07/27/2022 – Ephemeris – Let’s search for the naked-eye planets for this week

July 27, 2022

This is Bob Moler with Ephemeris for Wednesday, July 27th. Today the Sun will be up for 14 hours and 50 minutes, setting at 9:14, and it will rise tomorrow at 6:24. The Moon, 1 day before new, will rise at 5:52 tomorrow morning.

Let’s search for the naked-eye planets for this week. All but one of the naked-eye planets are in the morning sky, That one is Mercury, too close to the Sun to be seen in the evening. At 5:30 am tomorrow, the planets will be spread out from brilliant Venus low in the east-northeast to Saturn in the southwest. Mars will be a lot higher than Venus in the east-southeast. Jupiter is farther to the right in the south. Mars is dimmer than Jupiter, but is slowly getting brighter as the Earth creeps up on it. Saturn ends the line of planets much lower than Jupiter in the southwest. Tonight, Saturn will rise about 10:06 pm, though it won’t be an official evening planet until it rises before sunset, which won’t happen until August 14th.

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.

Addendum

Morning planets at 5:30 am tomorrow

Morning planets at 5:30 am tomorrow , July 28, 2022. The planets and Moon actually appear in a straight line in the sky, being placed along the ecliptic, or path of the Sun in the sky. The ecliptic is a great circle on the celestial sphere. Click on the image to enlarge it. The span of the planets from Venus to Saturn is 140 degrees. Two of winter’s first magnitude stars, Aldebaran and Capella, are now visible in morning twilight. Click on the image to enlarge it. Created using Stellarium.

Telescopic views of Venus, Saturn and Jupiter

Views of Saturn, Jupiter, and Venus (north up) as they would be seen in a small telescope, with the same magnification, tomorrow morning at 5:30 am, July 28, 2022. I do not show planets less than 10 seconds of arc in diameter. Apparent diameters: Saturn 18.67″, its rings 43.49″; Jupiter 44.58″. Mars is not shown, its apparent diameter is 8.13″, 84.8% illuminated; Venus 10.84″, 91.9% illuminated. 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).

Noting Jupiter and moons image: Europa has just appeared from being behind Jupiter’s disk at 5:27 am (8:27 UT). It had disappeared into Jupiter’s shadow earlier at 12:23 am (4:23 UT).

Planets and the Moon on a single night

The naked-eye planets and the Moon at sunset and sunrise on a single night, starting with sunset on the right on July 27, 2022. The night ends on the left with sunrise on the 28th. Notice that all the naked-eye planets except Mercury are in the morning sky now. Click on the image to enlarge it. Created using my LookingUp program.
