How does the Moon's angular distance from the celestial equator affect visibility at the North Pole?

Answer

When declination keeps it sufficiently far below the equator while Earth's tilt is oriented a certain way, it won't ascend.

Visibility at the exact geographical poles is determined entirely by the Moon's declination, which is its angular distance north or south of the celestial equator. For an observer standing precisely at the pole, the celestial sphere appears to rotate horizontally around them. If the Moon's declination during its orbit places it too far south (below the equator) relative to the orientation caused by the Earth's axial tilt, its entire orbital path will remain below the local horizon. This specific alignment dictates that the Moon cannot ascend above the horizon line, leading to continuous stretches of invisibility that can last for weeks or longer, contrasting with the typical daily rise and set experienced elsewhere.
