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

July 1, 2026 bobmoler 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.

The astronomical event times given in this blog are for the Traverse City/Interlochen area of Michigan (Lat 44.7° N, Long 85.7° W; EDT, UT – 4 hours) unless stated otherwise. Times will be different for other locations.

Ephemeris: 06/24/2026 – Where are the naked-eye planets this week?

June 24, 2026 bobmoler Comments off

This is Ephemeris for Wednesday, June 24th. Today the Sun will be up for 15 hours and 34 minutes, setting at 9:32, and it will rise tomorrow at 5:58. The Moon, 3 days past first quarter, will set at 2:36 tomorrow morning.

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 and Jupiter are seen in the western sky, with Jupiter below and right of the brighter Venus. Mercury, though being just above the horizon at that time, is completely overcome by the twilight. A telescope will show a very tiny gibbous disc of Venus, because it is still pretty much beyond the Sun, 102 million miles (164 million kilometers) away from us. Over the next 4 months it will be moving closer to us and becoming much larger. In the morning, Saturn will rise at 1:52 AM, followed by dimmer Mars nearly 2 hours later. The Earth is now chasing down Mars, and soon the launch window will open to send spacecraft to the Red Planet.

By 10:15 PM tonight, nearly an hour after sunset, Venus and Jupiter, and even Mercury may be seen in the western sky, with Jupiter below and right of the brighter Venus, and Mercury below and right of Jupiter. Jupiter appears to be chasing Mercury back toward the sun. But Mercury is getting dimmer, and will soon be lost in the twilight glow. A telescope will show a very tiny disc on Venus, because it is still pretty much beyond the Sun, 106 million miles (171 mil km) away from us. Over the next 4 months it will be moving closer to us and becoming much larger. In the morning, Saturn will rise at 2:37 AM, followed by dimmer Mars an hour and a half later.

This is Ephemeris for Wednesday, May 6th. Today the Sun will be up for 14 hours and 28 minutes, setting at 8:53, and it will rise tomorrow at 6:24. The Moon, 3 days before last quarter, will rise at 1:55 tomorrow morning.

Let’s take our weekly look at the whereabouts of the naked-eye planets. By 9:30 PM tonight or about 35 minutes or so after sunset, Venus may be seen very low in the West. A telescope will show a very tiny disc on Venus, because it is still pretty much beyond the Sun, 131 million miles (211 million kilometers) away from us. Over the next 5½ months it will be moving closer to us and becoming much larger. Jupiter is the brilliant star-like object in the western before 10 PM. It is above and left of the brighter Venus. Venus will set at 11:26 PM, while Jupiter will hold out until 1:40 AM. Saturn may be glimpsed starting about next Monday just after it rises in the east around 5:15 AM, and before morning twilight overwhelms it sometime later.

Addendum

Jupiter, and Venus with fading winter stars at 10 PM tonight, May 6, 2026. Jupiter and Venus are appearing to approach each other. They will be in conjunction on the evening of June 8th. Created using Stellarium.

The Moon, 2 days before last quarter, as seen at 5 AM tomorrow morning, May 7, 2026. A view visible in small telescopes showing an image with and without selected features labeled. Created using Stellarium, LibreOffice Draw, and GIMP.

Telescopic Jupiter and Venus (north up) as they would be seen in a small telescope with the same magnification. Venus will be visible for a short time near the western horizon, while Jupiter will be visible until after midnight. Venus’ apparent diameter will be 11.9″, and be 86.5% illuminated. It’s on the far side of the Sun. Jupiter will be 35.0″ in diameter, with its moons shown here for 10 PM, tonight May 6, 2026. Callisto will begin to transit the face of Jupiter at 10:31 PM.. Europa will pass behind the planet (an occultation) beginning at 11:36 PM. The moons can shift noticably over an hour, especially Io and Europa. The (”) symbol means seconds of arc, or 1/3600th of a degree. Created using Cartes du Ciel (Sky Charts), LibreOffice Draw and GIMP.

A low precision ephemeris of the Sun Moon and naked eye planet positions for today and tomorrow, May 6 and 7th, 2026. — This is *a low precision ephemeris of the Sun Moon and naked eye planet positions for today and tomorrow, May 6 and 7th, 2026.* Some of the columns are self-explanatory, others are not. The transit column is the time that the body crosses the meridian and is due south. Elong, for elongation, is the angle between the Sun and that body. RA is right ascension, which is the object’s east-west position on the celestial sphere in hours and minutes. Dec is declination which is the north-south position of the object on the celestial sphere in degrees and minutes. R is the distance of that object from the Sun in astronomical units. An astronomical unit is about 93 million miles or 150 million kilometers. And Delta is the distance of that object from the Earth, also in astronomical units. I omit the ‘m’ in am and pm for compactness. The data was generated using my LookingUp for DOS app and displayed as a table by my Ephemeris Helper app.

Ephemeris: 04/29/2026 – Taking our weekly look at the whereabouts of the naked-eye planets

April 29, 2026 bobmoler Comments off

This is Ephemeris for Wednesday, April 29th. Today the Sun will be up for 14 hours and 9 minutes, setting at 8:45, and it will rise tomorrow at 6:34. The Moon, 2 days before full, will set at 5:42 tomorrow morning.

Let’s take our weekly look at the whereabouts of the naked-eye planets. By 9:30 PM tonight or about 45 minutes or so after sunset, Venus may be seen very low in the West. A telescope will show a very tiny disc on Venus, because it is still pretty much beyond the Sun, 136 million miles (217 million kilometers) away from us. Over the next 6 months it will be moving closer to us and becoming much larger. Jupiter is the brilliant star-like object in the western before 10 PM. It is above and left of the brighter Venus. Venus will set at 11:11 PM, while Jupiter will hold out until 2:12 AM. Meanwhile, Mercury, Mars and Saturn are breaking up just west of the Sun, but are still overwhelmed by bright morning twilight.
