Monday December 19th 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.
On the morning of the 19ththe 20-day old waning gibbous Moon will be over the south-southwest horizon and will not set until close to 12 pm local time, after having risen during mid-evening local time the night before. The Moon is below Leo the Lion and above one of the longest, if not the longest, constellation. This is Hydra the many headed snake.
Does our Moon actually go around the Earth as many graphics show? 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*
