Distant, small objects

How many small planets (asteroids?) do you think they've now discovered way beyond the orbit of Pluto and Neptune?    840, apparently, which does seem a lot to me.

And one will be visited next year by that New Horizons probe that went past Pluto last year.  

Speaking of that probe, there was a talk by the NASA folk who worked on it on Radio National last week (in the Big Ideas series.  Here's a link to the podcast.)   It was very interesting.
