Our Moon reaches perigee, (closest distance to Earth), for this orbit on Monday December 24th. At that time the Moon will be at a distance of 28.30 Earth diameters 224,352 miles (361,060 km) from the Earth.
Monday December 24th the waning gibbous 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.
