10/28/2020 – Ephemeris – Let’s look for the naked-eye planets for this week
This is Ephemeris for Wednesday, October 28th. Today the Sun will be up for 10 hours and 20 minutes, setting at 6:36, and it will rise tomorrow at 8:17. The Moon, 3 days before full, will set at 6:05 tomorrow morning.
Let’s look for the naked-eye planets for this week. Jupiter and Saturn are both low in the south-southwestern sky at 8 pm. Jupiter is the very bright one. Left and a bit above it will be the somewhat dimmer Saturn. They are closing slowly, so they will cross paths on December 21st and be in the same telescope field that evening. Jupiter will set first tonight at 11:08 with Saturn following at 11:37. Off in the east-southeast at that hour will be Mars. Since the it was closest 22 days ago its distance has increased to 42.0 million miles (67.6 million km) away. Brilliant Venus will rise at 5:12 am in the east as it retreats slowly toward the Sun. We’ll have a big jump backwards in rise and set times next week when standard time returns.
The event times given are for the Traverse City/Interlochen area of Michigan. They may be different for your location.
