthrough we've been needing to launch a new round of Millennium Development Goals.

I am so excited re Pluto visit and New Horizons journey! so far all has gone to plan and I have a good feeling that we are about to see Pluto and it's Moons in all it's glory. We are about to see and understand more about our Planet's and who know's what else!! Please scatter Clyde's ashes whilst orbiting Pluto, that would make my long wait much more exciting.. :))

Pluto is not a planet. It’s a “dwarf PLANET”. But that’s still a PLANET. Because your still using the word PLANET in reference to it. Do you see how sometimes smart people can be really dumb. So how many planets are currently in our solar system? 16

Why is there a Persian magazine behind that lady?

Nine HOURS to communicate... Are you sure it'll go fine ???

Pluto was a planet until it was too small so it was considered to not be one

Pluto doesn't belong to the planet category, get it over with
It hasn't "cleaned its orbit and surroundings"; it has nothing to do with size
