Around a billion large comets falling in from the Oort cloud would be needed. Better just to use all of the Sun's radiant energy over the course of a year in order to disassemble it and build a Niven ring :-).Travis Garretthttps://www.blogger.com/profile/03688488356753064225noreply@blogger.comtag:blogger.com,1999:blog-3722233.post-1115135103913687422005-05-03T10:45:00.000-05:002005-05-03T10:45:00.000-05:00Venus' rotation is somewhat unusual in that it is ...Venus' rotation is somewhat unusual in that it is both very slow (243 Earth days per Venus day, slightly longer than Venus' year) and retrograde.<BR/><BR/>From <A HREF="http://www.nineplanets.org/venus.html" REL="nofollow">here</A>.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-3722233.post-1115132424283332972005-05-03T10:00:00.000-05:002005-05-03T10:00:00.000-05:00If such a program actually worked, how should a pr...<I>If such a program actually worked, how should a program be used, if at all?
