09/07/2022 – Ephemeris – Let’s search for the naked-eye planets for this week
This is Ephemeris for Wednesday, September 7th. Today the Sun will be up for 12 hours and 56 minutes, setting at 8:08, and it will rise tomorrow at 7:13. The Moon, 3 days before full, will set at 4:33 tomorrow morning.
Let’s search for the naked-eye planets for this week. Two of the naked-eye planets are in the evening sky. Mercury sets too close to the Sun to be seen in the evening. But as it gets darker, Saturn can be seen low in the southeast. Jupiter rises in the east around 8:52 pm. It is seen against the stars of Pisces now, moving slowly retrograde or westward. At 6:30 am tomorrow the three remaining morning planets will be spread out from brilliant Venus very low in the east-northeast to Mars high in the south-southeast above the bright reddish star Aldebaran to Jupiter in the west-southwest. Mars is among the stars seen rising on late autumn and winter evenings. Venus is actually all the way to the spring constellation of Leo the lion.
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 times vary for each planet. Jupiter is shown twice, at 10 pm and 6:30 am, since its moons, especially Io and Europa, move rapidly. I do not show planets less than 10 seconds of arc in diameter, so Venus doesn’t show up yet. Coincidentally, Mars has reached that threshold. Apparent diameters: Saturn 18.58″, its rings 43.23″; Jupiter 49.27″. Mars 10.23″, 85.5% illuminated; Venus (not shown) 9.97″, 97.9% illuminated.

Let’s search for the naked-eye planets for this week. Two of the naked-eye planets are in the evening sky. Mercury probably sets too close to the Sun to be seen in the evening, but it might be spotted very low on a Lake Michigan horizon in the west at 9 pm. As it gets darker, Saturn can be seen low in the southeast. Jupiter rises in the east around 10 pm. At 6:15 am tomorrow, the morning planets will be spread out from brilliant Venus low in the east-northeast, and below the thin crescent Moon to Jupiter in the southwest. Mars, in the southeast, will be a lot higher than both Venus and Jupiter. Mars is among the rising stars seen in the late autumn and winter evening skies, when observing them then, it will be a lot colder than it will be tomorrow morning.

Mercury as it might appear at 9:05 pm tonight, August 24, 2024. I’ve included nearby Spica, which is easier to spot at that time. Actually, neither is likely to be visible. Mercury is only 2 1/2 degrees above a sea horizon. Created using Stellarium.
