See Saturn Near the Moon in the Night Sky Tonight! Here's How

Saturn has been looking stunning lately, and it's preparing to dance close to the moon to display an incredible celestial illusion.

Late tonight (June 18), what are probably the top two objects that people want to look at through a telescope will be visible low in the east-southeast sky: the moon and the "ringed wonder" of the solar system, Saturn. Shortly after 10 p.m. local daylight saving time, you'll readily see the nearly full disk of the moon; glowing sedately like a bright yellow-white "star" to the moon's upper left will be the sixth planet from the sun.

Right now, Saturn shines at magnitude +0.2. If we compared it against the 21 brightest stars, it would rank eighth, making it just a tad brighter than the similarly hued Procyon in the constellation Canis Minor and a trifle dimmer than bluish-white Rigel in Orion.

Saturn appears bright in part because it's three weeks away from its opposition to the sun, that moment during a particular period of its visibility when a planet beyond Earth's orbit is passing closest to us. 

Another reason Saturn will appear brighter than usual is the fact that its amazing rings are still tilted toward Earth at an inclination of 24 degrees. The rings, which are composed of highly reflective particles of ice, bolster Saturn's apparent brightness. 

I have been able to glimpse the rings with very large (25 x 100) binoculars, mounted on a sturdy tripod. Through a 4-inch telescope with a magnification of 100-power, the rings can clearly be seen; with a moderately large instrument of 8-inch aperture at 200-power, the view is nothing short of breathtaking. Viewing Saturn through a 12-inch telescope at 300-power is truly a stupefying experience whether you're seeing it for the first or 10,000th time.

Taking the low road

Unfortunately, right now, Saturn never gets very high above the horizon because it is positioned against the stars of Sagittarius. That zodiacal constellation stays rather low in the southern sky for viewers at midnorthern latitudes centered on 40 degrees north.

Because the atmosphere tends to be hazier and more turbulent near the horizon, objects like Saturn tend to "boil" or "quiver" through telescopes using high power. The best time to try looking is around 2 or 3 a.m. local time, when Saturn and the moon appear almost due south and near their highest point in the sky.

Interestingly, the moon will also be close to where the sun is around the time of the December (winter) solstice. During that time of the year, it's the sun that takes a low journey across the sky, but now it's the moon's turn to take "the low road."

Check out these illusions

By early Wednesday morning (June 19), Saturn will appear to the moon's upper right and they will be separated by about 2 degrees. Considering that the moon measures a half degree across, you might assume that in the sky you'll be able to mentally image four full moons in the gap that separates them.

And yet visually, they will appear much closer — only about half that distance. That's because to the eye, the moon appears twice its actual size, appearing to subtend a full 1 degree as compared to its actual size of half a degree. So in the sky, it will appear that you'd only be able to squeeze one or maybe two moons in the gap between Saturn and the moon, but certainly not four. 

Finally, there is the illusion of perspective. Keep in mind that when you look at the moon, our nearest neighbor in space, that it will be approximately 245,900 miles (395,600 kilometers) away. Although Saturn appears to be hovering close by, it is actually more than 3,400 times farther away, at a distance of some 846 million miles (1.361 billion km).
