Ephemeris: 07/02/2026 – Finding Ophiuchus, the celestial snake handler

July 2, 2026 Leave a comment

This is Ephemeris for Thursday, July 2nd. Today the Sun will be up for 15 hours and 30 minutes, setting at 9:31, and it will rise tomorrow at 6:02. The Moon, 3 days past full, will rise at 11:26 this evening.

The red star Antares shines in the south at 11 p.m. In the constellation of Scorpius. In the area of sky above and a little to the left lies a large constellation of faint stars called Ophiuchus, the serpent bearer. The constellation shape is like a large bell, which reminds me of the head, shoulders and arms of a fellow that’s holding the large snake across his body, hip high. The serpent he’s holding is Serpens, the only two-part constellation in the heavens. The head rises to Ophiuchus’ right, toward Hercules, and the tail extends up to the left, toward Aquila the eagle. In Greek myth, Ophiuchus represents the great physician Aesculapius, educated by the god Apollo, and the centaur Chiron, who is found in the stars as Sagittarius, now rising below and left of him.

Ephemeris: 07/01/2026 – Taking our weekly look at the whereabouts of the naked-eye planets

July 1, 2026 Leave a comment

This is Ephemeris for Wednesday, July 1st. Today the Sun will be up for 15 hours and 30 minutes, setting at 9:32, and it will rise tomorrow at 6:01. The Moon, 2 days past full, will rise at 11:01 this evening.

Let’s take our weekly look at the whereabouts of the naked-eye planets. By 10:30 PM tonight, nearly an hour after sunset, Venus is easily seen in the western sky, with Jupiter barely above the horizon, and may not be visible. A telescope will show a very tiny gibbous disc of Venus, because it is still pretty much beyond the Sun, 97 million miles (156 million kilometers) away from us. Over the next nearly 4 months it will be moving closer to us and becoming much larger. In the morning, Saturn will rise at 1:41 AM, followed by dimmer Mars nearly 2 hours later. The Earth is now chasing down Mars, and later this year the launch window will open to send spacecraft to the Red Planet. Mars will be next closest to the Earth in February next year.

Telescopic Venus at 10:30 PM tonight, July 1, 2026, and Saturn at 5 AM on the 2nd (north up), as they would be seen in a small telescope with the same magnification. Venus’ apparent diameter will be 16.1″, and be 68.4% illuminated. Saturn will be 17.5″ in diameter, and its rings extend to 40.9″ and are tilted 9.0º to our view. Mars, not shown, will appear 4.5″ in diameter. The (”) symbol means seconds of arc, or 1/3600th of a degree. Created using Cartes du Ciel (Sky Charts), LibreOffice Draw and GIMP.
