August Apogee Moon

24aug-apogee-moon    Our Moon orbits around the Sun with the Earth and 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*.

   This very thin 28.5-day old waning crescent Moon shows only about 1% of its disk and rises just before sunrise local time. Given its thin crescent shape plus daylight it more than likely will not be noticed. New Moon is about 24 hours later. So despite it being ‘invisible’ this waning crescent Moon reaches apogee this month on Monday 25 August at 1 am CDT (6 UT). At that time the Moon will more or less be at a distance of 31.87 Earth diameters (406,523 km or 243,914 miles) from the Earth. For those keeping track, this is the 2nd greatest apogee distance for this year.
