"Planet Triangle"
Day 138
May 27, 2013
Just after sunset on May 27, three planets formed a triangle in the sky. The three planets were Venus, Mercury, and Jupiter.  I took this photo a day after the three planets were the closest together. In this picture, the planets are still close together. 
The clouds were thin on May 27, so I was able to take a picture of Venus, Mercury, and Jupiter behind the glowing pink clouds of the sunset.
