October Perigee Moon

oct26-perigee-moon   The Moon reaches perigee, (minimum distance from Earth), this month on Monday October 26th. At that time the Moon will more or less be at a distance of 28.1 Earth diameters (358,464 km or 222,739 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*

   The 13.9-day old waning gibbous Moon is 20 hours before full phase and could be considered as another “Super Moon”. This is a popular term applied to any time the full Moon phase is close or matches the time and date of when the Moon is at perigee – its closest to the Earth for that orbit, or month. This year, 2015, there are 6 Super Moons with this one being the last of the six Super Moon.
