Moon in Conjunction with Jupiter

   Over the next two evenings, Thursday August 16th, the waxing crescent Moon, and Friday the 17th, the first quarter Moon will pass within about 7-8o from the outer planet Jupiter. Jupiter with a -2.0 apparent magnitude, is about 0.5o from the 2.7 apparent magnitude star Zubenelgenubi in Libra the Scales.

   Joining the Moon and Jupiter are the planets Venus, Saturn, Mars, and Dwarf Planet Ceres.

Let the Moon Lead the Way


   Over the next 10 days, from August 13th to the 23rd, the Moon will move eastward, as it always does, following the ecliptic and interacting with planets and stars near the ecliptic.

Waxing Crescent Moon Near Venus

   Monday evening August 13th the thin 2.5-day young waxing crescent Moon will be about 10o from the inner planet Venus, and about 8o from the Dwarf Planet Ceres. However at 8th magnitude Ceres will be not be naked-eye visible, but Venus at a -4.6 apparent magnitude will be hard to miss!
   And spread out from west to east are the planets Jupiter, Saturn, and Mars.

August Perigee Moon at Ascending Node, and a Partial Solar Eclipse

   Friday August 10th the 28.5 day old waning 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.

   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*

Read this very informative article about the Earth-Moon system and their orbital motions, written by Joe Hanson. “Do We Orbit the Moon?”

Perigee Moon
   Our Moon reaches perigee, (closest distance to Earth), for this orbit on Friday August 10th. At that time the Moon will be at a distance of 28.07 Earth diameters (358,100 km or 222,513 miles) from the Earth. The Moon will also be 28.5 days old, and only 15.8 hours from new Moon Phase.
    When the time of perigee is close to a node crossing there will be either a lunar or solar eclipse. In this case less then 24 hours after the node crossing there will be a partial solar eclipse. This solar eclipse is only visible from Arctic, Greenland and parts of Asia.

Planet-A-Palooza plus the Moon

   This is one of those ‘best of times’ with regard to planet viewing. All of the visible planets are above the horizon although Mercury sets just before Mars rises. Times like this make it easy to visualize the ecliptic and its relationship with the planets. And our Moon, as it waxes toward full phase over the next several days, will pass by several planets and dwarf planets.

Moon in Conjunction with Venus


   Sunday evening July 15th the 3-day young waxing crescent Moon will be 2o from Venus, and 5o from the star Regulus in Leo the Lion. Further to the east are the planets Jupiter, Saturn, and Mars.


   The three, Moon, Venus, and Regulus, all fit comfortably within a binocular field of view.

Waning Crescent Moon in Close Conjunction with Aldebaran

   Tuesday July 10th in the hour or so before sunrise local time the very thin 26.5-day old waning crescent Moon will be within about 1o (width of 2 full Moons) from the reddish star Aldebaran in the open star cluster the Hyades. The Hyades are a v-shaped group of stars marking the face of Taurus the Bull. Reddish-colored Aldebaran represents an angry eye of the Bull.
   This conjunction is close enough so that a combination of a thin waning crescent Moon and the bright Aldebaran should make for a take a look with binoculars or the ‘naked-eye’.

   For those keeping track of Jupiter should be relieved to read that Jupiter’s retrograde motion has ended, and at least for the foreseeable future Jupiter has agreed to stick with the ‘program’ and resume it’s direct motion – eastward.
