11/11/2020 – Ephemeris – Let’s look for the naked-eye planets for this week

November 11, 2020

This is Ephemeris for Veteran’s Day, Wednesday, November 11th. Today the Sun will be up for 9 hours and 43 minutes, setting at 5:18, and it will rise tomorrow at 7:36. The Moon, 3 days past last quarter, will rise at 4:00 tomorrow morning.

Let’s look for the naked-eye planets for this week. Jupiter and Saturn are both low in the southwestern sky at 8 pm. Jupiter is the very bright one. Above and left it will be the somewhat dimmer Saturn. They are closing slowly, so they will cross paths on December 21st and be seen in the same telescope field that evening. Jupiter will set first tonight at 9:24 with Saturn following at 9:46. Off in the southeast at that hour will be Mars. Its distance is increasing to 47.7 million miles (76.9 million km) away. Mars will set at 4:35 tomorrow morning. Brilliant Venus will rise at 4:46 am in the east as it retreats slowly toward the Sun. Making a morning appearance this week is Mercury which will rise at 5:52 am in the east.

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

Evening planet finder animation

Evening planet finder animation for 8 pm November 11, 2020. The orange line is the ecliptic, the plane of the Earth’s orbit projected on the sky, and the path of the Sun through the year. All the planets can be found near that line. The zodiacal constellations from Taurus on the left to Capricornus on the right are shown without labels. Click on the image to enlarge. Created using Stellarium and GIMP.

It is the path of the Sun in the sky, The Moon is a crescent, and displayed at twice its apparent size. Over the next week Venus and Mercury will slide downward along the ecliptic in relation to the stars. Created using Stellarium.
