June Moon at Descending Node

   Wednesday June 19th the Moon will be crossing the plane of the ecliptic moving south. This is known as the descending node, one of two intersections the Moon’s orbital path (dark green line) has with the ecliptic.

   On the day of the node crossing the 17.0-day old waning gibbous Moon will be over the southern horizon and will be about 13-14o to the east from the ringed planet Saturn.

Mars – Mercury Conjunction

   Monday evening June 17th the ‘Red Planet’ Mars and the innermost planet Mercury will be at a fairly close conjunction, separated by only about 0.5o. The two planets will be about 5-6o from Pollux, one of the stars of the Gemini Twins. Both planets will nicely fit within the field of view of binoculars or a wide field eyepiece on a telescope.

Moon on the Move

   Over the next several evenings (June 14th through the 16th) the Moon, as it waxes through its gibbous phase, will pass by the Dwarf Planet Ceres and the outer giant planet Jupiter. The Moon will be about 5-6o from Ceres as it passes from the west side to the east side of the Dwarf Planet. Then it will be about 5-6o from Jupiter as it moves from the west side to the east side of the Jupiter.

June Moon at Perigee

   Our Moon reaches perigee, (closest distance to Earth), for this orbit, on Monday May 13th. At that time the Moon will be at a distance of 28.89 Earth diameters, 228,977 miles (368,504 km) from the Earth.

   The 4.68-day old waxing crescent, Moon rises is over the southwestern horizon at sunset local time and sets around midnight. About 12o east from the Moon is the ‘Heart of the Lion’, the star Regulus in Leo the Lion. Between this time and and the same time tomorrow the Moon will have passed Regulus and be a few degrees away from the star, but on the east side.

   Does our Moon actually go around the Earth as this graphic shows? 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*
