absolutely monster daytime coma!

In my opinion that picture is an illustration, not the physical object
An asteroid does not give of stuff like a comet which that picture is of.
At 45.000 kms the object about the size of a 10-storey building - would be miniscule, and would need a scope or a pair of good binoculars to see, depending how bright it got.
Objects like this come by every now and then an have been searched for by amateurs with various results
You obviously did not read the info properly.

doh yup cheers ron for clarifying. thanks.. thought it was a near 'snap' matching the title.

indeed a comet.

They (The Daily Galaxy) got some of their figures wrong....for instance, Chicxulub was a 100 million MT explosion, not 100MT.

Rob Mcnaughts animation of 2009DD45 is on the link below and was done on 27th February 2009 prior to closest approach to Earth on March 2nd 2009. The comet used in the article Alex refers to is almost certainly Comet McNaught C/2006P1 (The Great Comet of 2007) in the daytime (there are similar blue sky picks in links below) and not the asteroid 2009 DD45 that the article makes a reference to. Admittedly the caption notes asteroid /or comet at left without noting any designation.

Yep. That's Comet McNaught C/2006P1. I've got it in my collection for 2007. Great picture though.
