The best time to see the planet Saturn in 2013 is now! Saturn will be out nearly all night for most of May. Why is Saturn so good to view this month? The reason is that we passed between Saturn and the sun in late April. At that time, Saturn was opposite the sun as seen from Earth. Now Earth has moved on slightly in its orbit, so that Saturn appears in our eastern sky as soon as darkness falls.
