This is Bob Moler with Ephemeris for Wednesday, October 21st. Today the Sun will be up for 10 hours and 40 minutes, setting at 6:47, and it will rise tomorrow at 8:08. The Moon, 2 days before first quarter, will set at 10:39 this evening.
Let’s look for the naked-eye planets for this week. Jupiter and Saturn are both low in the south-southwestern sky at 9 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 11:28 with Saturn following at midnight. Off in the east-southeast at 9 pm will be Mars. Since the it was closest 15 days ago its distance is slowly increasing to 40.1 million miles (64.6 million km) away. Brilliant Venus will rise at 4:55 am in the east as it retreats slowly toward the Sun. It’s brilliant and looks like a tiny featureless gibbous moon in telescopes.
The event times given are for the Traverse City/Interlochen area of Michigan. They may be different for your location.
