As it goes in life, the dreaded question of "Why is Pluto not a planet anymore?" showed up in my life beyond the planetarium shows. Thanks to Duncan Steel I had the chance to reply to it by grace of John Campbell, Initiator and organiser of the "Ask-A-Scientist" programme, questions@ask-a-scientist.net
So why is Pluto not a planet anymore? You can download here a copy of my reply which was kindly edited (slashed ) by Duncan to fit the 150 words requested by the newspaper format.
