07/20/2022 – Ephemeris – Let’s search for the naked-eye planets for this week

July 20, 2022

This is Ephemeris for Wednesday, July 20th. Today the Sun will be up for 15 hours and 5 minutes, setting at 9:21, and it will rise tomorrow at 6:17. The Moon, at last quarter today, will rise at 1:13 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 5:15 am tomorrow, the planets will be spread out from brilliant Venus low in the east-northeast to Saturn higher in the south-southwest. Mars will be a lot higher than Venus in the east-southeast. The waning crescent Moon will be just right of Mars. Jupiter is farther to the right in the southeast. Mars is dimmer than Jupiter, but is slowly getting brighter as the Earth creeps up on it. Saturn ends the line of planets lower than Jupiter in the south-southwest. Tonight, Saturn will rise about 10:30 pm, though it won’t be an official evening planet until it rises before sunset, which won’t happen until mid-August.

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.


The morning planets and the Moon at 5:15 am tomorrow morning, July 21, 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.

    HI Bob,
    Keep up the great work!
    Thanks for all the info.

    But it’s the waning/half/ Moon, not the waning /crescent /Moon.
    That’s next week.
