Planets of the Month – January 2024

By Erich Karkoschka

Saturn is well visible during the early evening. It sets around 8 pm. Soon it will be too close to the Sun. When it reappears in the Spring, Saturn’s rings will only be half as open as now.

Jupiter transits during dusk. It is very high and good for telescopic observations. On the 20th, Ganymede is transiting the disk after 10 pm, visible as a dark spot.

Uranus is high in the evening sky east of Jupiter.

Neptune is west of Jupiter.

Brilliant Venus is best observed between 5 and 6 am, just before down starts.

Mercury joins Venus, visible until the end of the month. It is to the lower left of Venus around 6-7 am. There is no other star at similar brightness in this area of the sky. If you see one, it is Mercury.

Mars is within half a degree of Mercury on the 27th. Since it is a magnitude fainter then Mercury, it may require very clear air to make it out naked eye. Binoculars will easily show this close pair.
