The Planets in November 2017

Two planets are visible in the evening sky, Mercury and Saturn. Mercury sets over two hours before Saturn on the 1st, but some 15 minutes later than Saturn on the 30th.

The other three naked eye planets are morning objects. Venus rises about 30 minutes before the Sun all month, Mars increases its distance from the Sun so rising 2 hours before the Sun at the end of November. Jupiter will be too close to the Sun to see at the beginning of the month, but should become briefly visible very low about 50 minutes before sunrise by the end of the month

Evening Sky

Mercury is an early evening object but will be very low when the sky is dark enough to see the planet. On the 1st , 45 minutes after sunset, the planet at magnitude -0.4 will be 5°above the horizon. At the end of November, 45 minutes after sunset, Mercury will be a little higher, 8.5° and slightly fainter, magnitude -0.1.

On the last few days of November Mercury will be quite close to Saturn, the latter being some 3° to the lower right of Mercury. Earlier in the month on the evening of the 13th the planet will be just over 2°to the right of Antares. Earlier still in November the planet will be less than 2 arc minutes from the magnitude star delta Scorpii on the morning of November 8, in daylight for NZ.

Saturn is an early evening object during November. It sets just over 3 and a half hours after the Sun on the first, an interval decreasing to 86 minutes by the 30th. The planet stars November in Ophiuchus but moves on into Sagittarius mid month.

The crescent moon will be some 4.5° to the right of Saturn as seen soon after sunset on the 21st.

Morning Sky

Venus is a nominal morning object, but it rises only about half an hour before the Sun all month. This will make it a difficult object despite its brightness, magnitude -3.9. Look for the planet low to the east shortly before sunrise. During the month Venus passes Jupiter, the two are less than half a degree apart on the morning of November 14. Shortly before sunrise the two will be less than 4° up and a little to the south of east.

Mars rises 75 minutes before the Sun on the 1st and 2 hours before it on the 30th, so is better placed in the morning sky than is Venus. But it is 5 magnitudes fainter. Mars is in Virgo and at the end of the month will be only 3° from Spica, at magnitude 1.1 the brightest star in the constellation. The crescent moon will be some 5° to the left of Mars on the morning of the 15th.

Jupiter is the third of the morning planets. It was at conjunction with the Sun at the end of October, so will be too close to the Sun to see during the first part of November. By the end of the month it will rise 80 minutes before the Sun. 40 minutes before sunrise on the morning of the 30th, Jupiter will be about 6.5° up and a little to the south of east. The planet starts the month in Virgo but crosses into Libra mid month.

Outer Planets

Uranus is in Pisces during November. Having been at opposition during October, it will be well paced in the evening sky once it is dark. The planet rises 80 minutes before sunset on the 1st increasing to almost 4 hours earlier on the 30th. The almost full moon is a few degrees from Uranus on the 3rd.

Neptune rises some three and three-quarter hours before Uranus, so is also a well placed evening object. By the end of November it sets about 2am. The planet is in Aquarius at magnitude 7.9. The moon close to first quarter is about 1.5° from Neptune on the 27th.

Pluto, magnitude 14.4, remains in Sagittarius. Like Uranus and Neptune, it is an evening object, although it will set near 11.30 pm by the end of the month. During November, Pluto will be slowly moving away from the 2.9 magnitude star pi Sgr. By the 30th they will be a little over 1.5° apart.

Minor Planets

(1) Ceres is a morning object in Cancer. It starts November in Cancer at magnitude 8.5, crosses into Leo on the 21st and ends the month at magnitude 8.1

(2) Pallas is in Fornax during November. It is at its brightest, magnitude 8.2 in the first part of the month, being at opposition on the 8th. When it will by some 254 million km, 1.70 AU, from the Earth. After opposition it will slowly start to fade but still be magnitude 8.4 at the end of November.

(4) Vesta is in Virgo during most of November. It will be a low morning 8th magnitude object. On the 1st it will be 3.5° from Venus but the latter will soon move away from the asteroid. Vesta crosses into Libra on the 29th, by then it will be less than 6° from Jupiter.

(7) Iris, following its opposition at the end of October, will dim a little from magnitude 6.9 to 7.7, the reverse of October. Even so, it remains the brightest asteroid this month. Iris's path in Aries takes it away from Hamal and towards beta Ari, magnitude 2.6. At their closest the two are just over a degree apart on the 8th, with Iris to the right of beta as seen about 10 pm. The asteroid's apparent movement is mostly to the south and it is stationary at the end of the month.

(8) Flora brightens from magnitude 9.7 to 9.1 during November It is a morning object rising about 1 am and spends the month in Gemini. It starts November about 1.5° from eta Gem magnitude 3.6. The two are closest on the morning of the 8th with Flora 0.25° north of eta.

(20) Massalia, like Flora brightens from magnitude 9.8 to 9.0 during November. It also starts the month in Gemini, but further west than Iris, near the border with Orion which Massalia crosses into on the 27th. Massalia starts November about 1.8° to the west of the red star Praepes, eta gem
