THE PLANETS in NOVEMBER 2021

VENUS is a brilliant object in the evening sky, on the 1st setting just after 12 midnight, NZDT. During November the fraction of the planet illuminated by the Sun, as seen from Earth decreases, from 48% to 29%, but even so it becomes if anything more brilliant.

MERCURY, in the morning sky, rises only half an hour before the Sun on the 1st. It reaches superior conjunction at the far side of the Sun on the 29th, so is unobservable all month.

MARS is even closer to the Sun than Mercury at first. The two planets are only 1° apart on the 10th, a conjunction which will be extremely difficult to see. By the end of the month Mars will be a little further from the Sun, but still a difficult morning object.

JUPITER and SATURN are both easily visible in the evening sky, setting after midnight.

The moon passes Saturn on the 10th, when they will be 5° apart before midnight. The following evening the moon at first quarter, will be rather further from Jupiter.

URANUS, NEPTUNE and PLUTO continue to move into the evening sky with first Neptune and then, later in the month, Uranus rising well before sunset.

POSSIBLE BINOCULAR ASTEROIDS in NOVEMBER

                Mag  Cons  transit    Mag  Cons  transit
 (1) Ceres      7.7   Tau   3.15am    7.1   Tau  12.55am
 (2) Pallas     9.5   Aqr   9.24pm    9.8   Aqr   7.39pm

 (7) Iris       9.1   Gem   6.30am    8.6   Cnc   4.52am

CERES starts November close to Aldebaran. The asteroid is closest to the star on the 3rd when the two are only 7 arc-minutes apart with Ceres to the south of the star. They will then rise about 10pm NZDT. Over the rest of the month Ceres will move through the Hyades cluster and beyond. It rises just before 7pm by the 30th

PALLAS is an evening object in Aquarius. It is stationary at the start of the month. The asteroid subsequently moves to the east rising just before 1pm on the 30th.

VESTA is close to the Sun all month with a conjunction on the 29th when they are less than a degree apart.

IRIS is a morning object starting November in Gemini but moving on into Cancer on the 4th. Iris is stationary on the 30th, at the start of its retrograde movement. It will then rise at 11.50 pm.
