Planets of the Month – December 2025

By Erich Karkoschka

Saturn is transiting around 7 pm, later this month at 6 pm, ideally suited for evening observations. Its rings open and brighten up by a factor of three this month, but remain as thin as a line. All moons orbit back and forth on the same line.

Neptune is 3 degrees east of Saturn. On February 15, it will be the minimum in 35 years, less than 1 degree.

Uranus is 4.5 degrees south of the Pleiades. This month is the closest distance during its 84 year orbit.

Jupiter rises at 8 pm, later at 7 pm. It is near Pollux. It is getting close to opposition.

Mercury is very easy to see around 6:15 to 6:30 am. It rises even before twilight starts.

The Moon is back in the evening sky on the Solstice, the 21st, as a thin crescent. The highest Full Moon in its 18-year nodal cycle occurs on New Year’s Day at 11 pm with an altitude of 86 degrees, not far from 90 degrees.

Solar Telescope Observing @ Saguaro NP – East

January 4 @ 1:00 pm 3:00 pm

The Sun is at its peak in the sunspot cycle so there is LOTS of activity on its surface.

This event is FREE and open to the public, no reservations required.  NPS admission fees apply.

The telescopes will be set up at the Bicycle Ramada next to, or at, the Visitors Center.
This event will most likely be canceled in the event of clouds/rain.
