It's a Great Time to Look at Saturn (February 1, 2006)

If you've got a telescope, get out in the yard and catch a look at Saturn while the viewing is still good. The planet is closer to Earth right now than it will be at any other time in 2006.

Early this week, Saturn was at opposition to Earth. At opposition, a planet is on one side of Earth and the Sun is on the other, with the three forming a straight line. At opposition, Saturn was "only" 755 million miles (1,215 kilometers) from Earth.

Because the Sun's rays shine directly on a planet at opposition, Saturn will shine brightly in the night sky. These days, it's brighter than any star in the sky except Sirius and Canopus.

Another bonus is the tilt of Saturn's rings. Soon, the rings will be tilted at 20 degrees relative to Earth, making for excellent viewing. The rings won't be tipped this much again until 2014.

Currently, Saturn rises in the East at sunset. It peaks high in the southern sky around midnight and sets in the west at sunrise. Happy viewing!
