October 5, 2022 Comments off

This is Ephemeris for Wednesday, October 5th. Today the Sun will be up for 11 hours and 30 minutes, setting at 7:15, and it will rise tomorrow at 7:46. The Moon, 3 days past first quarter, will set at 3:33 tomorrow morning.

Let’s search for the naked-eye planets for this week. The waxing gibbous Moon will be visible near Saturn tonight, with the ringed planet right and above our Moon.

One star in their direction may be visible and low on the horizon and in line tonight with Saturn and the Moon. It’s Fomalhaut, normally the loneliest star in the sky. Before seven tomorrow morning, the red planet Mars will be high in the south, above the winter constellation of Orion. At that hour, Mercury can also be spotted low in the

Telescopic views of Saturn Jupiter and Mars

Telescopic views of Saturn Jupiter and Mars (north up) as they would be seen in a small telescope, with the same magnification. The image doesn’t show it, but the white north polar cap will appear at the top or north limb of Mars. Saturn and Jupiter are shown at 9 pm, Mars at 6 am.
