Lunar orbit position on

True anomaly ∠24.3°

This New Moon true anomaly is ∠24.3°. At beginning of next synodic month true anomaly will be ∠45.5°. The length of upcoming synodic months will keep increasing since the true anomaly gets closer to the value of New Moon at point of apogee (∠180°).

Moon after perigee

2 days after point of perigee on 15 December 2055 at 10:52 in ♏ Scorpio. The lunar orbit is getting wider, while the Moon is moving outward the Earth. It will keep this direction for the next 9 days, until it get to the point of next apogee on 27 December 2055 at 05:00 in ♈ Aries.
