neil, al tombaugh. i'm clyde's son. tyson: al, pleasure. and this is my mother, patricia tombaugh. this is clyde's wife. it is an honor hello. yes, i've been looking forward to this. that could be... i don't know what that means. (all laughing) so, tell me about clyde as a person. he was the oldest of six children, so he was born to help on the farm. but he did not want to be a farmer. annette: he had not had the opportunity to go to college. so what you're saying is that he discovered pluto without ever having yet gone to college. no, he was straight off the farm. patricia: lowell observatory wanted somebody they didn't have to pay very much to do this job. what do you think they pay you for finding a planet? (all laughing) annette: after discovering pluto, he got a college scholarship which he would not have otherwise had, and, of course, he was supposed to be the big hero but he didn't feel like the big hero. dad was a little embarrassed about the fame. he didn't like the limelight. he was humble. absolutely. so what was he like just as a dad? was he like a weird dad? or did you

perhaps the most sentimental and noteworthy are some of clyde tombaugh's ashes. his ashes.t's on its way to the stars. the man is on his way back to the very planet he discovered and he's due to arrive there in 2015... that's great. and that just blows my mind. i'd challenge anybody to put that on their résumé. tyson: finally its time to head back home. but my journey isn't quite over. i have one more thing to do, a promise to keep. when i met annette tombaugh, she told me she had never seen our exhibit and asked if she could see it with me. of course i agreed. i was a little nervous about inviting annette to the rose center, because this is kind of where the public awareness of the problems with pluto began. i'm excited. i'm really excited about seeing the exhibit. of course i am still going to look for pluto. i think what we did here is sensible. so let's hope this works. (knocking on glass door) (laughing) hello. hi! welcome to new york. it's good to see you. oh, my goodness. welcome to the belly of the beast. tyson: i showed annette where we exhibit the planets. then i
