May Moon at Ascending Node (again)

may1-ascending-node   On Thursday May 26st at 14:42 UT (9:42 am CDT) our Moon will be crossing the plane of the ecliptic moving north. This is known as the ascending node, one of two intersections the Moon’s orbital path has with the ecliptic. The ecliptic is 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.

Look for the 24-day old waning crescent Moon to rise a few hours before sunrise near the bright bluish-white star Spica.

   Our Moon orbits around the Sun with the Earth and from our perspective on the Earth the Moon appears to circle Earth each month. The Moon also has a slightly elliptical-shaped orbit allowing for the Moon to have a furthest (apogee) and closest (perigee) distance from the Earth each month.

   This month the 3.13 days old waxing crescent Moon reaches perigee today, 6 November at 9 UT (3 am CST), and will more or less be at a distance of 28.64 Earth diameters (364,954 km or 226,772 miles).
