Planets of the Month: January 2022

By Erich Karkoschka

Mercury is visible in the evening sky at dusk and is less than 4 degrees below Saturn from the 9th to the 16th. Around January 16th it switches to the morning sky (about two weeks after Venus) and visible around the 31st.

Venus is visible at early dusk until the 5th. It is larger than one arc-minute in diameter, the largest it can get, and less than two percent illuminated. A spectacular crescent in the telescope. Starting on the 11th, it is the morning “star” with altitudes quickly climbing. By the end of the month it is already well up at the start of dawn.

The Moon comes into the evening sky on the 3rd, when it is about as difficult to see as Mercury and just a little below Mercury. The next evening, the Moon joins Saturn and the following evening, it joins Jupiter.

Iris has a good opposition in Gemini and is brighter than magnitude 8.

Mars is low at dawn. It is close to Antares on the 1st but 20 degrees further east by the end of the month.

Jupiter is still higher than Saturn and keeps going once the other three planets have left the evening sky. By the 31st, it sets within an hour of the end of dusk.

Saturn also switches from evening to morning visibility, but much more slowly. It leave the evening sky on the 19th and will not be visible in the morning until March.

Uranus and Neptune are still higher than Jupiter in the evening sky. Uranus transits just after the end of twilight at 72 degrees altitude.

Comet Leonard could be the best comet of the year during the first week of January, maybe as bright as 3rd magnitude with a nice tail. It is almost stationary 20 degrees to the lower left of Saturn, quite low when dusk ends. Then, it will get even lower and will probably fade, ending its visibility.

Planets of the Month: December 2021

By Erich Karkoschka

Starting on the 22nd, Mercury joins the other three planets at dusk. First, it is below Venus. Then on the 29th to the left of Venus, and then further left and higher than Venus.

Venus is at its brightest during early December. On the 6th, the moon will be close to it. You may be able to find Venus well before sunset about 3 degrees above the moon. Later in December, it rapidly approaches the sun and thus gets low during dusk. By the end of the year, its diameter exceeds one arc-minute, the largest it can get. Its slim crescent is a beautiful sight in telescopes and also visible in binoculars.

From the 5th to the 8th, the lunar crescent passes the three bright planets at dusk. On the last morning of the year, it is close to Mars and Antares.

Mars is the lonely planet at dawn, but faint and low, fare below Spica.

Ceres is still 7th magnitude in Taurus, but fading. On the other hand, Iris is brightening at 8th magnitude in Cancer.

Jupiter is about 15 degrees higher then Saturn and still well positioned for telescopic observations.

Saturn is about 15 degrees above Venus and 15 degrees below Jupiter. It will become invisible in January.

Uranus and Neptune are high in the evening sky. Jupiter will be catching up with Neptune and pass it in April, invisible behind the Sun.

Comet Leonard is in the morning sky near the limit of naked eye visibility until it gets too close to the sun on the 12th. On the 3rd, it is close to globular cluster M3. On the 6th, it is 5 degrees to the left of Arcturus. On the 10th, it is 5 degrees to the left of Alpha Serpentis.

A Total solar eclipse occurs on the 4th, but is far away in Antarctica.
