The comet Lulin (center-right) is seen through the trees from Shenandoah National Park in Virginia, Monday, Feb. 23, 2009. Lulin, also known as the green comet, made its closest approach to the Earth overnight.
As Lulin comet is backward orbiting, we have to consider a problem regarding the direction of motion and a trouble in the Solar System. See my Letter in CHANGE (a bimonthly of the Carnegie Foundation for the Advancement of Teaching) May-June 2008, title: Getting science right. Personally, it reminds me of a happy discussion of that problem with Prof. Martin Perl (Nobel Laureate, Physics) in SINGAPORE, Nov. 2007, because we both love mechanics. See attached photo.
