How big is our target asteroid? 40 – 120 m in diameter they say, but what does that mean? In order to gain perspective, I brought my 30 mm wizard to the rock where my running occasionally takes me. If the wizard were me, and the rock the asteroid, then the rock resembles a 60 m asteroid (there is a little wizard on the rock in the picture).
Is that a lot, or a little? Little I guess in some perspective, it all depends what you want to do with it I guess.
