[Utah-astronomy] Size Comparisons of the 14 Asteroids and Comets we've visited

Here is a visual link to the 14 comets and asteroids we've visited: http://www.planetary.org/image/asteroids_comets_sc_0-000-100_2010_2.png Hartley is on there, very small off to the right. I thought this was interesting to see them all lined up like this. The article I got it from says we've only been to 14 asteroids and comets and that kinda of shocked me.
