Moon – Saturn Conjunction

   Tuesday June 18th at around midnight local time the just past full Moon will be rising over the eastern horizon near the ringed planet Saturn. The two will be separated by about 0.5o and will fit nicely within the field of view of binoculars or the eyepiece of a telescope..

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 Ascending Node and in Conjunction with Mars

   Wednesday June 5th the 5-day old 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 the day of the node crossing the 2.70-day old waxing crescent Moon is over the southwestern horizon at sunset local time and is 4-5o from the planet Mars. Both will easily fit within the field of view of binoculars.

   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*

Waxing Crescent Moon – Mercury Conjunction

click on graphic to see it larger   Tuesday evening June 4th the thin 1.5-day old waxing crescent Moon will be over the north western horizon around sunset local time, and will be about 4-5o from the innermost planet Mercury. The planet Mars is also visible and is about 8-9o east (above to the left) from the Moon.

Waning Crescent Moon – Venus Conjunction

   Saturday morning June 1st watch for a very thin 27.5-day old waning crescent Moon to rise with the inner plane Venus. The Moon will be about 5o from Venus, and despite the Moon’s thin appearance its apparent magnitude of -9.0 will still outshine Venus apparent magnitude of -3.80. Nonetheless both should make a striking pair over the horizon before sunrise local time.
