It occurred to me that those close-in asteroids must be out of the plane of
the ecliptic. Otherwise the gravitational influence of the other close-in
planets would have messed up the orbit by now. The 2.6 to 2.8 AU asteroids
were formed by a planetary collision with something big, so that debris is
in the plane. If the asteroid is very far out of the ecliptic plane, the
amount of delta V needed to get to it is appalling. We might be able to use
the moon to get some out-of plane delta V however.
Samantha do you have a reference which gives the Atens' angle to the plane?
Did you have in mind sending actual proles out there?
