"How to Find Uranus by Using Mars, and; Watching the Full Moon Occult the Ringed Planet Saturn"

Scheduled air date: 2001 Nov 19-25

On the night of November 26, the planet Mars will be about three-quarters of a degree from the planet Uranus.  Even though Uranus is 7.5 times the diameter of Mars, it is more than 16 times farther and much fainter.  While it is possible to see Uranus with the unaided eye, this will be a good time to use binoculars or a telescope to find it.
(Shown about an 90-minutes after sunset for mid-Northern latitudes.  Inset simulates a binocular view of the region around Mars.)

On the night of November 30, the Full Moon will occult—or cover—the ringed planet Saturn as seen from Mexico and the southeastern two-thirds of the United States!  Check your local newspaper for viewing information in your area, or see details on the International Occultation Timing Association's site  at www.lunar-occultations.com/iota/1201sat.htm.
(Main image shown about an hour after sunset for mid-Northern latitudes.  Inset shows the Moon's position at one-hour intervals near the time of occultation.)
