It’s currently in the constellation Scorpius, just east of the reddish star Antares (the heart of the Scorpion). By contrast, Saturn appears “straw colored” and brighter.

Saturn takes about 30 years to orbit the Sun. The tilt angle of its rings can be anywhere from 0° (edge-on) to ± 27° as seen from Earth. As you can see in the photo above, when the rings are edge-on (as they were in 2009) they pretty much disappear. The rings are only about 1 km ...
