10/19/2022 – Ephemeris – Let’s search for the naked-eye planets for this week
This is Bob Moler with Ephemeris for Wednesday, October 19th. Today the Sun will be up for 10 hours and 47 minutes, setting at 6:51, and it will rise tomorrow at 8:04. The Moon, 2 days past last quarter, will rise at 2:29 tomorrow morning.
Let’s search for the naked-eye planets for this week. Jupiter and Saturn will be visible this evening, in the east-southeast and south-southeast respectively, as soon after sunset as it will be dark enough to see them, which would be by 7:45 pm. Jupiter is seen against the stars of Pisces the fish, while Saturn is spotted in the eastern end of Capricornus the sea goat. The red planet Mars, though a morning planet, will rise tonight at 9:41 pm in the northeast. It’s located between the tips of the long horns of Taurus the bull. By seven tomorrow morning, the red planet Mars will be high in the southwestern sky, above the winter constellation of Orion. Tiny Mercury might be spotted very low in the east around 7:30 am for the next few days.
The astronomical event times given are for the Traverse City/Interlochen area of Michigan (EDT, UT – 4 hours). They may be different for your location.

Telescopic views of Saturn Jupiter and Mars (north up) as they would be seen in a small telescope, with the same magnification. The image of Mars doesn’t show it, but the white north polar cap will appear at the top or north limb of Mars. Saturn and Jupiter are shown at 9 pm, Mars at 7 am. I do not show planets less than 10 seconds of arc in diameter, so Mercury is not shown. Apparent diameters: Saturn 17.61″, its rings 41.02″; Jupiter 48.82″. Mars 13.86″. Mars’ distance is 63.0 million miles (101.4 million kilometers). The ” symbol means seconds of arc (1/3600th of a degree.) Click on the image to enlarge it. Created using Cartes du Ciel (Sky Charts).
