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 – Regulus Conjunction

   Friday June 8th the 5.60-day old waxing crescent Moon will be within about 2o from Regulus, the star marking the heart of Leo the Lion. Both will be visible high over the southern horizon at sunset local time.

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*

Waxing Crescent Moon Near Beehive Cluster

   Thursday evening June 6th the 3.70-day old waxing crescent Moon will be within about 4o from the open star cluster M-44, or more commonly known as the “Beehive Cluster”. Despite the crescent Moon’s apparent magnitude of -10.0 it should be possible to still see the Beehive Cluster dimly ‘glowing’ with its 3.50 apparent magnitude in the field of view of binoculars.

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.
