12/11/2019 – Ephemeris – Where are the naked-eye planets now

December 11, 2019 Leave a comment

Ephemeris for Wednesday, December 11th. Today the Sun will be up for 8 hours and 52 minutes, setting at 5:02, and it will rise tomorrow at 8:10. The Moon, 1 day before full, will set at 8:28 tomorrow morning.

Let’s look at the naked-eye planets for this week. Venus will be briefly visible low in the southwest before it sets at 7:06 p.m. Jupiter is lost in twilight. It will pass behind the Sun on the 27th and will enter the morning sky. Saturn, the ringed planet, will be in the southwestern sky in the evening, and will set at 7:13 p.m. Tonight Saturn will be about 2 degrees or 4 moon widths to the upper right of the much brighter Venus. Mars is in the morning sky and will rise in the east-southeast at 5:13 a.m. It’s not very bright because it’s 215 million (346 million km) miles away, but it’s getting slowly closer to the Earth. Mercury is now too close to the Sun to be seen in morning twilight.

The times given are for the Traverse City/Interlochen area of Michigan. They may be different for your location.

12/04/2019 – Ephemeris – Where are the naked-eye planets this week?

December 4, 2019 Comments off

Ephemeris for Wednesday, December 4th. Today the Sun will be up for 8 hours and 59 minutes, setting at 5:02, and it will rise tomorrow at 8:04. The Moon, at first quarter today, will set at 1:01 tomorrow morning.

Let’s look at the naked-eye planets for this week. Venus will be briefly visible low in the southwest before it sets at 6:54 p.m. Jupiter will be very difficult to spot below and right of Venus. It will set at 6:13 p.m. Saturn, the ringed planet, will be in the southwestern sky in the evening, and will set at 7:37 p.m. Mars is in the morning sky and will rise in the east-southeast at 5:16 a.m. It’s not very bright because it’s 219 million (353 million km) miles away, but it’s getting slowly closer to the Earth. Mercury can be spotted after it rises in the east at 6:25 a.m. This is pretty much the end of its morning visibility, as the planet is moving around and behind the Sun. These oscillations from one side to the other of the Sun take on average of 116 days.

The times given are for the Traverse City/Interlochen area of Michigan. They may be different for your location.
