September: Mercury and Spica Align

The blue-white star Spica 270 light years away aligns with Mercury 9 light minutes away. Click on image to enlarge.

They're only 4.3 arcminutes (0.07°) apart in this image taken 22 Sep 2007 from South Australia. Next time they are this close together will be in 2040.
