01/26/2022 – Ephemeris – Evening planets? Then there was one.

January 26, 2022 Comments off

This is Bob Moler with Ephemeris for Wednesday, January 26th. Today the Sun will be up for 9 hours and 35 minutes, setting at 5:43, and it will rise tomorrow at 8:07. The Moon, 1 day past last quarter, will rise at 3:37 tomorrow morning.

Let’s search for the naked-eye planets for this week. There is just one planet left in the evening sky now. Jupiter will be visible in the southwest by 6:15 pm. Jupiter will set at 8:12 pm. Saturn is too close to the Sun to be seen, and will cross behind the Sun in 9 days to enter the morning sky. In the morning sky, Venus, our brilliant morning star, and the much dimmer Mars will rise about the same time about 6:05 am. Both will appear low in the southeastern twilight by 7 am. Mars will be to the right of Venus by 11 and a half degrees, about the width of a fist held at arm’s length. Mars’ rival in color and brightness, the red giant star Antares, is to its right and a bit higher, and nearer the waning crescent Moon.

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.

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 26/27, 2022. I do not show planets less than 10 seconds of arc in diameter. Apparent diameters: Jupiter, 33.85″. Mars is not shown, its apparent diameter is 4.27″. Venus has an apparent diameter of 52.85″ and is 11.0% illuminated. The ” symbol means seconds of arc (1/3600th of a degree.) Created using Cartes du Ciel (Sky Charts).
