June Moon at Ascending Node

   Thursday June 27th 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 June 27th the 4-day old waxing crescent Moon will be with the constellation Leo the Lion, and the Moon will be located less than 1o from the heart of the Lion, the star Regulus. This should make for a great view with binoculars or through the eyepiece of a telescope.
   Just above the western horizon, possibly lost in the Sun’s glare, are two more planets – Mars and Mercury about 1o apart.

   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*

Solar Eclipse of August 21


   I too have written some information about the solar eclipse, aka “The Great American Eclipse”, of August 21st. It is my attempt to compare two different views of the eclipse. One will be from within the path of totality where I will be, and the other in my hometown of Lee’s Summit Missouri just south of the path of totality by a few miles. As a result residents in Lee’s Summit, unless they drive north, will only see a partial eclipse with 99.986% of the Sun covered.

Moon Passes Regulus


   Tuesday and Wednesday evenings May 30th and 31st the waxing gibbous Moon will be passing the heart of Leo the Lion, the star Regulus.

May Moon At Perigee


   The Moon reaches perigee, (minimum distance from Earth), this month on Friday May 26th. At that time the Moon will more or less be at a distance of 28.0 Earth diameters (357,207 km or 221,958 miles) from the Earth.

   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*


   On the day of the perigee Moon the 1.25-day young thin waxing crescent Moon is above the western horizon at sunset local time and is near the planet Mars.

   On the day of the perigee Moon the 1.5-day young thin waxing crescent Moon is above the western horizon at sunset local time and is near Dwarf Planet Ceres and the Pleiades open star cluster.
