Moon Near Heart of the Lion

   Sunday evening the 4.3-day old waxing crescent Moon will be about 4o from the star Regulus, the heart of Leo the Lion. Spread across the sky from west to east are three planets, Venus, Jupiter, and Saturn.

June Moon at Ascending Node

   Saturday June 16th the waxing crescent Moon will be crossing the plane of the ecliptic moving north relative to the ecliptic. This is known as the ascending node, one of two intersections the Moon’s orbital path has with the ecliptic. The ecliptic is actually the Earth’s orbit and the Moon’s orbit is inclined about 6o from the ecliptic. So there are two node intersections, the ascending and descending nodes.

   On Saturday evening June 16th the 3.5-day old waxing crescent Moon will be about 8o east (left) from the planet Venus and about 3o from the open star cluster, M-44 also, known as the ‘Beehive Cluster’.

   Does our Moon actually go around the Earth as many graphics show? From our perspective on the Earth the Moon appears to circle around the Earth. However, in reality, the Moon orbits the Sun together with the Earth*

Moon Passes the Twins and Venus

   Friday evening June 15th the 3.75-day young waxing crescent Moon will be to the left from the ‘Twin’ stars of Pollux and Castor. A little further east or higher above the Moon is the ‘hard-to-miss’ planet Venus.

   Over the next 24 hours the Moon will have orbited eastward and by the same time Saturday evening June 16th the waxing crescent Moon will be ‘above’ Venus, or further east than Venus is.

Young Crescent Moon in Conjunction with Mercury

   Thursday evening June 14th the thin 1.25-day young waxing crescent Moon will be about 2-3o from the innermost planet Mercury as the two are setting about an hour after sunset local time.
    As the graphic shows both will be low over the horizon before the sky is dark so this may be an interesting challenge to see either one or both. On the other hand further east, higher above the horizon, and very bright appearing is the other inner planet, Venus.

Venus and the Twins


   Over the next few evenings, June 7th to 10th, the inner planet Venus will pass the star Pollux, marking the head of one of the Gemini Twins. Pollux is on the left side as we view the ‘Twins’ face-on. This animated graphic is set for 10 pm CDT and shows the daily movement of Venus toward the east, combined with the daily motion of the stars toward the west as the Earth revolves around the Sun.


   The separation between Venus and Pollux will vary from about 4.5o to about 5.5o allowing at least these two to fit within a binocular field of view.

Venus and Moon Are In Conjunctions

   Monday evening May 21st the first quarter Moon and the inner planet Venus will each be in their own respective conjunctions. Venus is within 1o from the open star cluster, M-35, located near the foot of Castor, one of the Gemini Twins. Venus currently shines with an apparent magnitude of -3.96, and at that brightness will outshine the 5th magnitude of M-35.

    Nonetheless the two should be visible with binoculars, as this graphic simulates, as well as a couple of 3rd magnitude stars nearby.


   Further toward the east, and unmistakable is the first quarter Moon. During the night hours the Moon, as it orbits eastward, will pass within about 1.5o from the star Regulus in Leo the Lion. Since Regulus is very close to the ecliptic there is a good chance that the Moon and Regulus will have a regular repetitive pattern or cycle of conjunctions. As in the months that Regulus is above the horizon, which include the next two months, June 18th and July 15th.

May Moon at Ascending Node

   Sunday May 20th the waxing crescent Moon will be crossing the plane of the ecliptic moving north relative to the ecliptic. This is known as the ascending node, one of two intersections the Moon’s orbital path has with the ecliptic. The ecliptic is actually the Earth’s orbit and the Moon’s orbit is inclined about 6o from the ecliptic. So there are two node intersections, the ascending and descending nodes.

   On Sunday evening May 20th the 5.5-day old waxing crescent Moon will be just within the boundaries of Leo the Lion and about 14o west (right) from the ‘Heart’ of the Lion, the star Regulus.

   Does our Moon actually go around the Earth as many graphics show? From our perspective on the Earth the Moon appears to circle around the Earth. However, in reality, the Moon orbits the Sun together with the Earth*
