07/14/2021 – Ephemeris – It’s Wednesday, do you know where your naked-eye planets are?

July 14, 2021 Comments off

This is Bob Moler with Ephemeris for Wednesday, July 14th. Today the Sun will be up for 15 hours and 15 minutes, setting at 9:26, and it will rise tomorrow at 6:11. The Moon, 3 days before first quarter, will set at 12:23 tomorrow morning.

Let’s search for the naked-eye planets for this week. Venus can be spotted low in the west-northwest twilight by 10 pm or a little after. It will set at 10:57 pm. Venus will be spending the rest of summer low in the western sky, and not be as conspicuous as it usually is as the Evening Star. Mars’ visibility is a real problem. It will be to the right and a bit below Venus in the evening, and will set at 10:52 pm. It’s much dimmer than Venus, so I doubt anyone at our northern latitude could spot it. Saturn and Jupiter, are seen starting very late in the evening and best in the morning sky. Saturn will rise at 10:18 pm. Brighter Jupiter will rise at 11:09 pm, both in the east-southeast. By 5 am, these two planets will be in the southern sky in the morning twilight.

The astronomical event times given are for the Traverse City/Interlochen area of Michigan (EDT, UT – 4 hr). They may be different for your location.
