01/25/2023 – Ephemeris – Let’s see where the naked-eye planets have wandered off to this week

January 25, 2023 Comments off

This is Bob Moler with Ephemeris for Wednesday, January 25th. Today the Sun will be up for 9 hours and 32 minutes, setting at 5:41, and it will rise tomorrow at 8:08. The Moon, 3 days before first quarter, will set at 10:42 this evening.

Let’s see where the naked-eye planets have wandered off to this week. Very early after sunset, Venus might be spotted very low in the southwest by a little past 6 pm. Mars, and Jupiter will be visible this evening, in the east to southwestern sky by 6:30 or 7 pm. Mars will be above Orion in the east-southeast and is pulling away from the Pleiades. Jupiter is brighter than Mars, and will be in the south-southwest, and tonight it’s directly above the crescent Moon. Saturn is below Venus now, so it’s pretty much gone until it reappears in the morning sky in a few months. Mercury is now in the morning sky, after it passed inferior conjunction with the Sun on the 7th, that is, it passed between the Earth and the Sun. It should be briefly visible before sunrise by month’s end.

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.


All the evening planets before Venus sets are in this panorama looking southward from east to west at 7 tonight, January 25, 2023. I dropped lines from some of the dimmer constellations. Click on the image to enlarge it. Created using Stellarium.
The waxing crescent Moon, tonight, January 25, 2023, as it might be seen in binoculars or a small telescope. Created using Stellarium, LibreOffice Draw and GIMP.
Telescopic views of Venus, 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. The planets are shown at 7 pm tonight, January 25, 2023. Apparent diameters: Venus 10.95″; Jupiter 36.63″, Mars 11.38″. Mars’ distance is 76.5 million miles (123.1 million kilometers). The ” symbol means seconds of arc (1/3600th of a degree.) Created using Cartes du Ciel (Sky Charts).
