JANUARY 2022 OBSERVING
Sun, Moon & Planets by Gary Seronik
To find out what's
visible in the sky from
your location, go to

Mercury, Venus, and Saturn Slip Away
A quartet of bright planets crowd the southwestern horizon at dusk.
SATURDAY, JANUARY 1
As the month gets underway, early risers
can watch Mars continue its journey
past Antares, in Scorpius. Antares is
a notable conjunction mate for two
reasons. First, it's the third brightest
star near the ecliptic (only Aldebaran
and Spica are marginally brighter), and
second, its color is a close match for the
Red Planet. On this particular morning,
however, Antares outshines its " rival " by
roughly half a magnitude. Can you see
the difference? And if you have a particularly
unobstructed view towards the
southeast, try to catch the razor-thin
(2%-illumined), crescent Moon lower
left of Mars and Antares. The warmhued
planet-star duo were actually
closest as December drew to a close, and
now Mars is gliding away from Antares
at a rate of about ½° per day. This rapid
eastward motion is one reason why the
planet remains stubbornly mired in
the haze near the dawn horizon. On
January 1st, Mars rises about two hours
ahead of the Sun, and by the 31st that
figure grows by only a couple of minutes.
Talk about slow progress!
MONDAY, JANUARY 3
Fresh from its dawn meetup with Mars
and Antares, the Moon returns to the
dusk sky where it forms a triangle very
low in the west-southwest with the two
innermost planets, Venus and Mercury.
Of the three, the Moon may prove to be
the toughest to spot, sitting about 12°
left of the brilliant Evening Star. If you
can't spot the thin lunar crescent this
evening, try again tomorrow when it'll
be fatter and much higher - the trio
still form a triangle, just a different one.
Mercury currently shines at magnitude
-0.7, and Venus gleams at magnitude
-4.2. However, the two planets are
moving in opposite directions - Mercury
is climbing higher, while Venus
is losing altitude as it heads toward its
January 8th conjunction with the Sun.
Don't worry - Venus won't be gone for
long. You should be able to spot it at
dawn starting on the morning of the
10th, when it begins an apparition that
will continue on through the end of
next summer. As interesting as triangles
are, more eye-catching is the luminous
line spanning 40° that includes Saturn
These scenes are drawn for near the middle of North America (latitude 40° north, longitude 90° west). European observers should move each
Moon symbol a quarter of the way toward the one for the previous date; in the Far East, move the Moon halfway. The blue 10° scale bar is about the
width of your fist at arm's length. For clarity, the Moon is shown three times its actual apparent size.
