08/12/2020 – Ephemeris – Let’s look at a the naked-eye planets for this week

August 12, 2020 Comments off

This is Ephemeris for Wednesday, August 12th. Today the Sun will be up for 14 hours and 10 minutes, setting at 8:52, and it will rise tomorrow at 6:43. The Moon, 1 day past last quarter, will rise at 1:16 tomorrow morning.

Let’s look at a the naked-eye planets for this week. Jupiter and Saturn are both low in the south-southeastern sky at 10 pm. Jupiter is the very bright one. To the left of it will be Saturn. They now seem to be separating a bit due to the Earth’s motion now, but they will cross paths in December. Both planets will be up most of the night with Jupiter setting first at 4:02 tomorrow morning and Saturn following at 4:44 am. The next planet visible will be Mars which will rise at 11:22 pm. Its now down to 54.3 million miles (87.5 million kilometers) away, as the Earth slowly overtakes it at the rate of about 3.4 million miles (5.4 million kilometers) a week. Brilliant Venus will rise at 3:09 am in the east-northeast and is as far west from the Sun as it can get today.

The event times given are for the Traverse City/Interlochen area of Michigan. They may be different for your location.
