SUMMARY OF PLANETS IN 2022 MORNING SKY
Here is today’s planet forecast:
As the calendar turns over to today’s date, a bright congregation of stars is in the southern sky. The night’s brightest star, Sirius, is south at the midnight hour. The star rises in the east-southeast 2.5 hours after sundown, appears in the south at midnight, and sets in the west-southwest over two hours before sunup.
Mercury is retreating back into bright evening twilight and dimming as it moves toward its inferior conjunction – between Earth and the sun – on January 7th.
At forty-five minutes after sundown, find Mercury with a binocular 2.7° to the lower right of brilliant Venus that is about 5° up in the southwest. Speedy Mercury is dimming and tonight it is about the brightness of Saturn.
The Ringed Wonder is over 25° to the upper left of the Evening Star. Each evening, Saturn is lower in the southwest and Venus is higher. Venus passes Saturn on January 22nd. Each evening, watch Venus close in on Saturn.
As Mercury moves from the evening sky to a morning view, four bright planets are visible after sunset until early February.
This evening the moon, 60% illuminated, is over halfway up in the south-southeast sky and nearly 20° to the upper left of bright Jupiter.
Bright Mars is over one-third of the way up in the eastern sky and to the upper right of Aldebaran, Taurus’ brightest star.
Look for Betelgeuse near the horizon. It rises at sunset in a few evenings.
As the sky darkens further, look at Saturn through a binocular and note its position compared to the stars in eastern Capricornus. The planet forms a nice triangle with Nashira and Deneb Algedi. It is passing Nashira. This evening’s gap is 1.3°. Each clear evening watch Saturn move eastward compared to the starry backdrop. The Ringed Wonder passes Deneb Algedi on January 14th.
After the end of evening twilight, Mars is higher in the eastern sky. It is 8.3° to the upper left of Aldebaran. The Red Planet continues the illusion of retrograde until January 12th, passing the star again in the third conjunction of a triple conjunction series on January 30th. Look for the moon near Mars on January 3rd.
