June Moon at Perigee

Our Moon reaches perigee, (closest distance from Earth), for this orbit on Friday June 23rd. At that time the Moon will be at a distance of 28.06 Earth diameters (357,937 km or 222,412 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 28-day old very thin waning crescent Moon is above the eastern horizon about 30 minutes to an hour before the Sun rises. This perigee Moon is less than 16 hours before it reaches new Moon phase. The Dwarf Planet Ceres will not be visible but it is where the graphic indicates it to be.

Venus – Crescent Moon Conjunction


   Tuesday morning June 20th the 25-day old waning crescent Moon will be about 6o from the inner planet Venus. At -4.6 apparent magnitude Venus contrasts well with the Moon’s -11 apparent magnitude.

Waxing Crescent Moon Near the Beehive Open Star Cluster


   Monday evening May 29th the 5-day old waxing crescent Moon will be within 3-4o from the open star cluster M-44, or as it probably more known as the “Beehive Cluster”, or from Latin, Praesepe, meaning “manger”.
   Both of which fit easily within the field of view of binoculars.

   This open star cluster, as a group, has a 3rd-4th apparent magnitude and to the naked eye appears as a fuzzy patch of light in Cancer the Crab. M-44 is near the 4th magnitude star Asellus Australis, the star that marks the splitting point for the Y-shaped star pattern.

Moon Not at Ascending Node!!

   Whoops — writing perhaps a little too early this morning I sent out a mis-dated (as in incorrect) posting about the Moon being at ascending node. It is not there today but rather on the 31st. I’ll re-post in a couple of days.
   However the sky graphic is correct so if it is clear this evening go outside and enjoy the view. Use binoculars and you could see the open star cluster, M-35, a few degrees to the right from the Moon.

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.

They’re There!


   Tuesday morning, May 23rd the thin 26.7-day old waning crescent Moon will be surrounded by planets, most of which will be difficult to see given the time of day and how faint each one is. Except for Venus.
