Description

Jupiter and Saturn continue to converge in the night sky and are now in reach of the C14. The sky was very clear, but seeing was very turbulent to the point of Jupiter twinkling slightly.

While the two gas giants are close together in the sky, they are physically far apart, only appearing next to each other because they and Earth are aligned in a nearly straight line. When taking this photo, Jupiter was 885 million kilometers away while Saturn was 1.8x farther at 1619 million kilometers.
