01/19/2022 – Ephemeris – Let’s search for the naked-eye planets for this week

January 19, 2022 Comments off

This is Ephemeris for Wednesday, January 19th. Today the Sun will be up for 9 hours and 19 minutes, setting at 5:33, and it will rise tomorrow at 8:13. The Moon, 2 days past full, will rise at 7:15 this evening.

Let’s search for the naked-eye planets for this week. There are two planets left in the evening sky now. Jupiter will be visible in the southwest by 6:15 pm. Saturn might be visible below and right of it, much closer to the Horizon. Finding Saturn might require the use of a pair of binoculars. Saturn will set at 6:44, while Jupiter will set at 8:22 pm. In the morning sky, Mars will rise at 6:10 am while Venus, our brilliant morning star, will rise at 6:40 am. Both will appear low in the southeastern twilight by 7:15. Mars will be to the right and a bit higher than Venus. Mars’ rival in color and brightness, the red giant star Antares, is to its right and a bit higher. Another bright star is low in the east at that time, the summer evening star Altair.

The astronomical event times given are for the Traverse City/Interlochen area of Michigan (EST, UT – 5 hours). They may be different for your location.

Addendum

Jupiter and Saturn in the evening

Jupiter and Saturn at 6:15 pm, about 45 or so minutes after sunset over an unobstructed horizon. Jupiter will be quite bright in twilight, while Saturn may require binoculars to find. Created using Stellarium.

Binocular Moon

The waning gibbous Moon as it might appear in binoculars or small telescope at 8 pm (about 45 minutes after rising) tonight, January 19, 2022. Created using Stellarium.

Venus and Mars in the morning

Venus and Mars as they might appear at 7:15 am, about an hour before sunrise tomorrow morning, January 20, 2022. At that time, the waning gibbous moon will appear in the west. Click on the image to enlarge it. Created using Stellarium.

Telescopic views of Jupiter, Saturn and Venus

Telescopic views of the bright planets and their brighter moons (north up) as they would be seen in a small telescope, with the same magnification, overnight, January 19/20, 2022. I do not show planets less than 10 seconds of arc in diameter. Apparent diameters: Saturn 15.29″, its rings 35.63″; Jupiter, 34.19″. Mars is not shown, its apparent diameter is 4.19″. Venus has an apparent diameter of 58.07″ and is 5.2% illuminated. The ” symbol means seconds of arc (1/3600th of a degree.) Created using Cartes du Ciel (Sky Charts), though Venus’ image was enhanced in GIMP.

Planets and the Moon on a single night
