Ephemeris: 09/06/2023 – Let’s find out where the naked-eye planets and comet Nishimura have wandered off to
This is Ephemeris for Wednesday, September 6th. Today the Sun will be up for 12 hours and 59 minutes, setting at 8:10, and it will rise tomorrow at 7:12. The Moon, at last quarter today, will rise at 11:40 this evening.
Let’s find out where the naked-eye planets have wandered off to. Three of those five planets are now visible but Mars and Mercury are too close to the Sun to be seen. Saturn is the sole evening planet visible. Jupiter and Venus are officially the only visible morning planets. Saturn can be spotted in the southeast in the evening. And it will still be visible throughout the morning hours morning until twilight starts. Saturn is in retrograde or westward motion against the stars of Aquarius. Jupiter will rise at 10:54pm. It is slowing its eastward motion and will become stationary tomorrow. Venus is our brilliant morning star. It will rise at 4:43 tomorrow morning. Comet Nishimura is left and a bit below Venus in the east-northeast.

Let’s find out where the naked-eye planets have wandered off to this week. Only two of these five planets are visible. Mars, Mercury and Venus are all too close to the Sun to be seen. Jupiter and Saturn are officially morning planets, although Saturn does rise in the evening shortly after sunset. It will become an evening planet on the 27th, when it will rise at sunset. It can be spotted in the southeastern part pf the sky in the evening. It will also be visible throughout the morning hours. Saturn is in retrograde or westward motion against the stars of Aquarius now. Jupiter, still moving slowly eastward against the stars of Aries the ram, also rises in the evening, but barely, rising just before midnight. It will be stationary, that is, it will stop its eastward motion against the stars, and will begin its retrograde or westward motion on September 7th.

It will pass between the Earth and the Sun on the 13th, and be visible before sunrise by the end of the month.

Ephemeris: 07/26/2023 – Let’s find out where the naked-eye planets have wandered off to this week
This is Bob Moler with Ephemeris for Wednesday, July 26th. Today the Sun will be up for 14 hours and 53 minutes, setting at 9:15, and it will rise tomorrow at 6:23. The Moon, 1 day past first quarter, will set at 1:08 tomorrow morning. | Let’s find out where the naked-eye planets have wandered off to this week. Venus is our hard to find Evening Star, seen very low in the west in evening twilight by 9:45 pm. It will set at 10:11 pm, Mercury might be spotted to Venus’ right and a bit above. The red planet Mars is pretty much lost in the evening twilight, above and left of Venus. Saturn will rise at 10:38 pm. And by 5:30 am, or a bit less than an hour before sunrise tomorrow, it will appear in the south-southwest, the brightest “star” in that direction. Its above the bright star Fomalhaut, normally the loneliest bright star in the sky. Jupiter will be in the east-southeast at that hour. Jupiter is the brightest star-like object in the morning sky now, near some of the bright stars of a winter’s evening.

Ephemeris: 07/21/2023 – Antares just looks weird
This is Ephemeris for Friday, July 21st. Today the Sun will be up for 15 hours and 3 minutes, setting at 9:20, and it will rise tomorrow at 6:18. The Moon, halfway from new to first quarter, will set at 11:34 this evening.
We’ve had our Fourth of July fireworks over two weeks ago, but there’s one star still celebrating as a sparkler. That’s Antares in Scorpius the scorpion low in the south tonight. We in Michigan always see Antares low in the south. It’s a bright red giant star which twinkles mightily, and since it’s low in the sky, it spits and sputters all kinds of colors due to our atmosphere’s turbulence, and the fact that we’re looking through so much of it at Antares. At it’s highest, due south, we are seeing it though 3 times more atmosphere than we would be if it was overhead. The more magnification one uses with binoculars or a telescope, the greater the sparkler effect. It is even called in sometimes as a UFO.

Addendum

The name of the star Antares means “Rival of Mars”. “Ant” meaning anti, “Ares”, the Greek equivalent to the Roman god Mars. The reason is their similar reddish color. Antares is red because it is a cool star, a red giant. Mars is red due to its red dust, colored by iron rust. The planet passes Antares about every 23 1/2 months. Mars will next pass Antares on December 8th, 2023. However, the event will not be visible, because both the star and the planet will be too close to the Sun in the morning sky then. Their next meeting, or conjunction, after that, on November 17th, 2025 will be in the evening sky, but still too close to the Sun to be spotted. The conjunction after that will be in the evening sky, again rather close to the Sun, on October 28, 2027. For these three encounters, Mars will be north or above Antares, and dimmer than the star.

It will set at 10:31 pm, and by four minutes earlier each night. The red planet Mars is now pretty much lost in the evening twilight. We’ll see it in the morning sky in a few months. Venus too will soon leave the evening sky. Saturn will rise shortly after 11 pm. And by 5:15 am, or an hour before sunrise, it will appear in the south-southwest, the brightest “star” in that direction. It’s above the bright star Fomalhaut, normally the loneliest bright star in the sky. Jupiter will be in the east-southeast at that hour.
