New here, asteroids prefered

Brooks,

I am not too sure you are correct. Have a look at the orbit of this
asteroid:

http://www.jpl.nasa.gov/news/news.cfm?release=2010-115

Assume that its orbit has to be corrected by just 10 degrees, and it has a
velocity of 20 Km / s

You will need to apply a lateral delta v of 20 tan 10degrees to affect this
correction.

That works out to 3.5 Km/s

I think we will need to work out a particular case to gain confidence that
it is possible to capture an asteroid with very low expenditure of delta v.
Also, dynamic braking can be done using the atmosphere of the Earth, since
the Moon has no atmosphere, it cannot be used for this purpose.

(Those of you who may not be aware, google search engine seem to be better
than excel for doing calculations. Just enter tan 10 degrees *20 into your
search query and hit 'Enter').

Selvaraj
