is a low precision ephemeris of the Sun Moon and naked eye planet positions for today and tomorrow, June 11th and 12th, 2025. 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.https://bobmoler.blog/wp-content/uploads/2025/06/planets-and-the-moon-on-a-single-night-sunset-061125-to-sunrise-061225.pngPlanets and the Moon on a single night sunset 061125 to sunrise 061225 The naked-eye planets and the Moon at sunset and sunrise on a single night, starting with sunset on the right on June 11, 2025.

Mars is 5.2″ in diameter, too small to be shown here. My lower size limit is 10″. On the morning of the 12th, Saturn is 17.1″ in diameter, but its rings, being nearly edge on should show up brighter than seen here., and extend to 40.0″. They are tilted 3.4° from being edge on. Venus’ apparent diameter is 21.1″, and is 55.4% illuminated. The ” means seconds of arc, or 1/3600th of a degree.

Jupiter is shown for tonight, 10 PM, April 30, 2025. Its apparent diameter is 33.7″. Mars is 6.6″ in diameter, too small to be shown here. My lower size limit is 10″. Venus is shown in the morning of May 1st. Its apparent diameter is 40.6″, and is 23.3% iluminated. Saturn is 16.1" in diameter, but its rings, being nearly edge on and not illuminated, should not be visible. Planetary surface detail is more subtle than shown here.

Aphelion 2024This is a diagram of the true shape of the Earth’s orbit and position of the Sun showing aphelion and perihelion for the year 2024. The dates do vary by up to a couple of days each year as do the distances a little bit. The date difference is a bit more than the date change of the solstices and equinoxes year to year.

diagram of the measurement Aristarchus tried to make of the distance to the Sun. He got a distance to the Sun of 19.1 times the distance to the Moon, which correlates to an angle between the Moon and the Sun of 87°. The actual distance to the Sun is on the order, rounded up, of 400 times the Moon’s distance from the Earth. So this angle would be impossible to measure 89.85° (89° 51') for that interior angle instead of 87°.

Since the dawn arrives from the east, I think the word East may come from her name too. As far as I’ve been able to check the name of the feast of the Resurrection is related to the Passover in most other European countries.

The stars in the center cause the hydrogen gases to glow red. The hottest and brightest young stars give off ultraviolet light which causes the gases to fluoresce. Also, the stellar winds from these stars blows away gases from the center, so star formation stops. Leaving a beautiful rosette in the sky. Unfortunately it’s too faint to see with the telescope visually, however it is a wonderful target for astrophotographers. Click or tap on the image to enlarge it.

About 380,000 years later light was finally decoupled from matter. Before then the universe was opaque. Light could not travel very far before hitting another particle. At 380,000 years the universe became cool enough so that electrons and protons in this Big Bang soup could find each other and become atoms. This caused the universe to become transparent. At that point is where we see, with our radio telescopes, the cosmic microwave background radiation. After that there’s a period where stars are being formed. There’s not much light being emitted because the stars are not radiating brightly because the hydrogen fusion in their cores had not started. This period is called the dark ages and may have lasted up to 400 million years. The period of the first stars and galaxies is the area that James Webb Space Telescope was primarily built to investigate. It is only visible in the infrared. All this happened 9 billion years before the Earth was formed. It is evolution on a scale Darwin could not have imagined! Click or tap on the image to enlarge it.

animation of the precession of the equinoxes. The blue horizontal line is the celestial equator. The orange line is the ecliptic, the apparent annual path of the Sun against the stars. Where the two lines cross is the vernal equinox where the Sun is on the first day of spring, which on our calendar is trending to be March 20th. The slippage of the stars eastward (to the left) along the ecliptic is about the apparent width of the Sun or Moon, or half a degree, in 36 years. We’re looking at two different years 150 CE, the time of Ptolemy, and 2023, our time. To tell which is which, the one from our time has Saturn at the lower right. Jupiter happens to be in both of them, but it’s obviously been around lots of times between then and now.

span of the Milky Way across the summer sky as seen in the free Stellarium app. Specifically August 15th at 10 pm from Northern Michigan. The Milky Way has been set to its maximum brightness to show as much detail as possible. It really isn’t that bright. The horizon is only delineated by the compass points. The dark clouds of the Great Rift are also visible. The Milky Way, in Stellarium, is photo-realistic. The triangle of three bright stars above center is the Summer Triangle, Specifically, clockwise from the top star: Vega, Altair and Deneb. Large images can be truncated on the right.

The orange line is the ecliptic, which is the plane of the Earth's orbit. The sun appears on that line throughout the year. Notice that all the other planets are very close to that line. That is an artifact of the accretion disk from which the planets formed some 4 1/2 billion years ago. The planets still maintain the nearly same plane for their existence to this day.

The telescope can be set up on a table. The device on top is a red-dot finder. Looking through it will place a red dot on the object it's pointed to. It has no magnification of its own. The telescope eyepiece is a zoom type, so there is no need to remove it or change eyepieces to change magnification. The magnification range is from approximately 20 to 60 times (power). This is plenty for most objects in the sky, including the Moon, Jupiter and Saturn. Mars is a challenge for even the largest of amateur astronomer's telescopes. Even then it's best seen for a few months every 26 months.2023-01-06T04:22:37+00:00monthlyhttps://bobmoler.blog/2023/01/05/01-05-2023-ephemeris-im-sirius-about-this-being-the-brightest-nighttime-star/2023-01-04T21:43:19+00:00monthlyhttps://bobmoler.blog/2023/01/04/01-04-2023-ephemeris-lets-see-where-the-naked-eye-planets-have-wandered-off-to-this-first-week-of-2023/https://bobmoler.blog/wp-content/uploads/2023/01/planets-and-the-moon-on-a-single-night-sunset-010423-to-sunrise-010523.pngPlanets and the Moon on a single night sunset 010423 to sunrise 010523The naked-eye planets and the Moon at sunset and sunrise on a single night, starting with sunset on the right on January 4, 2023.

On the top line in yellow are the two eclipses of the Moon that occurred in the time period we’re interested in: 4 BCE and 1 BCE. One of then was the eclipse Josephus mentions that occurred shortly before the death of Herod the Great, who was alive to greet the Magi, who came to Jerusalem seeking the newborn King of the Jews. The second line highlights 3 and 2 BCE that the early Christian writers Irenaeus, Tertullian and Clement of Alexandria based Jesus' birth year to Roman events which can be pegged to the Roman Calendar which has a direct relationship to our own calendar. The next line contains hits based on the Crucifixion of Jesus at age 33, where the Last Supper was a Seder on the first day of Passover. The next line with C and P are two censuses of Augustus in our time period. The next to the last line shows the relation of the triple conjunction in 7 BCE with Jesus' birth and Herod's death. The bottom line related the two Venus-Jupiter conjunctions with Jesus' birth and Herod's death.2022-12-22T04:24:25+00:00monthlyhttps://bobmoler.blog/2022/12/21/12-21-2022-ephemeris-winter-starts-today-plus-our-weekly-look-at-the-bright-planets/https://bobmoler.blog/wp-content/uploads/2022/12/planets-and-the-moon-on-a-single-night-sunset-122122-to-sunrise-122222.pngPlanets and the Moon on a single night sunset 122122 to sunrise 122222The naked-eye planets and the Moon at sunset and sunrise on a single night, starting with sunset on the right on December 21, 2022.

It was a partial eclipse only visible in the predawn hours. This eclipse occurred one lunar month before Passover. Too little time for all the events Josephus describes. A better lunar eclipse occurred a bit less than three years later.2022-12-20T04:02:11+00:00monthlyhttps://bobmoler.blog/2022/12/19/12-19-2022-ephemeris-hunting-for-the-star-of-bethlehem-what-it-wasnt/https://bobmoler.blog/wp-content/uploads/2022/12/keplers-nova_stellarium.jpgKepler's Nova_StellariumHere is a Stellarium recreation of the sky the night of his discovery. It’s the southwestern sky near the end of evening twilight, October 9, 1604, the night Kepler discovered the supernova that bears his name. It got him to thinking, could a similar grouping of a nova and planets be the Star of Bethlehem? He knew of no nova being reported back then, though no one in the western world probably would have. That would be a change in the officially changeless heavens, so it couldn’t possibly have been a real heavenly object. And being the mathematical genius he was, (he did discover the Three Laws of Planetary Motion), found a very interesting conjunction of Jupiter and Saturn, with Mars piling on later, that occurred in 7 BCE.https://bobmoler.blog/wp-content/uploads/2022/12/keplers-nova_star-chart.jpgKepler's Nova_Star ChartKepler also discovered a supernova, the last one seen in the Milky Way. This is an old star chart that records Kepler's Star, a supernova, or super bright new star, he discovered on October 9, 1604. I colored it yellow and have an arrow pointed to it, in Ophiuchus’ right ankle.https://bobmoler.blog/wp-content/uploads/2022/12/johannes-kepler.jpgJohannes KeplerThe search for the Star really started with Johannes Kepler, who lived from 1571 to 1630. He was an astronomer, although he cast horoscopes for the odd prince or duke, which is how he made a living. His mother was even charged for being a witch, but nothing came of it. And after much trial and error discovered his Three Laws of Planetary Motion. His story is a fascinating one.2022-12-18T20:53:49+00:00monthlyhttps://bobmoler.blog/2022/12/16/12-16-2022-ephemeris-the-anishinaabe-constellation-of-winter-maker-announces-the-coming-of-winter/https://bobmoler.blog/wp-content/uploads/2022/12/winter-maker-lines_2100-121622.jpgWinter Maker lines_2100-121622The Anishinaabe constellation of the Winter Maker, whose arms will encompass the rest of the winter stars, once they rise later in the evening.2022-12-16T03:49:54+00:00monthlyhttps://bobmoler.blog/2022/12/15/12-15-2022-ephemeris-stories-of-the-pleiades-from-many-lands/2022-12-14T19:31:50+00:00monthlyhttps://bobmoler.blog/2022/12/14/12-14-2022-ephemeris-lets-see-where-the-naked-eye-planets-have-wandered-off-to-this-week-and-a-second-look-at-the-geminid-meteor-shower-near-its-peak/https://bobmoler.blog/wp-content/uploads/2022/12/planets-and-the-moon-on-a-single-night-sunset-121422-to-sunrise-121522.pngPlanets and the Moon on a single night sunset 121422 to sunrise 121522The naked-eye planets and the Moon at sunset and sunrise on a single night, starting with sunset on the right on December 14, 2022.

The sky is overlaid with the equatorial grid. The bright blue line that runs just above Orion's belt is the celestial equator. The declination lines match Earth's latitude lines are 10 degrees apart. The vertical blue lines are right ascension lines, like earthly longitude lines, and are 15 degrees apart. Each one represents one hour. The orange line is the ecliptic, the path of the Sun in the sky, also the plane of the Earth's orbit. The red line is the Moon's orbit, which is inclined by about 5 degrees to the ecliptic.

Assume we are looking down from the north, the motion of the Moon will be counterclockwise. The Moon will enter the shadow from the west or right, so the first "bite" of the shadow will be on the left side of the Moon. The penumbra is a gradually increasing shadow from the outer edge to the umbra, where the Sun is partially blocked by the Earth.https://bobmoler.blog/wp-content/uploads/2022/11/712px-geometry_of_a_lunar_eclipse.svg_.png712px-Geometry_of_a_Lunar_Eclipse.svg_https://bobmoler.blog/wp-content/uploads/2022/11/le2022nov08t.pngLE2022Nov08TCredit: NASA/GSFC, Fred Espenak.

The fine, folded line with tick marks is Saturn's path. The tick marks are at 10-day intervals. Saturn starts out in retrograde motion, heading westward or to the right. On October 23rd, it slows and stops that motion. It begins to head back eastward in its normal prograde motion to the left. Outer planets like Saturn, Jupiter, Mars and the rest exhibit retrograde motion when the Earth in effect passes them on the same side of the Sun. Click on the image to enlarge it slightly.

Dates in green are possible launch dates. I'm not sure but red dates are also forbidden because the Orion Capsule will experience more than 90 minutes in shadow at a time. It's powered by solar panels. Light green dates allow a long mission of 1 1/2 orbits of the Moon in the distant retrograde orbit (DRO). The dark green dates can only have 1/2 a DRO.

The asteroid pair developed a dust tail like a comet for a while. ATLAS is an acronym for a rather apocalyptic title “Asteroid Terrestrial-impact Last Alert System”. Developed by the University of Hawai’i and funded by NASA. It has two telescopes in Hawai’i, one in Chile, and one in South Africa.

Dimorphos does appear to be a rubble pile asteroid from its appearance and the amount of ejecta caused by the impact. The ejecta adds to the effect of the spacecraft’s kinetic energy by pushing away from the asteroid by Newton’s third law of motion.

It isn't really a wall, but a 7 degree slope. Once the Sun rises past seven degrees in that location of the Moon, it disappears. Near local sunset, a day after last quarter, the low sun in its sky shines more on it than the flat ground, so it shows up bright.

Thus, extended objects close to the horizon appear squashed a bit vertically.2022-09-10T15:41:52+00:00monthlyhttps://bobmoler.blog/2022/09/07/09-07-2022-ephemeris-lets-search-for-the-naked-eye-planets-for-this-week/https://bobmoler.blog/wp-content/uploads/2022/09/planets-and-the-moon-on-a-single-night-sunset-090722-to-sunrise-090822.pngPlanets and the Moon on a single night sunset 090722 to sunrise 090822The naked-eye planets and the Moon at sunset and sunrise on a single night, starting with sunset on the right on September 7, 2022.

M13 is almost bright enough to be spotted with the naked eye. It is easily visible in binoculars as a tiny fuzzy spot. It takes a telescope with an aperture of 6-8" or 150 - 200 mm to begin to see some individual stars. M92 is dimmer and harder to resolve.

The yellow line that appears is the ecliptic, the path of the Sun in the sky. The path of the Moon is tilted by about 5 degrees to that path. The paths cross at points called nodes. The nodes move slowly westward in an 18.6-year cycle called the regression of the nodes. Occultations of Regulus by the Moon occur during two periods in that cycle. The next period where occultations of Regulus will occur are monthly, from July 2025 to January 2027.
