See the moon and Saturn shine side-by-side in the night sky tonight

Tuesday evening (Sept. 26) will bring us a fine opportunity to make a positive identification of what many consider to be the most beautiful of all telescopic objects, the ringed planet Saturn.

And, in fact, another celestial body will help point the way to it: the moon, which will be in its waxing gibbous phase that same night.

As I have noted over the years here at, to the unaided eye, Saturn does not possess any outstanding features that call attention to it. It lacks the dazzling, eye-popping brilliance of Venus or Jupiter and it does not have the fiery orange-yellow of Mars.  

In fact, to the human eye, Saturn appears as nothing more than a very bright "star" that shines with a yellowish-white glow. Most people presently looking around the early autumn sky might even take note of this sight as they look one-quarter of the way up from the southeast horizon to a point directly overhead at around 8 p.m. local daylight time, not knowing they are looking at the solar system's ringed wonder.

But on Tuesday, the moon will be situated to the lower right of Saturn.  

If it is clear, that evening will be a great night to invite your friends and neighbors over to peer through your eyepiece at both Saturn and our nearest neighbor in space; two wonderful sky objects.  

First, the moon

First, you'll want to check out the moon. A full moon looks "flat" and one-dimensional, though  its brilliance may dazzle the eye. But Tuesday’s moon won't be quite full, but rather 92 percent sunlit. It will also shine about half as bright as it would if full. Moreover, check out the region along the terminator — that part of the moon that separates the light zone from the dark zone. Take note especially of a rather brightly lit crater situated adjacent to the terminator on the upper part of the moon. That's Aristarchus, an impact crater considered to be the brightest of all large formations on the lunar surface. 

Then, check out the lower part of the lunar disk, which falls immediately along the terminator and you will see many craters casting shadows that make them dramatically stand out.

Next comes Saturn 

After you are done showing off the moon to your friends, it will then be time to turn your telescope toward Saturn. 

Your clenched fist at arm's length is equal to roughly 10 degrees — Saturn will be situated less than "half a fist" (4 degrees) to the upper left of the moon.  

Any telescope with an eyepiece magnifying at least 30-power will reveal the planet's famous ring system, which is currently tilted 10-degrees toward our planet. The best views of Saturn will depend on the size of your telescope. My recommendation is not to use your telescope's highest power (which can magnify turbulence in the atmosphere and make the image appear to "boil" or "quiver"), but a more moderate magnification. With a 3-inch telescope, try 75-power; with a 6-inch, 150-power; and with a 10-inch, 250-power. 

Even for experienced, seasoned observers, the sight of Saturn's rings in a moderate or large telescope still brings surprise and astonishment!

A final "gee-whiz" fact you can reveal to your friends is that what you are seeing in Tuesday’s sky is an illusion of perspective. The moon and Saturn are nowhere near each other in space. The moon will be 222,900 miles (358,500 km) from Earth as you view it, while Saturn will fall more than 3,700 times farther away at 827 million miles (1.331 billion km) from your vantage point.
