I'm John Glenn -- the third American to fly in space and the first American to orbit earth in a space craft. In 1998 I became the oldest person to fly in space (I was 77).
I just saw Pluto pass by. It looked like he was heading back into the solar system to hide under the dense atmosphere of a planet closer to the Sun than Earth. I hope he doesn't get too hot!

Where is Pluto hiding now?
